My husband built a new computer for us (first time) and we installed Vista Home Premium 64bit OEM yesterday. It will not connect to the internet. He has tried connecting just through the modem, as well as through our router (Linksys WRT54G) with an ethernet cable. No connection either way, but the IP address is showing 192... etc...

Vista says "unidentified network" and "access; local only"

Has anyone had this problem? We were on the phone w/ Comcast for an hour last night, and we don't think it's a problem with them.

Any help is greatly appreciated - we're at our wits end, since we have no other support options.
