I have a netgear router mr814v2 which is connected to a cable modem. I have a mac connected wirelessly, a lop top connected with a netgear pc card and an apple i touch that connects. I have recently moved my desk top windows xp computer to a new location and installed a netgear adapter wg 111v3. The computer worked well for a few weeks then went off line. I cannot seem to get this one computer to go online. The netgear smart wizard set up is configured to a wep security which is known. The wizard finds the router, but the adapter states not connected , firewalled, then the wizard loses signal and resets to a red screen. I have aol spyware installed as well as mcafee and windows firewalls. Am i being locked out bya firewall??
