Dear Sturm

We were running the code 8.0.121 on our 5508 controllers. However, one of the 
controllers started rebooting every two or three days after the reading week. 
The cisco engineer told us that the controller hit a bug CSCuw52341 (WLC crash 
with RRM task RRM-CLNT-5_0 is due to a bug CSCuw52341), and suggested us to 
upgrade to an engineer code (version 8.1.131.13) to fix this bug. We have run 
this code on all of our 5508 controllers for about two weeks, and did not have 
any problem. Furthermore, if you plan to do the hyperlocation with the AC wave 
two Aps, you’d better upgrade to the code 8.1 or higher.

Have a nice day.

Yours,​​​​​

What is the preferred/stable release for a Cisco WLC 5508?
I’m planning on updating this summer.

AP’s 2800,1810 and 3800 series support is required.
