2Wire the dreaded word here!
Been there done that one. Are you running hard wired or the newer WiFi?
With the hard wire RJ33 phone line type you would look under Network adapters in the device manager for the PC Port item. That's with the old dsl type set up. The Home Portal hub would connect through the nic card for the host pc.
Bad news for Home Portal is the old software will not install even on the 32bit Vista let alone get anywhere on 7. The PC Port drivers
will only work on the 32bit Windows being the outdated 98, 2000, XP only never having seen any Vista drivers written.
A fast change of ISP came here last year when not able to get online with the 64bit beta! Bye Bye 2Wire! The HP software simply would not install even on the 32bit making that obsolete just for the host which still runs XP! No thanks! This is what you are looking at with a look at what you are running there the 64bit Home Premium?!
