Rfxcel Verification Router Service

rVRS is a routing system to send product information between distributors and manufacturers. In accordance with HDA requirements, a manufacturer stores all product identification information locally, which must be connected to a third-party routing service. Upon receiving a salable return, the distributor captures the product data and sends it to a third-party router service, which then sends the query to the corresponding manufacturer's database.

Through rVRS, we collect the IP address of the manufacturer's EPCIS repository, as well as their GTIN (Global Commercial Item Number), to provide the most accurate information router survey.

rVRS is based on industry standards and the process proposed by HDA:

• Step 1. When a wholesale distributor receives a salable return, he scans the product identifier (in any case or the first unit) , and acquires the serial number and GTIN for the product.
• Step 2. The wholesale distributor sends both the serial number and the GTIN to rVRS. rVRS looks for the manufacturer's EPCIS IP address.
• Step 3. rVRS sends the data to the EPCIS for verification purposes.
• Step 4. The manufacturer's system responds to the request with the corresponding serial number and GTIN, or with the current status of the units in question.
• Step 5. The manufacturer's VRS sends the data to the wholesale distributor that needs it for salable return purposes.

Only through collaboration, the industry will comply with DSCSA compliance. It is crucial that solution providers have a flexible system that allows them to work closely with customers and their partners to follow industry standards and meet compliance requirements. There is no 'one size fits all' to meet DSCSA or other deadlines and global compliance requirements. rfxcel works closely with manufacturers and wholesale distributors to determine their needs and build a product that is best for the customer.

business wifi routers

Buying a router for your business is not as simple as choosing another consumer product from an internet store with a five-star rating or finding the best price in an electronics store in your neighborhood.

Your company has serious needs, such as supporting dozens of users on the network and blocking company data to protect themselves from snoopers. Before buying the network equipment, it is necessary to understand the types of equipment available, as well as their uses and typical characteristics. Read on to know the basics when buying a router along with the explanation of the features you should look for business wifi routers.

Router types

If you only need a dozen Wi-Fi devices and devices at most, a simple home user router or a small business router should be enough. Typically, these routers offer sufficient Wi-Fi coverage for an office space of 500 or 600m2. They will provide four Ethernet stations for network cabling equipment, network storage or additional wireless access points for more Wi-Fi coverage.

If you need to support more than a dozen computers and devices, or devices, or if security is crucial to your operations, you need more than just a simple wireless router. You have two main ones to consider.

VPN Router / Firewall: These products, one step beyond a basic wireless router, can be wireless or just Ethernet; The latter requires adding access points for Wi-Fi connection. These routers have an integrated virtual private network server, and sometimes offer advanced features, such as VLAN support and various SSIDs (if they are wireless).

Gateway or UTM firewall: These routers include advanced features and are usually Ethernet with only four to eight ports, which requires separate access points for Wi-Fi connectivity. In addition to serving as a router and Internet gateway, in addition to providing a VPN server and firewall, these units also typically include protection against viruses and malware, content filtering, anti-spam functions and intrusion detection and prevention.

Additional security features usually require monthly or annual subscription fees. However, you will still need protection against viruses and malware on each user computer due to the limitations of network-based products, since they cannot monitor local behavior on PCs or inspect SSL encrypted traffic.

As you buy, you will probably find other buzzwords that refer to devices that are similar to UTM products, including unified security gateways and Internet security devices.

server maintenance jobs

A server is software hosted on a very powerful computer whose purpose is to store and manage information. The servers remain on 24 hours a day , because they are the ones that store the information that is required to have access at all times.

Servers , like anything else, need periodic maintenance , as well as software and hardware updating, since not all the information they store remains static server maintenance jobs.

Hardware

Servers should be kept in an isolated place at a low temperature Since they remain on all the time, they are more prone to overheating than a computer.

• Step 1 . To maintain them, you have to turn them off and unplug them .

• Step 2 . The maintenance person has to touch a metal surface to discharge static electricity.

• Step 3 . When they are turned off and unplugged, they must be cleaned inside with a liquid product or a foam  to remove dust and accumulated trash. It is important to check that all parts work properly and that the fans provide sufficient ventilation.

  software

  The servers contain sensitive information, so it is important to ensure that there are no unauthorized entries to your databases.
  • Updates . To avoid that and for the proper functioning of the server, it is important to keep the software, antivirus and firewall updates up to date .
  • Backrests . It is also necessary for the server to perform automatic backups from time to time , so that the information is not lost if the hardware is damaged.
  Servers are equipment whose assembly, installation and maintenance are different from those of a computer and, therefore, their maintenance must be performed by trained personnel .

