I have an HP 6152n w/ Vista home that the motherboard and power supply were fried in a power outage. The local Fry's said that the p5q-em motherboard was a compatable replacement. I replaced the power supply and the motherboard. Everything seems to be working fine except for the Realtek LAN that comes with the board. I get "local access only" and "unidentified network". I am direct wired to a Vonage router then to a Comcast cable modem. If I try to setup a broadband connection, it asks for a userid/passwords. Comcast does not use or require userid/password and they told me to call Microsoft (yeah, sure!). I've tried numerous ipconfig commands, turned off/reset router and modems, changing duplex settings, winsock resets, removed and reinstalled drivers, downloaded current driver (on this XP Pro computer which has wireless access to the same router/modem w/ NO problem), followed numerous rabbit trails on the net, but nothing seems to work. Vista says that the network settings are correct. I tried switching different cat5 connections between different direct wired items (xbox), nothing. The 'activity' led does NOT light up, the Speed LED does. If I disconnect the wire from the router, this light goes out. Does anyone have any ideas? Follow up... I installed the Express Gateway software that came with the mobo, rebooted and enable EG in Bios.. I CAN access the internet through Express Gateway!!!, but if I start VISTA, I still get limited or no access. So this seems to be a VISTA problem - but I have searched and searched the web and cannot find a fix. ANY SUGGESTIONS ARE GREATLY APPRECIATED!!!! I'm reaching the end of my limited tech abilities!
