Is ~2% early failures in a batch of APs typical, or should I be
concerned about a manufacturing defect or some unknown external factor?
We're small enough that we've never before bought more than 15 or 20 new
APs at once, so haven't previously had any early failures. However,
we've just upgraded our full wifi system, and I have two dead out of 105
APs after a couple weeks. Not DOA, but they ran each ran for several
days, and then went of line.
They're obviously still under warranty, so all I can do is wait and see
how widespread this problem will be, but I'm not sure how much to worry!
Hopefully after failures during initial burn-in, the rest of the APs
will all last a long time.
A few basic Google attempts didn't yield stats for initial and
longer-term enterprise AP failure rates, so I'm curious about what you
bigger schools experience, and how much variation there is by model and
vendor. Are 3x3 and ac radios more failure prone than simpler, perhaps
cooler running, gear? I generally expect some APs to fail every once in
a while, but as far as I know, no vendor has a reputation of being much
better or worse than the rest.
If those of you who've been buying thousands of APs for years have data
you can share, we may get at least an anecdotal feel for typical failure
rates, and perhaps a sense of variation by vendor and product.
