Wireless Access

Hi 

I have aruba 3400 controller. suddenly it is not saving anything, for example i am trying to provision a AP to a group but when i change it and apply it is not working . i have logged in to the console of the ap and change the group. please help

What version AOS are you running ? Is this only happening with one AP?

Have you tried using another browser ?

You could also try provisioning through the controller CLI:

tried in another browser still the same and it is for all AP. And i am not able to add wlan. i have to configure it through cli. the wlan wizard is not working. i

Check the logs and see what might be failing 

show log system 50

do you also provision your APs via a wizard? because the wizards have been known to act strange. i would try to clear the cache and try again and if it keep failing with other browsers / browser versions.