What is a server and what is it for?

A server is a set consisting of hardware and software designed to receive requests of different types and respond accordingly, sometimes returning information such as a web server that returns web pages, images, videos, etc. or receiving data such as for example an email server.

A server a computer that receives requests from other computers connected to the same network or to the Internet and is responsible for responding to those requests depending on the function, in some cases it may be that it receives requests in order to return information or data as a page web or you can be prepared to receive information as a mail server technicians.

In the following video we can see with a little more clarity what a server is and what it is useful for, as well as some of the most popular services:

Server types

Different types of servers can fulfill multiple tasks, many of them known as we listen to them every day such as web servers or mail servers or other less named but equally important as DHCP Server or DNS Server that we use to daily and we don't know.

Let's now see the different types of servers that exist on the Internet:

• Mail Server: one of the best known services is undoubtedly the email service that is responsible for receiving, storing and of course allowing access to mail, it really is not a single service but a group of services, at least one service SMTP to send and receive mail and a POP / IMAP server to view it, also usually works in conjunction with an Anti-virus and an Anti-Spam. The mail server is one of the most used Internet technologies today.
• VOIP server: it is a server that allows you to use the local IP data network to channel telephone traffic as it is a conventional telephone network and with the appropriate hardware to interconnect with the PBX telephone exchange itself or interconnect through an external network service conventional telephone
• Fax Server: it is a service that allows you to send and receive documents, instead of receiving them and sending them from a paper document like the traditional FAX, this fax service allows you to do it directly with a digital document, that is, when a document arrives a document is created instead of going out of paper on the fax, in the case of sending the document is sent directly through the telephone system as if it had been scanned.
• Proxy server: a proxy server is a server that allows access to other networks through it, it can be used in a local network to allow computers to surf the internet in a controlled way, such as determining which pages they can see, which ones they cannot see , at what times, as well as controlling which user accesses, where you browse, what pages you visit, how much time etc. A public proxy can be used to hide the IP of the source, which does not mean that it cannot be traceable.
• VPN server: they are the initials Virtual Private Network and it is a service that allows secure communications to be established through an encrypted tunnel through an insecure network such as the Internet, a VPN link can be used both to join two geographically separated networks or as a preservation mechanism of privacy and anonymity to some extent on the internet
• Web Server: it is next to the mail service the web server is the most named service, it is the one that allows web pages, images and videos to be published and distributed on the Internet, also allows to give foundation to http-based applications. As web servers we have Apache, Nginx, LiteSpeed ​​or IIS
• Database Server One of the biggest problems of computing has always been how to save information and data quickly, safely, reliably and be able to recover them quickly when needed, the great solution for this is database servers . A database manager allows us to insert, update, delete, list, sort, measure, account, control and manage huge amount of data with ease.
• DNS Server: The Domain Name Server server is a server similar to a database that allows you to locate the server that hosts this website or the mail system from an internet domain. If you want to know in depth how this service works we recommend you read about the DNS Server , where the operation is explained in detail.
• DHCP server: this service is almost unknown to the common user however it is the most used even without realizing it, this service is the one that manages the IP addresses in a network and when connecting a computer to the network or a phone to the WIFI you Assigns a unique IP address on the network. It is an indispensable service in any network to handle IP in a simple and secure way avoiding conflicts in the network, it is so important that in fact every home router includes a DHCP server that if it did not exist we should assign an IP by hand making sure it is not busy A cumbersome process without a DHCP server.
• FTP server: it is one of the oldest servers that exist, they are the initials of File Transfer Protocol, a protocol that allows access to a server to upload, download, update or delete files from the server. The FTP server is still used today because among other things, for example, it allows you to easily and securely access a hosting to manage the files of a website,
• SSH Server: they are the initials of Secure SHell, a service that allows you to remotely access the console of a server or any pc under an encryption layer that guarantees security and privacy, provides a console as if accessed locally and allows you to execute any necessary command on the computer, it can also be used to transfer files securely between two computers, be they servers or workstations. The SSH server is the most used to upload and download information, as well as to execute commands on servers.
• File Server: it is a server designed to store files and place them accessible to users, both in a local LAN network or through the Internet, it can take different forms, it can be implemented through different protocols, among others NFS, FTP or SMB / CIFS in Microsoft or Samba systems, its equivalent in Linux.
• Security Server: it can cover different cases, sometimes Firewalls are often referred to as firewalls, a service is usually called a server that adds an additional layer to the communication between the local network and the Internet such as a VPN or also to an Intruder detection system.
• Print Server: the print server is a service that allows you to manage the queue of documents pending printing on one or more printers, there is also a separate hardware device called print server fulfills the same function, the difference is that it works independently of any PC or server.
• Cache Server: The cache server is a service that allows you to store files and even results of database queries in a fast-access area in order to speed up applications and web pages. For example, very frequently requested files are stored in memory where access is much faster than requesting them from the storage unit (HDD or SSD) or results of repetitive SQL queries are stored in memory or in files instead of being made to the database. data with a cost and CPU time.
• Load balancing server : is responsible for distributing the load to other servers that are behind, thus ensuring the stability of the applications that run on them, or their databases. They are usually a specialized hardware in these tasks, or software that does the load balancing once installed in the operating system (as in the case of Nginx).

