I have a Gateway desktop computer that will not keep a wireless signal. All other computers work wirelessly. I have used 3 different wireless adapters. It will install the adapter, get the wireless signal, and then in a few minutes drop the signal and then in a few minutes connect again. Isn't there a utility that fixes the networking portion of XP? I had one but I can't find it or remember the name. I really don't want to reinstall Windows.
