Ethernet not working - Lenovo x200

[simonmason]

My Ethernet on my Lenovo x200 just stopped working. It's hooked to a gigabit ethernet network in my home which then passes through a Verizon FIOS 10/100 router.

I checked the driver and it is up to date (Intel 82567LM).
It shows loaded and no errors in device manager.
IPCONFIG shows IP 169.254.230.196.

Windows networking shows Unidentified Network on Local Area Connection with No Network Access.

Deleted adaptor from device manager and reinstalled it with no luck.

Disable adaptor and re-enable - goes through the identifying process and then ends with No Network Access.

IPCONFIG /RELEASE and /RENEW results in the same thing.

Ran Lenovo Hardware tests - all hardware pass - network tests of course fail.

Run Windows Network Troubleshooter and it tells me there is an issue on the router side.

I am running DHCP. Other clients on the network are connecting fine. I tried manually configuring the IP on this machine and it took the new IP address but still no Internet access.

Perhaps related - Tereno Tunneling Pseudo-Interface was showing with yellow exclamation mark in Device Manager. I don't know if this was always like this. I found some trouble-shooting steps for this online - going into regedit and turning HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\SERVICES\TCPIP6\PARAMETERS dword to 0. (It was all f's). Now Tereno Tunneling Pseudo-Interface is now gone from device manager but I don't think this is relevant as I am not using IP6 (I don't think).

Bad network adaptor?

Set your Internet Protocol (TCP/IP) to automatically obtain an IP.
The IP should then be in the 192.168.x.x range or 10.10.x.x range, to show it comes from the router.
The IP you show is probably your provider's IP.

Um, no. The IP range 169.254.*.* are link-local addresses:

In IPv4[1], they are normally only used to assign IP addresses to network interfaces when no external, stateful mechanism of address configuration exists, such as the Dynamic Host Configuration Protocol (DHCP) or when another primary configuration method has failed.

http://en.wikipedia.org/wiki/Link-local_address

In other words, your ethernet adapter get such an address because it failed to retrieve an address assigned by the router via DHCP.

What happens if you set up a static IP (in the same subnet as the router), default gateway and DNS servers on your computer?
