Common problem, "cable unplugged" error windows 7

Hello dear community

Now i've tried to fix this error myself for countless of days, this quite common problem.

The error is following: My computer now and then doesnt recognize that i've got a ethernet cable plugged in to my computer.
The internet work all times on all of the other 3 computers in the home network.

OS: win 7
NIC: intel r 82566dc-2 gigabit network connection

I've tried to disable IPV6 adress, updated drivers and some other stuff, And when I tried the option to change the link/duplex from auto to fixed it worked. Sometimes it worked at 10mb, then it lost connection to the cable and I changed it to 100/ 1 gig and it work again. And when 100/1gig didnt work i changed back to 10 aso. This worked for about 1-2 weeks. Then suddenly it couldnt find the cable in neither of the options.
So I tried the good old plugg out modem, router + computer and let it be offline for some hours and then put it on again. I tried this several times each day for a week (changed to all varies of duplex each time). Then suddenly it worked again, for 5 hours, then it died AGAIN.
Now ive been cut from the internet for some days on my desktop computer again. Needless to say im getting pretty frustrated.

So after this time I give up, I need you expert help. Do you have any clue what to do?

Best wishes
Simon

From Dell or Intel? The reason I ask is Intel normally has newer drivers for Intel hardware.

Also, did you ever set it up to auto negotiate the speed rather than set it for 10 or 100/1GB speed?

Also, can you get to a command prompt, type "ipconfig /all > info.txt" (without the quotes)
and upload info.txt to this forum?

Yes I tried the auto also.

I downloaded the drivers from Intel. I've tried out 3 different drivers, just incase the new ones got baby errors.

I'll post the ipconfig /all, just gonna usb it over to this one. Brb!

Okay, so first you do not have a wireless adapter? At least according to your text.

And, as you indicated, media is disconnected for your NIC.

We can try resetting the winsock protocol:

Start, Run, CMD to open a command promptright click on cmd and select "Run as Administrator"

Reset TCP/IP stack to installation defaults. netsh int ip reset reset.log

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reboot the machine.
It May require 2-3 reboots
