windows can't connect internet 169 IP

October 5, 2010 at 11:43:41
Specs: Windows 7, Opteron / 2GB
I had a motherboard go out and took the computer to the local shop to have it replaced. After it was replaced, I could no longer connect to the internet. (This was under XP 64). Here are the relevant details....

* Intenet is via wi-fi. I use a local router to plug in my desktop computer. It is my desktop that can not connect.
* I can connect with my laptop by plugging it into the same router I plug my desktop into.
* I get an IP address that starts with 169 on my desktop when I try to connect.
* With my desktop, I've plugged the router into both the ethernet jacks on the back. No connection with either.
* I have tried to connect via a wireless plug and that does not connect either. (Other computers here can connect via wireless directly with a plug or via a wireless router.)
* Thought it might be an XP issue so replaced with Windows 7. Did not fix the problem.
* If I take the computer to the repair shop, they can easily connect to the internet simply by plugging in the ethernet cable in the back or by using my little wi-fi plug. (So this means it seems localized to my location and my computer simply isn't playing nice with the network somehow.)

That's about it....

Any assistance would be greatly appreciated!

169 means it can't get to a dhcp server

if builtin lan card is it enabled in the bios?

Post a ipconfig /all from the pc for review

Here is the full ipconfig / all for my system. I really appreciate the help, having this computer down has really set me back.

It is odd how the computer will work on the network at the computer store but not here and my laptop will work on the network here without a problem.

Thanks again!

Appears you have two ethernet interfaces in this pc. Try the other port [though you did try that already].

It appears the pc nic is not getting an answer to its dhcp request.
What is your routers lan ip?
Put a ip address in statically in your tcp/ip properties one up from the gateway number. So if you have 192.168.1.1 for router give the pc xxx.xxx.1.2
Put 1.2 for dns. See if you get connected now.

Post a ipconfig /all from the working laptop for review also. Thx

BTW all FF's for physical address doesn't look right.

For example my physical address is
Physical Address. . . . . . . . . : 00-18-D2-AF-E4-46

Your router may have mac filtering enabled and when you changed motherboards you changed mac address of the NIC.

I don't know of SOHO routers with MAC address filtering on LAN site, but on wireless.

The original poster should always write the last response !!!
Let us know, if the problem is solved !!!

My D-Link DI624+ has mac filtering for all LAN side connections. I don't use it but it does not discriminate between wired or wireless. Simply has settings to allow or block computers with listed mac address.

At the D-Link DI624+, MAC address filtering did definately not filter the MAC addresses on LAN, only on WLAN.

That does not make sense paulsep. A mac filter or dhcp address reservation is all inclusive to the lan and does not differenciate between what part of the lan; wired vs wireless

if you look at page 27 of the DI-624 you will see mac filter on lan does not differenciate between wired or wireless since both are the "lan".

http://www.scribd.com/doc/2091490/D...

all the routers I have owned that supported mac filtering did so on all lan access.

But we digress from the OP's issue.
