I have the WRT54G router, and am using it with a at&t 6550G wireless pci card. Computer B can connect to my router, and I can see on the router that it is connected, but the router does not send a single packet over to computer B. In windows, I get the "Limited or no connectivity" warning. And if i try to renew the ip, it doesn't work, even though the router shows computer b connected, and with the assigned IP i gave it. And I can't ping either the ip i gave it, or the ip computer b is showing to have. Thanks for any help.
