Everyone wants to get wireless in those days. It is a kind of "what to do." The funny thing however is that nobody seems to know what they are doing when it comes to wireless. They think they crack open the box plug in some wires and go. Well, actually not so simple.

Number one, it would security. You absolutely must think about security If you deploy a wireless network in your home or office. If you think you are helping your IT department, making an access point in your office so you can move things around more freely on your desktop, you are sadly mistaken. If you have done this without creating any type of encryption, he just opened a huge door back to your company network. At home, you may not be so worried. If someone shares my internet, so what? Someone next door could easily set up a phishing scam in the apartment next door, and use your wireless connection for Internet access. So I suppose, as the door from the FBI come knocking on? Yes, yours. So encryption is a necessity, I recommend using WPA and WEP, because WEP has proven to be easily manipulated.

Item number two would be the placement. Before you create anything, you should do a site survey. Walk around your home or office and look for things that can cause interference. Map of things, and take notes. Take a laptop with Netstumbler installed and look for other wireless networks in range and see what channels are. Some things that can cause problems are:

* Cordless Phones / Microwave Ovens: These devices operate at 2.4 GHz, which is the same frequency 802.11g / N router use. Since both operate on the same frequency, which interfere with other signals.

* Concrete walls: Concrete causes a problem, not thickness or the re-bar in it, but water in the mixture. The magical thing about concrete is that never fails to cure, and water in the wall can cause signal loss.

* Report the antenna: Some people think that pointing the antenna is self motives, but it is not. You can not point your antenna like you point a finger, because the signal coming off the antenna radiates from the sides of the antenna, not the top.

* Wireless Channels: By default, most routers come pre-configured to use channel 6 or 11 (if I remember correctly). Find out what channels surrounding networks are using and select another channel. As mentioned above, NetStumbler Windows works well for this, and Kismac Kismet for Linux and MAC.

* Chicken Wire: That's right, I said chicken wire. I have not come up with this same. I had a wireless class at college, and my teacher told us about the chicken wire. Chicken wire is used in some houses they hold in the isolation walls, or used when placing plaster walls. The holes in the wire are not large enough to allow the signal waveform of the signal Wireless penetrate the wall and creates a kind of Faraday cage.

Item number three, compatibility. Almost all wireless devices are with Wi-Fi logo is supposed to indicate some kind of standard. It suggests that if you have a Belkin router, the Linksys Wireless card should be compatible. Well, 9 times out of 10 that's true, but occasionally there is that 1 time that is not true. It is almost always best practice to adhere to the same manufacturer. If you are a D-Link person, go with D-Link, Linksys, if you like, stick with Linksys and so on.

Number four, firmware. The manufacturers of their equipment frequently come out with updates firmware for their products. If you notice problems with your router or card, check the manufacturers website for a firmware update possible. Many times, the update can correct the problems you are having.

Number five, a gain or loss. Every time you have to send a signal cable has a loss. If you have a long cable that goes from your modem, CSU / DSU, etc., your router will be no signal loss. The longer the cable, the greater loss. Also, creates air signal loss as well. The farther away from the antenna, the weaker the signal. Furthermore, whenever you have an antenna, you have gain. Each time the signal leaves the antenna, or received by an antenna is a bit of gain in the signal. So what does this mean for you? Shorten the wires, if possible, and buy higher gain antennas to the router if you need the signal to travel long distances.
