I have a BT Voyagr wireless sytem, WEP key protected for my desktop and laptop. The connection with my laptop is a bit temperamental and frequently refuses to connect. The list of available networks lists a belkin connection too! I suspect a neighbour has a wireless sytem and that its interfereing with mine.
You'd be wise to remove that other network from your list, which may help.
R-click on your wifi LAN adapter in Network Connections. Select "properties" and view the Wireless tab. The available networks can be removed and once this is done, they don't come back unless the owner changes their SSID.
Play around with different channels, and have a go at fine-tuning the position of the router. This, surprisingly, can make a big difference depending on its surroundings.
Thanks for all the help, but I am making no progress at all, my laptop won't connect at all, even with a new adapter, I have a couple of other threads trying to find a solution, so maybe best to ignore this thread.
