limited or no connectivity in VISTA


I am reposting this from my post in Network and internet forums because
of no response. I'm getting desperate and am having a tech person come
in tomorroww morning at $105per hr. to try and fix this problem.....

I have an HP 6152n desktop w/ Vista home that the motherboard and power
supply were fried in a power outage. The local Fry's said that an ASUS
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 NIC driver (on this XP Pro laptop and another wireless XP pro
laptop which has wireless access to the same router/modem w/ NO
problem), followed numerous rabbit trails on the net, but nothing seems
to work. Ran repair numerous times and tired every option with Vistas'
diagnose/repair/reset screen. Vista says that the network settings are
correct. I tried switching different cat5 connections between different
direct wired items (xbox-which connects just fine), nothing. The
'activity' led on the NIC does NOT light up, the Speed LED does. If I
disconnect the cat5 wire to the router, the Speed LED goes out. Does
anyone have any ideas? Follow up... I installed the Express Gateway
software (allows internet access for Skype without the OS being booted
up) that came with the mobo, rebooted and enable EG in Bios.. I CAN
access the internet through Express Gateway!!!, but if I start VISTA OS,
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! :cry: I have also since tried the following:
Disabled ipv6 as well a qos packed sched, and link layer topology
(suggested by other sites that I've found with similar problems). Still
no access.:sa:
