Re: GA-MA785GMT-UD2H 8111c disconnect problem
It looks like some people are recommending to use the rt8169 driver from this postviewtopic.php?f=17&t=1525
I have the 8111dl driver and on my MD-GD80 MSI P55 motherboard and experiance the same frustration as you. At times I go for weeks with no issue, other times it is several times a week. I will be trying this out soon, as I am getting tired of having to fix this all the time.
Please post back if you try this and it works!
