O.K. It’s time to dispel the myth about networking! Although networks, (wireless or otherwise) used to be used primarily by businesses and schools, times have changed. There are now huge benefits to installing a network at home. The thing that put’s many people off is the fact that they are notoriously complicated to set up and get working. Well, as technology had advanced this process has become a darn sight easier and if you are interested in setting up your own network then don’t panic. As long as you have a little patience, you can do it. There is an abundance of information on the internet to help you get through any problems so, if possible, keep one computer off of your network, (but connected to the internet) to start with. This way you will still be able to connect to the web and get any advice and tips you need during your installation and set-up.
For those that consider yourself novices and are not sure why having a wireless network in your home is beneficial, let’s take a look at some of it’s uses. Many of us now have more than one computer in our homes. Whether you have children with a PC in their room, or a laptop that you use around the house and in the garden there are some great benefits to connecting them all together. First of all, Think about your printer. Why bother having a printer for every PC, or transferring documents to the computer that’s attached to the only printer, when you can use a network to let your printer receive information form all your computers? Of course the other bonus is that, with a wireless network your printer can be put anywhere in the house out of the way. If like me, you have a computer in your living room, then hiding the printer away in the cupboard is perfect.
So there’s one advantage. Now, what about music, videos and other media? There is no need to waste time and money putting music onto all of your hard-drives. By creating a Wireless home network you can store all you media on one hard-drive and access it via the network. Of course these are only examples. Another obvious benefit is the ability to access all of your documents from any computer in the network. If your chilling in the garden with your laptop and need a file from your desktop PC, no problem. Just access it via your wireless network. Now we’ve covered some of the more obvious benefits to installing a wireless network let’s take a look at how to do it.
The first step, without a doubt is planning. You need to know what you require from your network. How many computers you want to attach, where your computers are located, and any other peripherals, (such as printers). Once you have this worked out it will be much easier to determine what equipment you need. When looking at equipment I would recommend that you set up your network using the 802.11g technology, as it is the most compatible.
So, let’s take a look at what you will need. First of all, you’ll want a broadband connection. Secondly, you need a wireless router. And third, a wireless network adaptor for each computer that is going to be part of your network. For desktop PC’s, buy a USB adaptor and for laptops, get a PC card adaptor, (this will plug into your expansion slot). Before buying your wireless network adaptor, check to make sure your PC doesn’t already have this feature built-in. If it does then there is no need to buy an additional one. Also, buy your network adaptor and wireless router from the same company. This will make things far easier when setting up. Now you have your equipment, it’s time to get it up and running.
Unplug your modem and connect it to your wireless router. You will notice that your router came with a network cable. Plug one end into the back of the router, (the port labelled internet, or Wlan, or Wan) and the other end into your modem. If you are unsure which port to connect your cable to, you will need to refer to the instructions, as routers vary depending on the make. Now plug in your modem again and connect to the Internet. Next, plug in your router and turn it on. After a few 30-60 seconds you should see lights that indicate the router is connected to the modem. Now it’s time to configure your modem.
Your router will have come with an address. Open Internet explorer and type this in the address bar. You may need to enter the default password at this stage. This also comes with the router. You should now be looking at the configuration page for your wireless router. Don’t panic if it looks technical, you only need to change a few things. First of all you will need to give your network a name. Choose something that is not too easy to guess, as this will help with security issues, and type this in the SSID section. You should also see a section that asks for a WEP or a WPA. Choose something long and random as this will prevent hackers getting in, you don’t need to remember this anyway. Now you need to create an ‘administrators password’. Again choose something unique containing letters and numbers, (you will need to remember this one though). Now that’s done, disconnect the network cable from your computer.
Now you can connect your computers. Before doing anything, make sure you have “Windows Service Pack 2″. Now, repeat the following steps for each computer.
If you have purchased a USB network adaptor, plug this into a USB port on your computer. If you have a network card for your laptop, plug this in your expansion slot. Windows should now detect your new hardware and ask you to insert the CD that came with it. Do this, and follow the on-screen instructions. Once you have completed this you will see a new icon in your taskbar, (bottom right of main windows screen). Right-click it and select ‘View Available Wireless Networks’. You should now see the name of your wireless network, if you don’t, click refresh. Select that network and click connect, enter the network key you will have typed in earlier and wait for it to connect. Now you can close this window.
Finally you need to………..
Do Nothing, that’s it! Congratulations, assuming everything went smoothly then you just set up a wireless home network. If you encounter problems, then visit www.wirelessnetworkinstallations.com for more advice. Failing that, call the technical support that came with your router and they will be able to steer you in the right direction.

A Novice Guide To Setting Up A Wireless Network
March 9th, 2010Wireless Network Security: How to Use Kismet
December 13th, 2009
Kismet is a wireless network detector / sniffer which can give you a vast amount of information about wireless networks. Wireless network security flaws are well documented but often very hard for the common person to understand. I will be showing you how to use kismet with out even having to install Linux, or compile kismet.
First you need to proceed to remote-exploit.org and download and burn their Auditor CD. (IF you don’t know how to burn an ISO image, go to Google). This version of Linux doesn’t install or modify your hard drive; it will boot from the CD and use a Ram Drive (On your Memory).
