WOW , I create temp profile and provision.
I change RAP MTU from 1200 to 1500 , still has a problem
I add SAP MTU from nothing to 1500, now SSL web working ! problem solved !
However, I am not sure my configuration is correct, this number 1500 I assume from some answer in aruba community, not sure it is a right thing. Currently , RAP MTU 1200, SAP MTU = 1500.
And if I apply this configuration to AP105 802.11N, is it will create a problem?
