We have a logon problem with CP after upgraded to 6.1.2.4. The logon will fail to load most of the time.
After various checking, we found that client can associate with AP and got a IP address and have the
logon role assigned. By ping test over the default gateway (L2 pass though setup) and the controller's
interface IP, There are serious packet loss from 25% to 75% and some time completely failure. When
ping is completely failure, reboot of AP it associate can help to improve the packet loss rate to 50% or
lower right after the reboot.
We tried to remove BW contract and increase Max Session (from 20 increase to 200) of the logon role
but have no improvement. Once the client authenticated, network access will improve. The problem
seems didn't affect WPA/WPA2 SSID and widely spread over our 1100+ AP. The level of failure seems
various from AP to AP and also various with time.
Anyone have that problem too? Can someone share your finding if you have such problem too?
We had upgrade from 3.4 to 6.1.2.1 then 6.1.2.2 and 6.1.2.2_30153. We didn't try 6.1.2.3.
May be the problem also appear in 6.1.2.3.
