E6750 Core 2
8800 GT
4 gigs ram
XP pro
GABYTE GA-P35-DS3L
No anti-virus or software firewalls :fou:

Just built this system this weekend:

It seems that randomly(usually after a restart) the LAN on my mobo will revert back to a factory IP of some kind(seen below). The connection no longer seems to recognize the router. When I cant get a connection and it doesn't work it reads:


autoconfiguration ip address:169.254.46.201
subnet 255.255.0.0
(no default gateway)


I tried uninstalling drivers, using factory cd drivers, upgrading newer drivers, everything... The way I "fix it": Uninstall Network adapter under device drivers, use gigabyte upgraded drivers to unistall AGAIN, Remove Lan cable, Restart, Install new Drivers, Plug cable back in, cross fingers.

Once I do that I get issued a good IP from router and all is well.

Anyone have any idea what is going on?? I've been spending more time under my desk then anything since I put this thing together.

EDIT: This is a brand new system, new windows, hard drive, mobo, ram, everything. I used to have old computer set up in same spot with same LAN line and I never had a problem. I was using a different version of windows xp Home. Also, did a ram test and everything checks out. Played Team Fortress 2 on max settings for a few hours and it ran well locked at 60fps.

Try renewing till you get a good IP address, write it down, and maybe try assigning that as a static IP.

well its hard to think of why something like thi would happen

normally you would recieve an error like "warning limited connection" it could be an array of factors depending on your network setup...

im going to assume the following things,

you have one computer connected to one Router using a CAT 5 cable..

the router has DHCP set up, and your internet connection is set up through the router. if this is the case plugging in the network cable should do it, if it doesnt have you checked the cable? is there any 90 degree bends? does the green light on the router and network card come on? is the router and the network card on the same subnet? normally 255.255.255.0 OR 255.255.0.0

i forgot to add, goto

start > connect to > show all connections > then right click your LAN connection, > Properties > select TCP/IP from list > Properties > then set up your own I.P in the correct range, and set the subnet to the same as your router.

If you can't get an IP from the router, I'd try a new cable, this one could have a kink in the line. What router do ou have?

This is called an APIPA (Automatic Private Internet Protocol Addressing) address.

When you get an address like this, it means that your computer is looking for a DHCP server (such as your router, or cable modem), and not finding one. So...the fix is to either properly configure a DHCP server (you may need help with this), or to not use DHCP at all, and set up your network using static IPs. It's hard to picture something on your client causing this.

Do you have any other computers on the network? Do they experience any problems?
