I probably read the Release Notes too fast and assumed that it was a
fix. I just re-read them and I only see what you do. So it appears
that there was no 'bug fix' for this issue. In the Cambium forum, Matt
M noted that there may be a Maintenance release to address this. He did
not state an ETA. I would assume that us submitting support tickets
<shudder> would help them get closer to squashing the bug.

Brian, is it your understanding that 13.4 was supposed to cure or help
the watchdog resets? I don't see anything in the release notes other
than the log entry for user initiated resets.
I wish I could detect a pattern or cause-effect relationship which APs
exhibit this and which rarely or never do.

For us, we rolled back the affected AP's to 13.2 and they are back to
their normal routine (once in a while reboots). I replaced one of them
and brought back here to test. I'll know more after we collect graph
data and submit a ticket with Cambium.

So what's the current status on this? Is it better to upgrade to
13.4, or stay on 13.2? And do you have to upgrade both APs and SMs?
And was 13.4 supposed to fix a watchdog reset problem? Or just
create a different event log entry for user initiated reboots?
Watchdog resets are a big problem, it used to be just gamers and VoIP
users, but now everyone bitches if their video stream buffers. Or
their smartphone switches to using mobile data, or their webcam has
gaps. And it's worse with DFS or LBT.

We have been seeing this across 200+ AP's
It's getting truly annoying. Cambium tech support has helpful
suggestions like'just put them in free run'. Um.... Thanks for the
help, but no.

Last week we rolled out 13.4 to 450 AP's after testing in-house for
a while. While running 13.2 we would see an AP here or there reboot
on occasion by itself. The only message in the Event Log mentions
Watchdog Reset. This is one of the bugs that Cambium noted was
fixed in the 13.4 release notes.
Since we upgraded the network to 13.4 we are now seeing at least 4
AP's out there rebooting several times per day. On one of these
AP's we are also seeing SM's (all 17 registered) reboot along with
the AP. The site has UPS backup so I know it's not a power grid
problem. I am planning to roll the affected AP's back to 13.2 this
evening.
Anyone else having Watchdog issues with the 13.4 release?