Due to the aforementioned, it is very important that a company has a professional in the area of ​​support and maintenance of fixed or payroll computers.

Support and Maintenance: Company Image

Having good support and maintenance of computers goes hand in hand with the image of the company. The professional in the field of support and maintenance is a fundamental part of the good image.

In an era where technology is a fundamental part of the development and operation of a company, neglecting this part, in turn the image of it is neglected and can change rapidly.

Think for a moment as an employee of a company, if a computer stops working or a computer system is frozen and lets us continue with your work and your day's goals cannot be realized due to this failure, and this is a failure constant, what image would you have of that company?

Now, think as a customer, if a system within a web page or a tool provided by a company as part of the service, does not work or is inefficient, and this happens constantly, what would you think of that company? Would you continue with her services?

Well, there is the importance of these professionals and why it is important for the image.

What can a professional do in Computer Support and Maintenance?

The most effective method to perform preventive upkeep on a server

The servers are the ace gear or those hardware that offer support to PCs that are associated with that server through a LAN . Servers, in contrast to terminal gear, work constantly and have for all intents and purposes no rest. It is hence, that every now and then it is important to perform preventive support to keep the activity of the servers as ideal as could reasonably be expected and stay away from blunders or circumstances that may diminish the activity of the system. Today, we will see a few hints for compelling upkeep of servers in little LAN systems maintenance technician job description.

Setting up the gear for support

The initial step to perform preventive upkeep to our system or server hardware is to set it up for the support procedure. To do this, we should kill the hardware and separate it from the center points or association frameworks to the remainder of the system gear support professional employments.

When the server is liberated from associations, the time has come to expel it from the rack where it is facilitated. We place it on a level and safe and totally protecting surface

Beginning equipment support

This progression is basic, however significant, since as long as the gear is spotless inside the temperature will rise less and the cooling frameworks will work with less exertion.

To start upkeep, first, we clean the outside of the server with a dry fabric or extraordinary towel and expel all the residue, we can utilize exceptional cleaning fluid. When the outside part is cleaned, the time has come to open the server and expel all the residue from the interior part with a compacted air gadget and fine brushes and brushes.

It is advantageous to utilize an assurance fluid (splash) for hardware or electrical circuit sheets, and if vital, we can include or change RAM memory sheets or some other gadget, for example, including another hard plate or cooling framework. At that point, in the wake of finishing the equipment improvement process, the time has come to close the server, and interface it to a voltage controller and a screen to play out the subsequent stage of the support procedure.

Beginning programming support

When we associate the server to a force source and to a screen, console and mouse, the time has come to play out a total programming update, that is, update the framework with the most recent form of Windows Server or Linux Server that we have or any Another framework that our server employments. Right now, guarantee that vulnerabilities will be limited.

In the wake of refreshing the server programming, we can run an antivirus in a Live manner, totally detached from the Internet. It is prescribed that it be an ongoing adaptation with the goal that it can identify any oddity. When the dangers have been executed and wiped out, assuming any, we continue to clean transitory documents. The time has come to kill the gear and evacuate the source, the screen and different actualizes that we utilized for the past advance and set up the hardware to associate it again to the system.

Introducing the server again on the system.

Before introducing the server again into the system, it is advantageous to interface it to a uninterruptible force source or UPS, to maintain a strategic distance from disappointments because of a drop in the force supply. At that point, we put the server in the rack where it was initially. Presently, we associate the server to the system with every one of its links and centers, turn it on to check the activity of the considerable number of utilizations and administrations of the system and we will have finished the support procedure.

