Trying to get a friend's PC working with Comcast high speed
internet at home via cable modem. Having some strange software
issue with the PC.

I installed a known, working NetGear NIC and related drivers in
the Gateway PC that is running Windows XP SP1. (I had to install
this NIC because the onboard Intel NIC with latest drivers was
"flapping" - would continuously go between "enabled" and
"disconnected" states).

Windows shows the status of the NetGear LAN Connection as
"Enabled" and the link light LED is green and showing activity.
However, the NIC statistics show that packets are being
transmitted but "0" packets are being received. I had Ethereal
running on the PC and it shows the DHCP Discover packets being
transmitted (reflected in statistics) and other DHCP broadcasts
for other MAC addresses.

I plugged 2 other PCs into the cable modem and both obtained IP
addresses right away. Therefore I know that Comcast service is
working properly and providing addresses via DHCP.

I know this is strange but my guess is that there is some
software that is installed on the PC that is preventing packets
from being received by the NIC. I tried uninstalling AOL,
Norton AV, and Spy Sweeper software and still saw the problem.
I also tried enabling/disabling the windows firewall.

At this point I've run out of ideas and asking for help from
anyone out there that has seen this problem before or may have
other ideas.

Thanks, Z


When you plugged the other computers into the cable modem, did you
use the same cable? This sounds like it might be a bad cable.

Yes, I used the same cable. So I know the cable is good.

At this point, I'm out of clues. As a despiration measure, you might
try the LSP fix program. Check out the following website and see if
this tool might fix your problem... (couldn't hurt)...
