Thanx for reply.
No changes have been made since first set up. Inet Connection still available on the XP boot up on same PC, I did a clean install on a partion on laptop so am at a loss.
I know no changes were made, but it is possible that Win7 couldn't find any drivers for your wireless card in the first place. Check device Manager to make sure the wireless card is enabled and working correctly.
To do that, open the start menu, type "device", and click "Device Manager" in the list of results. Under the heading of "Network Adapters" (I think), right-click your wireless network card, and click "Properties". Let us know what it says in the "Device Status" box.
