I have an issue with 2 new AP 505 they cannot join 2 already running AP 207
1st it gave me image is different and after upgrading I get: AP register fail because of regulatory domain mismatch.
both 207 and 505 are same EG domain
the difference is the DRT, every time I upgrade the 505 DRT to 1.0_87798 it reverts back to old DRT after AP restart.
I can't run both of them in the same network.
