CCR-1036-8G-2+ Crashing!

troy · Sun Oct 01, 2017 6:03 pm

Router started crashing this past week. Tried to update firmware to 6.38.7 and 6.40.3. During download, router crashed. Tried again, download finished, router rebooted, but would not update. Tried 3 more times, router crashed part way through download.

Replacement on the way, but will be Tuesday before it gets here. Any suggestions on upgrading and/or stabilizing this thing?

Thanks!

Do you monitor / graph the power levels of the device?

Sounds to me like it's the PSU failing... Quite a few people suffer from PSU issues on the CCRs, despite MT claiming nothing wrong, problem fixed, new PSU, etc...

Eeks!

It went into a very rapid death spiral... rebooting every few hours to the point where it would reboot after 30-40 seconds of uptime. Tried a PSU from a 1009, but no joy. Replaced it with the 1009 for now.

Finally got my hands on the unit...

The PSU is pushing 24.2V. The router itself will not power up. Very weak sounding beep every few seconds.

Serial console gives me the "Press any key.." message repeatedly. Some times I can get to the menu, sometimes I can't.

Guess it's a goner. Anyone know if it's worth trying to refurb?
