Hi Everyone.
I Deploy a lot of Aruba AP-505 and found the same issue. I config the DNS A record for aruba-master for AP can find Controller when connect to different network. When testing with another campus AP ( AP-207) it's can find Controller by DNS perfectly at any network it connect. But when connect the AP-505, we can see it's not try to
resolution DNS ( we get the wireshark and see not thing about ADP of DNS or DHCP option ), but if the AP-505 connect to the same network with controller it's query the DNS and find controller or if when the AP boot to instant, i convert it to Campus AP and then re-provision it to ADP mode and connect to another network it can query DNS. Please help me with this issue.
