Hog 3 network adapter lost

Hello,

Our Hog 3 loses its network adapter after it has been powered on for some time. If I switch it on it normally works for some time, maybe hours. Once it did loose connection to DP during rehearsal. Easiest way to reproduce this fault is to reboot after desk has been on for few hours. After adapter is lost it won´t be found again before long cooling time, but on the next day it starts up normally again.

In controlpanel network tab it shows that mac adress is 00 00 00 00 00 00, ip adress is 0.0.0.0, link state is down, hog net adapter is grayed and says eth0. Also Rx&Tx packets is 0.

Full install of 3.2.6 has been done but no change in behaviour.

I have understood that network adapter is integrated in motherboard. Is there anything else to check before ordering new motherboard?

thanks,
Harri
