I've had this board for about 6 months, and i've started having this problem about 3 weeks ago, basically the intel I211 would stop working randomly, and tries to reconnect itself for a couple of seconds (and after a while it does reconnect).

Rebooting the pc doesn't fix the problem, and it persists after changing between windows and linux. The cable works perfectly fine with another pc, so that's not a problem.

Running dmesg on linux gives me this 3 lines which repeat themselves over and over:
igb 0000:04:00.0 enp4s0: igb: enp4s0 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX/TX
igb 0000:04:00.0: exceed max 2 second
igb 0000:04:00.0 enp4s0: igb: enp4s0 NIC Link is Down

I've tried following the fix from Sixthsense from this [URL=http://forum.asrock.com/forum_posts.asp?TID=12050&KW=ethernet&title=x570-gaming-phantom-4-no-ethernet-detected-win-10]thread[/URL], and it actually worked for a couple of minutes, before disconnecting again.

I tried updating BIOS from 1.30 to 2.60, and it started having the same problem after a couple of days.

I'm not sure what else to try, any help is appreciated.
