Can't connect to the internet

Dimension 4600 - xp pro - cable modem. Can't connect to the internet. I've
done a clean install of xp pro on a clean drive with nothing else on there.
Same problem. Went from AO7 bios to AO6 - same problem. Installed a stand
alone NIC - same problem. Did all the ipconfig stuff - makes no difference.
Modem is good because it works flawlessly on another box. Tech support said
to disconnect power from the modem for two hours to let the bios flush. Did
that - no difference. tcp/ip is set to allow dns selection of the ip. I
don't &%^&% know! Anyone out there have this problem, and what did you do
to resolve it?
TIA, RJ

 

Have you checked your Firewall settings?

Way back in the old days, 1999 or so, some companies like Time Warner
did have MAC address caching and it did cause a ton of headaches. Did
you ever have success getting the dell to use the connection? Or is
this a new attempt to get it connected? If so, asking people who use
the same net provider might help.

Otherwise, break it down to the pieces. ipconfig and ping are your
best friends. Make sure you have an ip address. Make sure you have
a default gateway. Ping your nic, gateway. traceroute some upstream
company and see what happens.

 

Sure sounds like you have ICS enabled (or another firewall installed). If
you nave either, try disabling it for the time being.

The cable system records the MAC address of the device attached to the
modem. the order you turn them on is important. Try to:

- Power everything off and wait a minute (where do they get 2 hours??)
- Power on the modem and wait until you are on-line and have stable lights
- Power on the computer

If that doesn't work, try

- Power everything off and wait a minute
- Power on the computer
- Power on the modem and wait until you are on-line and have stable lights

 

This is a blanket statement that is no longer accurate. Comcast,
for one, no longer [if they ever did] cares about MAC addresses
"of device attached to the modem". They use the cable modem's
MAC address, whether you've got the one they provided, or have
bought and recorded your own with them.
