Weird issue.
AP 1832i----switch(no trunk)-----DMVPN--WAN--DMVPN--WLC5520 8.5.151.0
Sometimes PSK Auth process fails with message "wrong PSK" on Device.
Sometimes it works. Seems like there are "timeslots", when it works - and when it does not work.
Seems like some MTU / TCP MSS issue where auth-packets are fragmented?
Very annoying as never knowing if client can authenticate or not.
When he tries some minutes later, successful.
When he is authenticated, connection is OK. Its the auth process that fails.
No pattern when it occurs.
Ideas?
I opened TAC with "debug client <macadress>" and "show tech".
