I have a Linksys wireless router working fine with two Mac laptops. When my Windows XP laptop tries to get on the network at the same time, it connect to the network but is never assigned an IP address and won't access the internet. If the Macs disconnect from the network, the XP laptop can connect and get the internet fine. I have never seen this problem before and have no idea what is the cause. Any ideas?
