Sorry if this is the wrong section... Does anyone know why we can't connect to our network with a linksys wusb54g USB 802.11g card? My dad purchased this for my sister and immediatly the card didnt work on her computer so he installed it on his - it broke the machine. AND the network. I'm now on dial up waiting for a reason why this card broke our network - anyone else have trouble with this/know how to fix it?
