Wdtv live hub can't obtain IP address?

Just bought a wireless adapter for my hub, updated the firnware with it connected directly to the modem, and then moved it to the other room and plugged up the adapter.  Before I updated, it looked like everything was working fine, but now that I have the latest update, it won’t obtain an IP address.  Any suggestions?

Are you sure it’s connecting to the wireless network at all?

As in, your adapter is supported and functioning?
