Ken,

For the AP’s that have lost their name and require a reboot. Would you check 
the following for me?

On WLC or PI, what do the problematic WAPs report as their backup software 
version? Typically, it should be the same as the “backup image” under 
commands->config boot on the controller. If it’s instead an older version e.g. 
7.1.x, let me know.

It’s circumstantial at this point, but I’ve noticed a pattern.

·         AP’s that exhibit the problem tend to also fail AP Image Pre-download 
(Download Primary) during code upgrades. If you make a note of these failures, 
those WAPs are more likely to have mental issues.

·         AP’s that exhibit the problem have very old (what shipped on it) code 
in the backup location e.g. 7.x

·         Issuing a AP Image Pre-download, Download Backup to these AP’s will 
replace the old code in the backup location.

·         Once the old backup image is updated, AP pre-download (Primary) now 
works during code upgrades, and the AP’s seem to stop losing their minds.

Subject: Re: [WIRELESS-LAN] Cisco WLC code recommendations

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

We are currently running version 8.0.133.0 on our Cisco 5508 controllers, as 
our current access points are primarily 3500s and 3600s. However we have 
recently purchased a batch of 2802i access 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.
