As for Netgear, you can use an AP to be a client to a pc via the USB or crossover cable. In which case both the computer and the AP need an ip address(AP 1st of course if your using dhcp).

As for bridging, the AP bridges to another AP via MAC address.. it can be any other 802.11b AP, doesn't need to be Netgear.
