AP 3660 does not change to Non DFS channels

[Emre_Kurtman]

Hi, We have AP 3660 with ANT-21 external antennas. We can not select any Non-DFS channels in the drop-down list of channels in the AP Radio settings. And the AP is frequently changing its channel due to Radar interference. How can we change the AP's channels to Non-DFS channels?

So there are no solutions I can think of other than using only 2.4 Ghz band if the AP is constantly changing its channel because of radar interference?

No sir, not in Turkey for either the 3660 or 3856e.

[Emre_Kurtman]

So any different antenna models I can use on 3660 or should we change it to 3865e to use those channels?

ANT-21 channels supported and certified for use in Turkey are.... 100,104, 108, 112, 116, 132,136, 140 (all DFS) no certification in Turkey outdoor mode for 36-161
