I upgraded last week my pc to i7 3770K,DZ77GA-70K and Corsair Vengeance CMZ16GX3M4X1600C9.Updated to lastest bios (045).Did a fresh install on windows 7 sp1+all updates installed all newest drivers from intel site.After few hiccups and some reset bios default settings everything worked perfectly after 2-3 days while the pc was on the lan/network lost the connection and started identifying non stop network - stoping - starting identifying again and this loop over and over again.Once i disabled the lan and re-enabled it straight away everything fixxed for couple of days.Then appeared after one day and now today again.Once i enabled and disabled everything seemed to worked perfect.To mention the 2-3 times from the 4 times the problem appeared it happened when i launched or i was playing diablo 3.Router was working fine since i had net with my phone and my laptop.Is there anyone with a similar problem like this?Seems like a hardware prob,driver,bios problem or some software collision problem like diablo 3/comodo chrome or ms essential?
Thank you in advance for your time.
I haven't tried turning off to be honest the second port in bios will try it cause tbh in my case is useless as well.For now I re-installed the latest driver but this time using Run as Admin and will test it for 2-3 days to see if it was simply a bad case of driver installation.Also changed the Link Speed from Configuration from auto-detect to manual speed of my lan to see if it helps.If doesn't i will also try disabling the second lan and i will report back.
Seems it was a bad install of driver 4 days now non stop rock solid network connection.If anyone has a similar problem Install latest Driver again with Run As Admin and and then change Link Speed from configuration of the network from auto detect to the manual speed of the lan that did the trick for me.
For 2 weeks i had my mobo on the Secondary LAN Intel 82574 (since this was my Local Area Connection 1 automatically after format didn't know which one was primary and i assumed this one was) and i had this problem putting Manual Speed and reinstalling driver as admin made it to disconnect rarely but still disconnecting(from 1-2 days to 3-5 - but again fixing it was 5sec work but still annoying hiccup).Yesterday once i disconnected once again i did what dislikeyou did and disabled secondary LAN and reconnected to Intel(R) 82579V and so far seems OK i will for sure report back if everything worked OK for a bit longer but this smells like driver or bios problem rather than hardware.
PS.Anyone from the intel staff if they can acknowledge this as known issue of driver/bios would be good (we have long patience as long as we hear some confirmation of an issue/bug or even they are looking into it cause the mobo is rock solid and performs excellent its bad to have and little but annoying problem).

Same issues here. However I can´t fix it just by disabling that NIC and enabling it again. After trying that several times the Systems freezese completely. Only a restart fixes it but just for a couple of hours in the best case.
For now a made an ALB-Group of both NICs to ensure that I don´t get kicked out of RDP-Session and other Online-Activities.
