I own RB951 for ~4 years, working like charm. Few months ago I finally fixed wires so my desktop is on metallic, running without any problem. 5 days ago I upgraded to 6.47.4 and was fine until earlier today - all of the sudden wired connection was gone - without any action on the router. After long troubleshooting, downgrading, loading old and older configurations backup, upgrading back to 6.47.4, I was able to use only ether2-master port. As far as I can tell, 2 and remaining ones are configured in the same way; before that malfunction, no change at all (firewall, dhcp,...).
While I'm kind of happy that I can use at least ether2, I'd love to know what might happening. Router is not in dusty environment with good ventilation, temperatures (hand checked) seems just normal.. perhaps it's just dying?
Below is part of the log file, with zero activity on my side - just looking for answers in other threads on different computer.
