The silent reboot bug was hitting us. We were having APs reboot all over
campus with unpredictable frequency. We had to upgrade. It wasn't a
question for us.

I’ve been running various beta versions of MR5 in production and have
had no problems.
If you have the new AP’s 1810/1850/2800/3800 then you should
absolutely upgrade as it offers huge improvements across the board for
those WAPs, including some fixes for client-side bugs.

I just went through the release notes, am struggling with whether to
try to rush an upgrade during this week while Spring Break has campus
slower than normal. We’ve been refreshingly stable on MR4, and not
experiencing any of the resolved caveats so I’m leaning towards
waiting until end of semester. Does anyone know of anything that rises
to the level of a stand-out bug that is so common and heinous that it
drives this to “should update immediately” status?

Bruce,
Engineering version 8.2.150.4 is, to my knowledge, what will become
8.2 MR5. This is the code I’ve been running on and so far rock solid.

Is the engineering code you are running, the same MR5 code that is due
to be released soon?

Short answer is it is a bug. A “Kernel Panic”. AP loses its mind.
Very prevalent on the new stuff, to a much lesser degree affects
“older” stuff.
Sometimes the reset fixes it. Sometimes not. We doubled down on
1810’s and 2802’s. Bugs galore. Which are actively being fixed-to be
fair.
We are running on engineering code and HUGE improvements have been
made. Soon, I think/hope, it will be rock solid.

We are currently running a handful of 5508s with 8.0.133.0 and have
been stable for some time with around 400 APs and upwards of 1.5k
clients. We also run a half dozen 5520s with 8.2.141.0 and they have
been running solid with around 1k APs each and upwards of 10k clients.
We do not however run anything but 2600, 3600, 2700 and 3700 APs.
The only issue I have seen that I don’t understand well yet is related
to some APs losing the minds during network interruptions. The APs
will appear up from CDP neighbor information, but will have lost their
name and will not connect to their configured primary or secondary
controllers. A power cycle will often recover the AP, but not always.
I believe that issue started with 8.2.
Thank you.
Ken

points whose minimum supported version is 8.2.110.0. I was
looking to the group for their recommendations on a stable version
of code which will support our new 2802i access points.
