I am work on a customer's computer that is running xp not sure of what SP. i installed a linksys internal nic. got everything installed, able to find the network using the linksys software. able to connect but i never receive any packets. can send but not receive. i had to manually put the ip in or it would connect but with limitations. There is also something else that's odd, when i tried to connect to the network using the windows software it always come back none found. its a at&t 2wire modem with wep 64 bit. i have been able to connect other computers wireless and have been able to connect from the same room.
