I set up wireless network using my daughter's laptop, an iBook G4, and a Netgear DG834G router. I then connected a Netgear Wg111v2 wireless adaptor to my windows XP desktop. After couple of months of wire-free surfing, the signal strength to the desktop began to slow, then drop, and now I can't get a signal at all. But the laptop, which has an Airport card inside, connects with no problems at all.
I've moved the router to other phone points (including one inches from the PC!), reinstalled the adaptor (several times), tried another adaptor, and been through my PC settings with the very nice people at Netgear Support. But all without success. The PC will try and detect the network. When it does detect it, the signal strength is too low to connect. Usually though, it does not detect it.
I set up the network using the laptop rather than the PC because it came with an ethernet cable which connected to the router, whereas the PC doesn't have an ethernet point.
Does anyone have any idea what could have happened?
