I have seen 2 out of around 100 suddenly exhibit the ADI Communications Failure
after about a month in service, neither was on the serial number list. So a 2
day burn-in may help but you won’t be bullet-proof. We’ve only seen it on 5
GHz SMs, but we use a lot more 5 GHz than 3.65 GHz, and no 2.4 GHz. No
apparent correlation with any environmental conditions like hot or stormy
weather that could have precipitated it.
Worst case will be it fails intermittently and the new customer just thinks
your service is really unreliable. One of the 2 failures we saw was
intermittent, rebooting for several hours, then registered for several hours,
then rebooting again, no rhyme or reason. At least if it fails hard, they will
call.

We had 9 failures in 50 we ordered, those were not listed in the unit serial
numbers.
What we are doing now is running radios in the office for at least two days
before we send out and we are seeing these failures in the office.
Even after doing that today we had one fail which was 1 hr drive from the
office and it was new customer too, installed last week. This gives us bad
reputation and cost us lot too.
So whatever the root cause mentioned in the email, if it was identified but did
not include the batch we got, so something is not adding up still.
I really hope cambium gets to the bottom of these quickly.

Just a bump... was this ever sorted out? Contained to just one batch of 5.8
radios as listed? I know I've seen reports in other frequencies but seemed
less widespread? No mention from anyone in a while... Just want to know
before our next order...

I wanted to get this out to everyone before the weekend. We found the root
cause and identified the affected units by serial number.
