I have a problem with my wireless connection.

When my computer first starts up it can't find any wireless networks (not mine or the one next door as it usually does). Wifi is turned on. If I then plug in my network cable from the modem it starts to connect to the modem. Once connected I can pull the network cable out and use wirelss - it starts then to pick up neighbouring networks as well. The problem occurs again when the computer is shut down or restarted.

Please forgive me if I have used the wrong terminology, any advice would be appreciated!

Cheers,

Lance
