Since a couple of month ago my server started to drop the network after around 15-20 days uptime. The server works like a charm while it is up, and is no big issue when im at home, since a restart solves the problem for another 15-20 days.

 

Still it is a frustrating issue..

 

I have googled the problem and havent found a good solution, i know the network controller is the onboard sky2 and that might be the problem. I have 2 ports and have tried both, bonded and not bonded.

 

I have also tried to see if there is something else that can cause the problem, i did a reconfigure of the network, and changed a couple of devices (switch + router), but the problem still exist.

 

I havent bought a new network card (yet) because i'm not 100% sure thats the problem.

 

Here is the log when the network problem occurs (diagnostics file attached aswell):
