Infamous 169.254.x.y/DCHP problem...

November 10, 2010 at 08:40:10
Specs: Windows XP
I'm running XP Pro and I'm connected directly to the cable modem (no network)

When I try /release and then ipconfig /renew I get:

"An error occurred while renewing interface Local Area Connection : unable to con
tact your DHCP server. Request has timed out."

I've also tried updating NIC drivers, modem firmware, winsock driver using microsoft's fix-it. I've tried powercycling the modem and restarting the computer with different combinations...

I can only think to get a new NIC or install a router (which I understand may circumvent the problem but doesn't fix it)

Here is what I get when I ipconfig /all:

Do the lights light up on both your nic and the modem when you plug in?
You have used this cable successfully in the past?
Have you called your isp to have them check the modem?

pc or a laptop? can you get a friend with a laptop to come over and see if they can connect?

If you can't get an ip from the modem a router will be no different.

The PC I'm using now is connecting to the same modem. It's when I use the other PC I get the above problems.

*shakes head*

OK well that isn't surprising. Yes you need to buy a router if you want both connected at the same time.

It would appear the ISP has logged your pcs mac address [physical address in a ipconfig /all]. You would need to clone this mac to the other pc and/or the routers wan interface when you get a router for either of these to work.
