Changing the IP address of your network interface card in Windows
By highlighting the IPv4 settings and selecting Properties, you can change the IP address of the network interface card. The first step is to make sure you can see the access point at 192.168.0.50 - which means setting the IP address of your network to a number on the "0" subnet such as 192.168.0.7.
Devices that comply with the 802.11n standard are designed to allow you to access super-fast wireless networking at home or in the office to support video conferencing, Skype, BBC iPlayer, ITV Player, 4oD and access your music, video and pictures from a media server without any loss in quality. Here's how you upgrade an 802.11b and 802.11g network.
