Dear All,
Our WLC 4402 and 46 1130AG Access points in LWAPP mode have been working flawlesly for the past few years, but suddenly this week some access points have not been working (but the rest are fine). They are correctly registered on the WLC, but if anyone tries to connect they get an authentication failrue and the WLC logs the following. Nothing on the WLC has changed, the only thing that's changed on the network is a new firewall (the WIFI network is one of the subnets) but that shouldn't affect whether users can connect to the WIFI network. Anyone have any clues as to what's going on?

What kind of authentication i being used on SSID that the clients connect to? If RADIUS server is involved, can you verify if it shows any logs pointing to auth failure?
