I was assured today that the issue isn't the hardware. Evidently this
issue can be solved with an upcoming software upgrade.
Time will tell.

We have some APs that have uptime over 60 days but many reboot every

Cambium on this via an open ticket and sending them all of the
information they request and nobody has said oh gosh that is bad
hardware RMA it. So, we're just going around and around. We'll end
up just replacing it and hoping they will take it back because
obviously this is bad. We are running 14.x per their request. We saw
this on 13.x as well.

Joe, that is seriously bad. I see watchdog resets and a few stack
dumps, but uptime on 450 APs is typically 2-4 weeks, despite the
recent cold weather, in fact I don�t think it has been more common
than it was last summer. I have not gone to 14.x though, everything
is still on 13.2.
So either you have a bad unit, or 14.x is making it much worse. If
everyone was seeing resets every few minutes or hours, I think there
would be villagers with torches and pitchforks outside Cambium HQ.
Brian from FVI does have a thread on the Cambium Community about this.
FWIW, I have one 450i 900 MHz which necessarily is on 14.1, and it
does not appear to be having watchdog resets. Lightly loaded
however, just 2 subs.

We see a ton of reboots on the 450 platform as well. It's getting
pretty frustrating simply because this is such a long term issue.
One of my APs has rebooted 195 times (now running 14.1.2). They are
saying we should replace the AP but it is unclear if we can RMA it or
not. We do have an open ticket.

Extremely frustrating and causing real customer complaints.

Over two years we have been seeing random reboot. We were told over
and over again you are the only one. Then few people started
reporting.
But cambium never could get bottom of the problems for two years
so, I gave up on cambium fixing this random reboot. We stop
calling them about it.
As the new versions of the software has come out over two years we
have see the frequency of the problem reduce but not gone away.

So who else is having reboot-o-rama with 450�s?

Although replacing 100 450 AP's is cheaper than ePMP. :-/

Hello Cambium,
At the MidWest-IX launch party last night, several of us
Indiana WISPs compared notes on the �cold weather�
problems we are seeing with ePMPs. It was very interesting
to learn we are experience identical problems across the
spectrum.
We all understand this is a DRAM issue with certain units
you have identified. We also understand the firmware RC
that has been made available to fix this short term.
The bottom line is we are very frustrated and grow tired
of dealing with it.
Our concern is simple. If your software fix �degrades�
the performance of the product or triggers other issues,
as it has been suggested, we would prefer a full recall
and replacement program immediately.
If the suggestion that the fix will degrade the product
performance is inaccurate and not cause other issues, I
would like for this to be made public.
Thank you,
