FS#762 - TP-Link WR1043ND v4: Network on switch fails at random
User who did this - Adrian Draus (r43k3n)

How should I know? It's dead both WAN and LAn and I've seen more people complain about this issue.

By "cannot reach" I mean I can't log into the router from SSH or ping the router from using SSH while connected though Ethernet cable. I also cannot reach other devices connected though switch. They don't get IP or any other other info from router. Switching packets while in progress (like copping files over Windows network) is still working even after the failure so the basic switch capabilities are working.

sysconfig and dmesg are clean I posted them before somewhere on forum. No one (including me) find there anything and I mean anything. Not a single mention about this state.

I can't ping the router while connected using Ethernet at all.
