Name. That. Problem

[JoeHz]

Got a machine that periodically loses its ability to see anything. Log file when it happens is certainly indicative of something wrong, but what?

If it matters, it is using a wired connection to an AIMesh Node (an RT-AC86U) that is itself configured as a wired backhaul. As expected, the main router (An RT-AX86U_Pro) reports it as a wired connection, as if it was plugged into a switch. I suspect this rules out all sorts of possible things.

RT-AC68U DHCPREQUEST(br0) DHCPACK(br0) ???

I've just completely defaulted my RT-AC68U due to numerous disconnection issues with any firmware since 3004-378-4585. I've also used the Merlin 380.57 version and getting some strange log events, something that I've not seen before and wonder what it is thats causing it. I also have a RT-N66U...