Checking the activity of the UPS

To guarantee legitimate activity of the system when electrical disappointments happen, it is advantageous to expel every single electrical association from the UPS and check if the gear stays on. This is the principal sign that the UPS is functioning admirably, not doing so is harmed and it's a great opportunity to transform it.

A subsequent test comprises in timing the time that the hardware stays on with the UPS without power supply to check that the power reinforcement time corresponds with that provided by the maker. Else, we ought to think about changing the gadget. Additionally, we should confirm that the UPS sends cautions by email and sound-related notices cautioning that the vitality is running out. Right now, will have a decent electrical insurance framework that will keep our hardware buckling down enough to turn them off and evade breakdowns during a disappointment.

With these tips, we can keep a Lan organize server working in adequate conditions for quite a while. We should recall that the server hardware must be in an all around cooled spot to abstain from overheating .

how wifi works

In figuring , it is known as Wifi (got from the Wi-Fi brand) to a media communications innovation that permits remote interconnection among PC and electronic frameworks ,, for example, PCs, computer game consoles, TVs, PDAs, players, pointers, and so on .

This innovation permits these gadgets to interface with one another to trade information , or associate with a remote system passage, consequently having the option to have an Internet association.

What's more, despite the fact that the Wi-Fi brand recognizes a partnership that guarantees the essential guidelines of innovation that has this association ability, the term Wifi is generally used to allude to the last mentioned and not to the organization remote lan .

Wifi rose as a reaction to the requirement for institutionalization and similarity in the remote association models of the different computerized gadgets, additionally conquering other unsupported types of association, for example, Bluetooth, GPRS, UMTS, and so on. Not at all like these, Wifi utilizes radio waves as a vehicle for transmitting data .

This innovation is intended to interface gadgets over moderately short separations (100 meters greatest), particularly in conditions that offer a ton of obstruction or commotion to the sign, for example, that delivered by the immersion of the radio range because of variety of discharges. What's more, it is a more slow association than the wired one , yet essentially progressively agreeable and adaptable.

The other inconvenience of associations of this sort has to do with security, since any gadget that gets the sign is probably going to approach the sending point . This is typically arranged through passwords and other security systems, however the chance of a digital infringement is constantly idle.

Wifi types

Different sorts of Wifi are known, as per the benchmarks they use for their recognizable proof and which can be recognized into two classifications:

2.4 GHz band . Here are the IEEE 802.11b, IEEE 802.11ge and IEEE 802.11n guidelines, whose dealing with is universal and permits velocities of 11 Mbit/s, 54 Mbit/s and 300 Mbit/s separately. Be that as it may, the sort has the best obstruction, since the 2.4 GHz band is additionally utilized by Bluetooth and different remote frameworks how wifi works.

5GHz band . The new kind of Wifi, known as WIFI 5, applies the IEEE 802.11ac standard and is taken care of in a totally new and obstruction free channel, in this way, in spite of being an ongoing innovation and having a 10% disservice not as much as range, it is viewed as amazingly advantageous given its dependability and speed.

Wifi works comparably to mobile phones or radio transmitters. At first, the information of an Ethernet association is unscrambled by a common modem , which transmits its decoded sign to a remote switch or switch , which transmits it as radio waves around it. Much of the time the two gadgets as of now comprise of just one, which satisfies the two capacities: it gets the broadband sign and deciphers it as radio waves.

At that point, the Wifi gadget on our PC or wireless, to name a model, deciphers these radio signals and changes over them into data once more. The cycle is then rehashed when our gadget sends as opposed to getting data, etc and all the while

built in wireless network

1. Introduction

Since the dawn of humanity, a fundamental issue with respect to development and progress, it has been the need for communication between each other, present throughout history .

In recent years the new achievements of technology have been the emergence of computers, telephone lines, cell phones, wired and wireless networks , as well as satellites built in wireless network.

The main principle of communication is established through speech in the relationship between sender, message and receiver. But today's technology should not only refer to voice transmission, but should try to cover a larger gamma of applications, call it data transmission . Given this need, computer networks such as the intranet , extranet and the Internet arise .

Regarding the exchange of voice and data, it is essential to be connected to the entire world through the Internet, where some problems arise regarding the application of wired networks because it is necessary to transport the equipment either inside a room like inside an office .

When this need arose, it became part of a larger study group , from wireless networks, data transfer via infrared, as well as in the application of satellite networks. The same ones that have managed to satisfy this need by achieving the connection of existing users in different parts of the world.

