I was doing a favor for a neighbor whom just went wireless on a Linky 802.11b. The cards went in the pc's just fine, all was happy. On a Tosihba laptop, she had an onboard lan which was already factory configured and ready to use. When I plugged in the pcima card, XP recongnized and configured it, loaded it's drivers, and placed like 6 network connections in the task bar. When I went to my networking properties, there was a network bridge in the local network side, and a wireless conection, her username connection, and a local area connection. It wouldn't surf, and it wouldn't share. It also said I had more than one device using the same IP, and disabled the address. So I went into the device manager and disabled all the networking devices except the wireless card, and then removed the wirless connection and the username connection from the network bridge and all was well again. So what is this "network bridge" and how is it supposed to work? Any advantages to using this thing properly?
