The same thing happens if you change it on the controller? I assume it changes to AP? The WCS is just reporting what the controller is telling it if this is the case you have an issue on the controller and we do need the controller version.
It has been deployed for just over 2 weeks now and was fine until this weekend. Saturday evening and now this morning it has changed its name from what I have supplied through the WLC back to the MAC based name.
Running in HREAP mode.
I have some 16 AP all running off this controller and so far this is the only AP that appears to be having this weird issue.
I do 95% of my configuration through the gui of the WLC and the other 5% through the gui of WCS.
