I run a Linksys Router WR45G without issue. I'm hardwired and 3 other rigs use wireless adapters. One rig is recently acting up. The signal strength is excellent and is turned on for approx. 5-10 minutes and then automatically firewalls itself even though it's still turned on with excellent signal.
I manually turn off the firewall but the rig still can't surf or get a signal. I've been through XP Support without avail.
I've also reset the modem and router to no avail.
I don't have these issues with the other wireless rigs.
