What should I look into troubleshoot file?
There is full config of the device so for the obvious reasons I cannot add it here.
Answering the question, port WAN is not working no matter I do, before reboot, after reboot, during reboot, when reconnect utp cable, with new utp cable, with hand made utp cable. Simply it seams to be dead.
My question is - is it anything in such troubleshoot file or other log which can confirm my worries?
