Hi  @RMitev 

Thank you for you kindly feedback, I have forwarded these info to our software engineers. 

It may not be solved in a short time, but please take concern on our firmware updating.

ER707-M2, WAN is "WAN/LAN3" and gets IP via DHCPC.

After restart of the router, in the system log, the interface shows as "unknown" instead of "WAN/LAN3" (lines 25-22)

After manually reconnecting the WAN (lines 21-18) the interface shows as "WAN/LAN3" (lines 16-17)
