  zoneH- Protecting your ‘wireless playground’
One of the most important issues about running a wireless network is network security. Obviously, there are people who will take advantage of an open network and leach bandwidth off it. So, in order to stave away these freeloaders from sapping your valuable bandwidth, the following are few precautions which should be considered.

While you will never read some of these tricks as part of any wireless security protocol, it’s a few noteworthy points to consider. The most important thing however, is to actually know what you are doing when setting up a wireless home network.

Firstly, disabling Service Set Identifier (SSID) broadcast on your wireless router has the benefit of hiding that wireless connection from wandering eyes. Which to put simply in wireless talk, is not to “announce” your wireless access point’s presence to prying eyes.

Unless there’s need to share wireless access point, say in a public hotspot environment, enabling SSID broadcast is similar to leaving your precious belongings on the back seat of your locked car! It’s locked, yes, but that doesn’t stop people from breaking in. Now disabling SSID broadcast is only half battle won. Since most wireless card’s software will only “see” the access point if you provide the actual identity, it’s best to use a unique name.

Do not however, use the default SSID name that comes with your access point – that can be easily hacked, and chances are most sniffing/cracking software would already have those default names hard-coded.

Use something different, say for example, “hotchilli-sauce” or something along that line

Secondly, as most wireless access points give you an option to select the transmission power, it’s advisable to reduce the transmission power to a bare minimum necessary to get you connected around your “common wireless surfing areas”

After all, it’s really pointless to go full throttle on the transmission power and enable your neighborhood wireless friends to get onto your wireless network. Reducing the power brings about two benefits, one, less power means the signals won’t be strong enough for anyone outside your home to connect, and two, you might just save some brain cells should the study on microwave frequencies proves detrimental in future.

Furthermore, less transmission power means less electricity usage.

Finally, an alternative option is to employ an unusual encryption method.

The D-Link DWL-900AP+ coupled with the D-Link DWL-650+ AirPlus PC Card enables users to user 256-bit Wired Equivalent Privacy (WEP) encryption through the 802.11b+ protocol.
This means that the 802.11b+ is not compatible with regular 802.11b cards such as the Orinoco Gold which only supports the de facto 802.11b 64-bit or 128-bit WEP encryption.

Implementing all of these steps might seem tedious, but it ensures that you will have exclusive rights to play in your own wireless playground.
