I have a problem that is way past my ability.
I use a D-Link DIR 655N Router.
It was purchased expressly for it's firewall and to be able to use it's other features in the near future.
I have XP Pro w/SP2 hooked throught the router to cable broadband.
Before I bought the router, I was hooked directly to the cable modem and operated without a problem.
I need to be able to use this pc, sometimes, without the router.
But when I hook up the cable modem to the pc, I have no internet connection anymore.
I had the cable company on the phone for over an hour. They feel it's a problem with the pc. Possibly the ethernet card.
I updated the drivers for Realtek RTL8139/810x Fast Ethernet NIC and that doesn't help.
But when I hook up to the router it works fine.
I looked at the ip address while the router wasn't hooked up. It's 169.254.253.214 which cable support said is not a working address.
Any help would be greatly appreciated.
