im trying to fix a laptop for my cousin. its a compaq presario v4000. the problem im having is that it wont connect to a network. it doesnt matter whos network(doesnt work on his or mine). also, neither the wireless or regular ethernet cable work. ive trying using both and i get the same result. i have the wireless turned on, the computer recognizes it. when i search for networks in range, it says "windows cannot configure this wireless connection" if i try to repair the connection, it fails saying that it cannot be completed since it cant connect to a network. when i connect an ethernet cable, it says that windows cannot configure the connection. ive tried doing a system restore but that doesnt help. im at a loss as to whats wrong. any ideas? thanks.