The application of wireless technology has been booming in transmission speeds, although without competing with the use of wired networks or the use of fiber optics , however they satisfactorily cover the need for user movement .

2. Wireless technology approach

Based on the definition of wireless, this term refers to the use of wireless technology which allows the connection of several computers to each other.

This is how it has become a focus of study for data transmission issues, acquiring greater interest in places where the installation of wired networks is not possible.

The use of this wireless technology allows the cables to be forgotten without the need to stop establishing a connection, disappearing the limitations of space and time , giving the impression that an office can be located anywhere in the world.

An application of this case could be the relationship established between employees located in a place other than their work center and a network acquiring the company greater flexibility. The devices are connected to other wireless devices in order to provide dynamic workers with a strategy towork more effectively and with fewer complications.

Desktop applications also make the network load lighter.

Using wireless technology determines that the company increases its productivity and efficiency , in this way the employee is dedicated exclusively to what he knows best, avoiding the inconveniences of a technological nature.

What equipment is needed for a wireless home network?

This tutorial will guide you through the process of planning, building and testing a wireless home network. Although conventional wireless networks have made great progress over the years, wireless technology and terminology remain a bit difficult for most of us to understand. This guide will also help small businesses online wireless networking equipments!

Build a wireless LAN, step by step

You can build any typical wireless home network, a wireless LAN (WLAN), using this simple three-step approach:

1. Identify the WLAN design that best suits your situation. 2. Choose a good wireless device. 3. Install the device and test the configured WLAN.

I will break down each of these steps in more detail.

Ready for wireless technology?

This assumes that you have already made an informed decision to use wireless technology instead of building a traditional wired network. Prices have dropped dramatically for a few years, when wireless equipment was quite expensive, so network hardware is much more affordable now, but wireless networks are still not for everyone (yet). If you are not sure that wireless technology really meets your needs, be sure to research the different capabilities to decide what is best for you.

Benefits of wireless technology

Wireless technology offers tangible benefits compared to traditional wired networks. Have you ever tried to quickly find a recipe on the net while cooking in the kitchen? Do children need a networked computer in their bedroom for school projects? Have you dreamed of sending email, instant messaging or playing games while relaxing in your outdoor patio? These are just some of the things that wireless technology can do for you:

Next stop - Terminology

The field of computer networks once sat directly in the domain of technicians. Equipment manufacturers, service providers and experts studying the field of networking tend to be quite heavy in technical jargon. The wireless network industry is gradually improving this legacy, making products more consumer friendly and easier to integrate into the home. But there is still a lot of work to do for the industry. Let's take a look at the common jargon of wireless home networks and what this all means.

When looking for wireless equipment to buy, or when talking about wireless networks with friends and family, you should have a solid knowledge of this basic terminology.

What is a WLAN?

We have already said that a WLAN is a typical wireless home network. This is because a WLAN is a wireless LAN, and a LAN is a related group of networked computers located in close physical proximity to each other. LAN networks can be found in many homes, schools and businesses. Although it is technically possible to have more than one LAN in your home, few do so in practice. In this tutorial, we explain how to build a single standard WLAN for your home.

What is Wi-Fi?

Wi-Fi is an industry name that is used to market wireless network products. You will find a black and white Wi-Fi logo or certification emblem on virtually all new wireless equipment you buy. Technically speaking, Wi-Fi means compliance with the 802.11 family of wireless communication standards (described below). But because all conventional wireless home network equipment uses 802.11 standards today, basically the term "Wi-Fi" distinguishes only wireless equipment from other network equipment.

What is 802.11a / 802.11b / 802.11g?

802.11a, 802.11b and 802.11g represent three popular wireless communication standards. Wireless networks can be built using any of the three, but 802.11a is less compatible with the others and tends to be a more expensive option implemented only by larger companies.

What are WEP, WPA and Wardriving?

The security of wireless home networks and small businesses remains a concern for many. Just as we use radio or television receivers to tune station broadcasts, it is almost as easy to pick up signals from a nearby wireless home network. Sure, credit card transactions on the Web can be safe, but imagine your neighbors spying on every email and instant message you send!

A few years ago, some technicians popularized the practice of conducting war to raise awareness about this vulnerability in the WLAN. With the help of cheap and homemade equipment, war drivers walked or drove around the neighborhoods spying on the wireless network traffic emanating from nearby houses. Some wardrivers even registered their computers on the homeless WLAN networks of unsuspecting people, essentially stealing free computer resources and Internet access.

