For the record, my “40” failures includes for the past calendar year, and
includes ALL non-functioning APs. We have had very few (none that I can think
of but don’t want to exclude the possibility) of DOA’s.

Sorry Jason, should have added more. The 700 below is a cisco install.
Cheers,

Thanks for your replies so far. I’ve collected your data so far:
[cid:4DAAA493-FF21-414A-ACBA-C5C01B1B5069]
Brand Failure Rate per Year
Cisco 0.5%
Aruba 0.3%
Aerohive0.4%
Ruckus 0.6%
Juniper 0.7%
Extreme 0.0%
Xirrus 5.2%
School Brand APs TermFailed Attrition/Year
We have roughly 600 Cisco AP’s. It’s a mix of the 1142 and 3702i’s, but
getting ready to triple that amount with all new Wave2 AP’s.
Our failure rate over the past 5 years is between 7-10 total. Four were
from a lightning strike, but the others were the 1142N model and are in
areas that
Syracuse- since 2002, probably an aggregate of 16-18K APs through life cycle
replacements of Cisco variety (fat and thin). AP failures? Likely statistical
zero, like maybe 10 through the years. (Excellent AP build offset by horrific
code issues at times and NMS chronic pain.)
In our branches,
Denison University
Aruba Wireless
APs: 1047
Mostly AP 225s
RMAs in 2015-16: 5
** 3 of these RMAs were from the cover falling off of the AP for no good
reason. I believe this is a defect on that model. The APs were still
functional though.
** The other 2 were APs that went into a continuous reboot
Had 6 Cisco 1131s go this year but they were all old and due for replacement
(7+ years old) and they all died after failing to come back up after power
issues in buildings (power going up and down several times over a few hours,
they powered by a mixture of poe switches and poe injectors).
Around 550 Cisco AP’s. Had 1 dead autonomous 1131 and 2 damaged 2602’s from
waterleaks in the last 5 years.
Pretty happy with that.
