Hello.
We are running several sites with 8540 WLC and a mix of legacy and up to date AP's
Currently we run 8.3.143.0 AireOS on all WLC's but we have had issues, especially with the 2800 ap's and false radar detection.
According to the release notes we shouldn't have these issues, but reallity prevails.
Here is a summary of our issues today:
In the TAC recommended releses 8.5.161.0 should be the obvious choice, but only one site has a range of access points that supports 8.5.xxx. Also I have seen some really nasty bug notices lately on the 8.5.161.0 release.
In the light of above information; should anyone recommend 8.5.161.0 relese, or should the 8.3.150.0 be sufficient?
I cannot find anything in the 8.3.150.0 regarding false radar detection that isn't fixed already in 8.3.143.0...
...but 8.5.161.0 does have two bug IDs (CSCvf38154, CSCvf21657) that isn't noted in the 8.3.150.0 release notes.
Any suggestion and advice are welcome.
Sincere Regards

Hi Leo.
Any reason why you haven't upgraded?
From which code did you upgrade to 8.5.135.0?
I have learnt from others that 8.5.xxx train will improve roaming performance compared with 8.3.xxx
What is your inpu?t

Thanks.
Appreciate the advice.
We will consider that or wait until a new maintenance release is release för 8.5 train. You are aware of this field notice? https://www.cisco.com/c/en/us/support/docs/field-notices/705/fn70577.html
Other nastyness; CSCvg83600, CSCvt47413, CSCvt98797 et cetera.
Of course there are an Escalation release available for 8.5 as well, but the latest notifications suggest more work is needen on 8.5...

Hi Scott.
Thank you for your insights. Actually I have gotten feedback that the oldest legacy ap's have been replaced, so now we have a mix of mostly 2800. with a lower count of 2700 and 3500 series access points on the controllers in question. These are all supported in 8.5 tree. I am pretty sure that our best candidate is 8.5.161.0 or if a later maintenance release is provided. It will surely improve roaming performance if feedback from collegues are correct. Or should you recommend that we make a request for the 8.5.161.x Escalation release?

No, that's not correct. 3500 is supported up to 8.4.X.X.
