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?
