A 169 address means the DHCP server is not responding, or you are not on the network at all. Perhaps move closer to the access point?

I just tried to leave AIM connected once again. Signed on @ 5:30, came back to check @ 7:00, and it was disconnected. The exact IP address is: 169.254.0.136

David–I’ve had my laptop about 4 feet away from the cable modem + router (it’s a Motorola Wireless Surfboard Gateway SBG900), ever since we got wireless.
