We had 12 Aruba APs fail last year out of 7,500 access points.   Our numbers, 
however, are rapidly going up.

More data points would be helpful, particularly from schools with equipment 
under-represented above. If anyone else is using Xirrus, I’d like to know if 
they are seeing as high a failure rate as we are.

I’ll update the spreadsheet as more responses are received. Thanks for your

RE: [WIRELESS-LAN] Access Point Failure Rate

[T. Shayne Ghere]

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 aren’t in the best environment for electronics.

Around 550 Cisco AP’s. Had 1 dead autonomous 1131 and 2 damaged 2602’s from

Pretty happy with that.

Cisco AP’s Almost 1900 now ranging from 1131-37002 series

Never had enough issues to record anything. So anecdotal
Perhaps 1 DOA every 400 AP’s
Sitting at about 10 failures for installed AP’s the last 2 years. But about 7 
of that would be the +10 year old 1131 models

So gone pretty well for us

Ignoring of course damaged AP’s. mostly water leaks

RE: [WIRELESS-LAN] Access Point Failure Rate

[Jason Cook]

Having said that we pulled a 3702i AP the other day that was performing 
terribly on 5ghz interface. But only 1 user in the area was reporting issues 
and mostly because he had some large file transfer requirements.. not a high 
density area at all either
So perhaps there’s a few issues out there not yet found ☺

Tried reboots, config clears, different channels etc while on site. Nothing 
fixed it. Yet to re-test.

Cisco AP’s Almost 1900 now ranging from 1131-37002 series

Never had enough issues to record anything. So anecdotal
Perhaps 1 DOA every 400 AP’s
Sitting at about 10 failures for installed AP’s the last 2 years. But about 7 
of that would be the +10 year old 1131 models

So gone pretty well for us

Ignoring of course damaged AP’s. mostly water leaks

Re: [WIRELESS-LAN] Access Point Failure Rate

[Harry Rauch]

We only have about 330 APs at the moment but have had two failures. One 
from an airhandler drip pan overflowing right into the AP and the other 
was from a lightning strike on an external bridge AP. We use Ruckus for 
the last 5 years. We have 1800+ students in dorms on campus.
