Unable to connect to DHCP server

Hello, I've recently replaced the motherboard, cpu and ram in my computer and done a fresh install of windows xp sp2.

The motherboard is an ASUS M4A79 with an onboard realtek RTL8168/8111 ethernet port, running the latest (and only) driver.

I am using a router connected to a cable modem, but I have also connected the computer directly to the modem with the same results.

I am able to ping the localhost, and ASUS tech support feels the mobo isn't damaged.

About the best I can get is a partial connection, with the device status reporting "Limited or no connectivity." The Ipconfig /renew command returns the error: "An error occurred while renewing interface Local Area Connection 3: unable to contact your DHCP server. Request has timed out. "

Was able to ping yahoo once using IP #s instead of ping www.yahoo.com, but it only returned 1 of 4 pings then timed out.

Things I have tried so far:
- Different cables
- Uninstalling/Reinstalling network card driver
- netsh command
- ipconfig release/renew
- manually inputting IP, gateway, etc, no joy


I have also installed a spare wireless NIC to troubleshoot and was unable to get any connectivity there as well, even in totally unsecured mode. I'm able to detect multiple wireless networks in range, too.

I've never had this much difficulty with networking before outside of linux. Any help would be sincerely appreciated!

Here's my ipconfig return:

Hi Tony, tried that but exact same ipconfig output and limited connectivity.

I tried manual settings again, specifying everything I could including DNS suffixes etc. This enabled me to ping the other machine on my router, but still no internet connectivity.

I'm really not sure what's holding it back here...

 

Well I'm posting from the new computer, so something must have clicked.

One thing I did was go thru the D-Link router's setup, and manually input the MAC address for my new motherboard. I'm pretty sure this is what was blocking the system from talking to the router properly.
