@Kevin_Z Unfortunately it does not seem to resolve the issue. I did save the log according to debug instruction, where should I submit?

I've had the C1200 v2 (US) for the last few years, and for the most part it's been rock solid.  The last few months, though, it's started suffering from the random reboot issue.  Updating to the latest stable firmware didn't help.  Updating to the beta version in the pinned solution fixed the random reboots, but broke uPnP for me, and made my online games no longer playable.  The router settings would say uPnP was working but my games couldn't connect to their servers.  Reverting to the latest publised stable version made my games playable again, but reintroduced the random reboot issue.  I'm getting multiple random reboots every day for the last several months.  I have cooling fans under the router 24/7 and the transmit power is set to medium, but that doesn't seem to help at all.

I updated with the beta firmware as directed for the C9 V5 and it is still rebooting multiple times per day.

The game I play the most, and that I've had the most problems with using the beta firmware, is Warframe.  It requires UDP ports 4950 and 4955 open to communicate to matchmaking servers.  Normally, under the stable firmware, the router settings page for uPnP reports that the ports are being forwarded, and the game works fine.  Switching to the beta firmware, the router would still report that the ports were being forwarded, but inside the game, an error would pop up about opening the ports, and the game wouldn't connect to other players.  The game settings, firewall settings, AV settings, DNS settings, everything was the same as before, with just the switch to the beta firmware being the only change, so I guessed it was the beta firmware that was responsible.  Rebooting the router would help temporarily, some of the time, but always the ports would stop communicating after an hour or so.

The other day, after I posted my message, I actually turned the WiFi transmit power down to low, and turned up to max the cooling fans I have the router resting on top of, and that seems to have done away with the reboots on the non-beta firmware.  If it starts rebooting again, though, I'll try updating to the beta firmware again while using your recommended DNS settings to see how that works, and I'll let you know at that time if anything's different with regars to the uPnP issue I was having before.

How do I do that?

Hi, sorry to hear that.

 

Can you pelase confirm if you have disabled the NAT boost on the C9? If not, give it a go and confirm, thanks.
