I've been using a linksys wireless router for about 6 months. It's worked fine, but all of a sudden the router doesn't recognize one of the computers. I reinstalled the drivers and entered all the ip addresses, gateway, subnets, dns entries, etc. statically becuase it wouldn't work dynamincally.

The computer I'm using is running linux and hooked to the router via an ethernet cable. This is working fine. However, the machine that doesn't work is WindowsXP (it's my fathers). I can ping the router, this computer and the dns entries from that computer, but that is the only way that computer receives packets from the router. Otherwise it keeps sending packets out, and doesn't receive any back. The strange thing is that the wireless network icon on the Windows computer says the connection is excellent. I know this is not linux specific, but I was wondering if anyone thinks there might be something wrong with the wireless card on the windows machine, because several other laptops running windows can get run on the network and the router recognizes them. Thanks for any help.

try changing out the card, also, try using a wired connection to the router on the laptop and see if that works.

I am a complete newbie and the comment could be way off, but could someone have turned on some firewall in the machine so it blocks all incoming traffic?
