Wireless networking is a significant advancement in networking technologies, especially for home users allowing computers in different rooms to access the internet and a home LAN without the need for difficult and time consuming cabling. However, wireless networking also brings many security risks. Most people setup their wireless routers with minimal (or without any) security, meaning anyone with a laptop and some spare time could logon and gain access to the wireless network. An article at the Wi-Fi Alliance www.wi-fi.org/OpenSection/secure_the_network_setup.asp provides an excellent guide on securing wireless networks. If you find your wireless router does not support some of the features (e.g. WPA) then check the manufacturer’s website of your wireless router, as many manufacturer’s release firmware updates for routers which include new functionality (e.g. WPA) and other fixes. And remember: don’t just rely on one security measure to protect your wireless network - incorporating many different measures (e.g. WPA, disabling broadcast of SSID, using MAC tables) will greatly increase the security of your wireless network!
