Latest stable WLC version

[lldemeyer]

Hello,

I have all my WLC's at V4.0.217 and they seem to be running fine. Now I need a more recent version to support non-expiring Guest accounts on my anchor controller. SO I do need minimum a V4.1.sth or higher . What is the most recent GD or most stable version ?

Second question: if I only upgrade the anchor controller to let say V4.1.185 will the remote controllers still at V4.0.217 have no problems with this ?

Thanks in advance.

I'm running 5.0 code on 6 WiSM's with around 1200 access points. So far so good as far as reliability goes. WCS running 5.0 code has some quirks but nothing major so far.

I suggest you keep all controllers at the same SW revision. As noted in another thread there are mobility issues when mixing code versions on controllers.

You may have issues with guest anchor. See last post on this thread.

Also, there may be a WebAuth Guest anchor bug in 5.0
