Hello Druchii,
Thanks for you reply. I have followed your instructions but have not come up with what you have said. I did not mention that the laptop is Windows XP, so is the main PC but the other, new desktop is Vista. Would this be why it's not coming up with the same windows?
Anyway, here's what came up;
Control panel > "Network + Internet Connection" from there I could go into> "Wireless Connections" then into >"Properties". There it does not have what you have, but,just says "Connect using" then, in a box it says "Intel(R) PRO/ Wireless 2200BG Network connection. No mention of TCP/IP!
I did come across something that says the wireless connection is working properly, along the way.
Sorry if I sound dumb. It could be cos I am.

Any more advice?
Trish
