Clients can authenticate succesful, work for some time, until they get an authentication failure, reason 19, followed by reason 20. WLAN has to be disabled and again enabled on the client and it's working again unti it come's again to the authentication failures. What do these failures mean? And how can these be resolved?
Thanks, Roland
