I've created a WLAN group called "Disabled", with no WLANs active. Then, under the AP Group you can select the WLAN Group that radios go into - just select the Disabled WLAN Group you created.
This solution does't really work.
Seems like APs still have radio enabled.
Checked event logs and get this. see below:
2014/02/10 20:22:37 Low AP[RAP_0541] detects interference on radio [11g/n] and switches from channel [9] to channel [1].
2014/02/10 20:12:37 Low AP[RAP_0541] detects interference on radio [11g/n] and switches from channel [9] to channel [11].
2014/02/10 20:02:37 Low AP[RAP_0541] detects interference on radio [11g/n] and switches from channel [9] to channel [11].
2014/02/10 19:52:37 Low AP[RAP_0541] detects interference on radio [11g/n] and switches from channel [9] to channel [11].
2014/02/10 19:42:36 Low AP[RAP_0541] detects interference on radio [11g/n] and switches from channel [9] to channel [1].
2014/02/10 19:32:36 Low AP[RAP_0541] detects interference on radio [11g/n] and switches from channel [9] to channel [11].
2014/02/10 19:22:36 Low AP[RAP_0541] detects interference on radio [11g/n] and switches from channel [9] to channel [1].
So in my opinion AP still creates unnecessary interference
