Upgrade your Wi Fi network to 802 11n
The most straightforward way to support 802.11n is to add an 802.11n wireless access point like the D-Link 1522 xTreme N Duo. This can be plugged directly into your router. To save a lot of time reconfiguring your wireless devices, connect the 802.11n wireless acceess point directly to your existing router. My router acts as my internet gateway and has an IP address of 192.168.1.1.
If you use a Wi-Fi router, disable Wi-Fi and copy the Wi-Fi settings onto the access point. If all goes well, you should have an 802.11n network. Your existing devices should connect automatically.
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.
