Cubieboard2 after boot is visible on network, sometimes not

Hi

 

If i boot my cubieboard2, sometimes it's visible on network, and reachable, sometimes not at all. After that, it isn't changes. No problem with the LAN cable, i've tried two. Also the speedtest shows the maximum bandwidths in both directions (~92 mbit/sec).

 

The system boots always, as i see from logs.

 

Here is from the log:  

sudo cat /var/log/messages | grep ether

2 times it was reachable from network (2nd, and 4th boot), 2 times not. Anyone sees something?

Where is armbianmonitor -u ? Showing only errors is not sufficient.

 

I don't have this board to reproduce (also impossible due to unknown kernel u-boot version) nor its on the supported list ... you can try to install older versions of u-boot too see if that helps?
