hi dhiraj,

thanks posting here.

>& sometime it's showing "attempting authenticate". wlc showing authentication request denied & nps not showing log.

what os running on these clients affected issue ? mentioned using tls method in wireless connection guess peap-eap-tls .are using self-issued certificate or purchased third party ? how many certificate been installed on client side ? have set connection request policy on nps server ?

as workaround , first deselect option “enabled fast reconnect” in peap properties in wireless profile on client  , see if can reproduce :

 

thanks.