WEP was an important feature of wireless networks designed to improve your security. WEP mathematically encodes (technically speaking, encrypts) network traffic so that other computers can understand it, but humans cannot read it. WEP technology became obsolete a few years ago and has been replaced by WPA and other security options. WPA helps protect your WLAN from access controllers and nosy neighbors, and today, all popular wireless devices support it. Since WPA is a function that can be activated or deactivated, you just have to make sure that it is configured correctly when configuring the network.

Next - Types of Wireless Equipment

The five types of equipment found in wireless home networks are:

• Wireless network adapters;
• Wireless access points;
• Wireless routers;
• Additional wireless antennas;
• And wireless signal amplifiers.

Some of these devices are optional depending on the configuration of your home network. Let's examine each piece separately.

Wireless network adapters

Each device that you want to connect to a WLAN must have a wireless network adapter. Wireless adapters are sometimes also called NICs, short for Network Interface Cards. Wireless adapters for desktop computers are usually small PCI cards or, sometimes, USB adapters similar to cards. Wireless adapters for laptops resemble a thick credit card. Today, however, an increasing number of wireless adapters are not cards, but rather small chips embedded within laptops or handhelds.

Wireless network adapters contain a transmitter and a radio receiver (transceiver). Wireless transceivers send and receive messages, translate, format and, in general, organize the flow of information between the computer and the network. Determining how many wireless network adapters you need to buy is the critical first step in building your home network. Check the technical specifications of your computers if you are not sure that they contain built-in wireless adapter chips.

Wireless access points

A wireless access point serves as a central WLAN communication station. In fact, they are sometimes called base stations. The access points are thin and light boxes with a series of LED lights on the face.

Access points connect a wireless LAN to a pre-existing wired Ethernet network. Home network connectors typically install an access point when they already have a broadband router and want to add wireless computers to their current configuration. You must use an access point or a wireless router (described below) to deploy hybrid home networks with or without cables. Otherwise, you probably don't need an access point.

Wireless routers

A wireless router is a wireless access point with several other useful features added. Like wired broadband routers, wireless routers are also compatible with Internet connection sharing and include firewall technology to improve network security. Wireless routers look a lot like access points.

A key advantage of both wireless routers and access points is scalability. Its powerful built-in transceivers are designed to broadcast a wireless signal throughout the house. A domestic WLAN with a router or an access point can better reach corner rooms and backyards, for example, than one without it. Similarly, home wireless networks with a router or access point support many more computers than those without. As we will explain in more detail later, if your wireless LAN design includes a router or access point, you must run all network adapters in the so-called infrastructure mode; otherwise, they must be run in ad-hoc mode.

Wireless routers are a good option for those who build their first home network. See the following examples of wireless router products for home networks:

Wireless antennas

Network adapters, access points and wireless routers use an antenna to help receive signals on the WLAN. Some wireless antennas, such as those of adapters, are internal to the unit. Other antennas, such as those of many access points, are visible from the outside. Normal antennas that are delivered with wireless products provide sufficient reception in most cases, but you can also install an optional additional antenna to improve reception. Generally, you will not know if you will need this equipment until after completing the basic network setup.

Wireless signal amplifiers

Some manufacturers of wireless access points and routers also sell a small piece of equipment called a signal booster. Installed together with a wireless access point or a router, a signal amplifier serves to increase the power of the base station transmitter. It is possible to use signal amplifiers and additional antennas together, to improve both the transmission and reception of the wireless network simultaneously.

Both antennas and signal amplifiers can be a useful addition to some home networks after the basic elements have been installed. They can make computers out of reach again within WLAN range, and they can also improve network performance in some cases.

WLAN Settings

Now that you have a good knowledge of the parts of a wireless LAN, we are ready to configure them according to your needs. Do not worry if you have not decided on a configuration; We will take care of all of them.

To maximize the benefit of the instructions below, have your answers ready for the following questions:

• Do you want to expand your home cable network with a WLAN or are you building a completely new network?
• How many wireless computers do you plan to network and where in the house will they be located?
• What operating systems run / run on your networked computers?
• Do you need to share your Internet connection between wireless computers? How else will you use this WLAN? Share files? Network games?

Installing a wireless router

A wireless router supports a WLAN. Use a wireless router in your network if:

• You are building your first home network or
• You want to rebuild your home network to be completely wireless, or
• You want the installation of your WLAN to be as simple as possible.
