I have 2 pc's on my network. One pc is connected to the router with a cable and the other pc is wireless. I´m having problems logging on to forums and other secure sites on my wireless pc. The Signal is Excellent. I've tried to turn the windows firewall off but that didn´t work. I´m not using any other Firewalls. I can´t figure out what the problem is. Any Ideas?? My Setup: "SpeedTouch 545" router "SpeedTouch 120" Wireless USB Adapter "Windows XP Pro w/sp2"