Auditor is not only a great tool for testing wireless network security with kismet but it also has many other computer security tools on it as well.
Client Window
Next, to start Kismet proceed to the Linux version of the start menu, and press Auditor.
Now proceed to the wireless /scanning/kismet tools/kismet.
Once you click on Kismet it will ask you for a default location to place the Kismet log files for analyzing later, just press the desktop or temp file.
Now I will show you how to use Kismet. When kismet initially opens you will see a greenish box with numbers and network names (If any are near you) clicking away don’t be overwhelmed. (Also I can’t show you how to use kismet if you don’t have the correct wireless adapter, get an ORINICO Gold Classic Card off EBAY.) The Orninco gold classic card will be automaticly detected by auditor linux.
The Kismet columns will show the wireless networks SSID (Name), Type of device (Access point, gateway) Encryption or no Encryption, an IP range and number of packets. Kismet will pick up hidden networks with SSID broadcast Disabled also, Netstumbler will not.
Now Press H, to bring up the Help Menu. This will give the nuts and bolts on how to use kismet. If you tab down to the network you are auditing and press “C”, Kismet will show you all the computers that are using that wireless access point / gateway. This Kismet screen will show you the clients MAC address, Manufacture of Wireless Adapter, IP address range and traffic.
Kismet: Help Menue
Now to get out of that screen press “Q”. Tab Down on the Main Kismet Screen to another SSID and press “I”. This Kismet window will show detailed information about the wireless network. The Kismet detail screen will show the type of network (Infrastructrure / Adhoc), signal strength, channel, encryption type, and much more.
Kismet will also give you sound alerts when new wireless networks are discovered or security alerts or suspicious clients are in range. Suspicious clients would be people like you who are using Kismet or Networkstumbler. Unlike you these could be Wardrivers looking for venerable networks to hack into.
Kismet Alert Page
You can prevent War drivers from discovering your wireless network by performing a proper site survey which will help limit signal bleed off to unneeded areas. You should write down the suspicious MAC address and keep an eye on your access logs. If the War Drivers are really stupid just look out your window and look for cars with weird antennas.HA HA HA.
Kismet is more than just a tool to discover wireless networks; it can be used in conjunction with other tools to crack WEP/WPA. Many websites will claim that WEP can be cracked in less that five minutes. This is only half the truth because it could take many hours,days,months to gather enough packets to crack. Good luck and have fun learning the more advanced applications of kismet.

Computer Network – Comprehensive View – Part 2
November 13th, 2009
Wireless networks located in multiple categories, depending on the size of the physical area that can be covered by network.
The following types of wireless network meet the needs of multiple users:
* Wireless personal – Area network (PAN).
* Wireless Local Area network (LAN).
* Wireless Metropolitan-Area network (MAN).
* Wireless Wide – Area network (MAN).
This is using the expansion all major cables for wired networks (such as LAN or WAN) used for years before it enters the wireless network.
Each type of wireless network has the advantages of complementary meet multiple requirements. The following paragraphs explore each type of wireless networks in a concise manner.
Wireless networks (PANS):
The area of wireless networks is a relatively short (up to 50 feet) and most of their effectiveness to meet the needs of a small room or in the cargo area. PANS networks is the performance of the average of data rate of up to (2MBPS). Imperatives followed these advantages for the replacement of cables in many cases.
PAN wireless network includes a person synchronize personal PDA with his laptop computer or personal computer. In a similar, PAN wireless network can provide radio communication to the printer. The advantage of the abolition of knots in the wire when using this type of computer is very useful, where the initial installation of the equipment is easy.
Wireless networks (LANS):
Networks wireless LANs provide high performance within and around office buildings and labs, and homes often have the users in these areas laptop computers, personal computers, PDA screens and processors to support large applications. LANS meet the requirements of communication for these types of computers effectively.
For example, in the work it can be installed the wireless LAN network to provide mobile access to the common applications of laptops. This type of system, the user can, while far from his office, take advantage of network services from the conference rooms and other rooms. That allows staff to be more effective while working away from their offices and more cooperative with each other.
Wireless networks LANS provide the performance levels enable applications to operate smoothly. For example, the wireless network LAN users can easily see e-mail attachments or a large scale video server of the invisible with data rate up to (54 MBPS). Wireless LAN network can meet only networks with the limits of web applications a house or office.
Wireless networks (MAN’S):
MAN’S wireless network includes areas with the size of cities.
Wireless Service Providers (WISPs) Provide wireless networks in cities and remote areas in order to provide homes and firms for wireless communications. Wireless networkings MAN provides the positive benefits and are appropriate when it is impractical to install a traditional wired communications such as (DSL and cable modem). Wireless networks WANS are effective when the right path for the cable systems have made it not possible or too expensive.
Wireless networks (WAN’S):
MAN networks known as mobile wireless applications cover a large area, such as state or continent. Because of the economic side, the operator is able to do remote deployment of the operational infrastructure of the wireless network MAN in order to provide relatively inexpensive long-distance communication for a lot of consumers. It is possible to distribute the costs of such a deployment across multiple users. It provides low fees -subscription.
