Suddenly I became unable to receive anything at home over the net. In
the past I've corrected this either with repowering or shutting down
XP - home (as opposed to my typical hibernation). But not this time :
( I'm a heavy PC user and applications programmer, but a real IP and
connectivity moron, so bear with me. And I know this is long, but I'm
trying to get you everything relevant.

I have Time-Warner cable (a.k.a. Road Runner) configured in this order
wall
Cable Modem
Linksys router (non wireless)
PC with XP
Sygate Personal Firewall and Windows (XP) firewall
Internet Explorer 6

Vonage supplied the router. I use VOIP. This is the only thing that
works! No web. No Messenger. No anything else that uses the Net.

I've tried overnight powerdowns, even plug away from wall; full XP
shutdowns; clicking on "automatically detect settings" under LAN
settings, and back off again; bypassed the router; while bypassing
tried the other ethernet cable instead; disabled both firewalls.

WHAT I SUSPECT TELLS THE MOST:

Checking the Sygate traffic log, almost 100% of the trickle of traffic
shows 192.168.15.100 (or .255). It SHOULD show things like the Google
IP and everywhere else I try to browse. But there's not even an
ATTEMPT to connect to Google shown. (And if some firewall rule was
blocking, that should have shown on the log.)

The only remote host address among dozens of 192.168.15.xxx log
entries is 10.8.0.1. However, sadly, I can't even backtrace that with
Sygate Firewall, 'cuz I can't get to the Net (:

Watching the firewall's activity graph, while clicking "hide broadcast
traffic," I see blips from my webmail checker - but only outgoing, and
zero bytes incoming. And when Roadrunner support tried remote
diagnosis, I could see both incoming AND outgoing blips.

ROADRUNNER support says I have a bad NIC card. Is this all I can try?!
Sounds bogus to me. What about the blips on the Firewall graph?

Finally, if I uncheck "hide broadcast traffic" I can see continuous
movement on the activity graph. Tiny, but something. This is like
"noise" that just buzzes along, regardless of whether I have an
application attempting traffic.

What can I try now?

Youve opened a command promp window and pinged the google ip?
ping 64.233.167.104

If no response then;
I would disable both Firewalls, if you actually have both enabled this can
cause conflicts
Unplug (pwr) both the router and modem
Leave for 5 mins, pwr up the modem then router, and test

Two different firewalls active may cause a problem. Try turning off the
Windows firewall.

I've run both firewalls together for years. Yet for diagnosis, I shut
both off, but to no avail. I've unplugged the power strip for PC &
cable modem & router and repowered all 3 the next morning. No good.

If you are getting VOIP and Vonage is working, then the problem is not
your connection to the net. It lies between your router and the
computer, or in the computer network settings.

Way to go, NoConsequence! It turned out to be hardware. A new NIC
solved it. Whoda thunkit?!

Thanks to EACH of you for your time and effort in offering suggestions.
