LAN adapter not working

October 1, 2011 at 14:33:52
Specs: Windows 7, intel q6600
I'm running WINDOWS 7 . My onboard Ethernet adapter stopped working, which I use to connect to the internet, the ruter is working as I have a laptop that connects to the router wirelessly. now i try plugging in any Ethernet cable, it still shows red X on my local area connection. Here's what i did to solve it:

uninstalled adapter, reinstalled the drivers
restarted 10 times
swapped Ethernet cables (verified cables work on other computers)
unplugged, replugged back in.
System restore

device manager shows good signs that the device is working. I have a good feeling it does, just something in the software maybe that I'm missing. i hope somebody has had this problem before and could point the way to an answer. thanks.

Additional Details
THE DEVICE LOOKS LIKE IT WORKS, ACCORDING TO THE SOFTWARE. BUT EVERY TIME I PLUG IN A CABLE, IT DOESN'T WANT TO FLICKER ANY SIGN OF CHANGE. I'VE USED GOOD CABLES FROM GOOD SOURCES. MAYBE SOMETHING I'M MISSING, REGISTRY? SERVICES? BIOS? IT DOES SEEM TO BE HARDWARE RELATED TO ME. NOT SURE IF THERE IS SOME CONFIG FOR THAT.

Motherboard is EVGA 680sli

Hi
Is your device on other end of cable powered on. X sign normnall appears in case of faulty cable or Ethernet port going faulty for either of devices on both ends.

Try a cross over cable connection from this PC to your network port of your laptop. See for sign of network coonnection on both devices ( pc and laptop ) , either they should show connected or waiting sign to rec an ip address from dhcp server. Try giving manual ip address of same subnet on both devices , by giving manual ip address , these X should disappear and they should show connected and they should be able to ping also to each other .

Please diagnose the same and update .

how do you manually give them IP addresses? What do you mean cross over connection?

Oh, yes the router is powered.

I did do the below:

-Try disableing Upnp on your router,
Its broke on some causes random disconnects
-Disable ECN proticle
1. open a CMD prompt AS ADMINISTRATOR
2. type "netsh"
3. type "int tcp set global ecncapability=disabled"

to try & get round a connecting to a game server problem, I then then did the same but put enabled, & that was when the LAN port stopped responding, (the light on the port stopped flickering)
