My setup: 2106 controller with 4.2.205 firmware, 4x: ap1030 radio. We presently add 2x: Air-rm1252g-a-k9. My problem: I'm not able to activated the 40 mhz bonding channel on the Ap1252. I always receive the message: "Slot is not enabled or customised is not enabled." I tried using cli..and same error happen! I Upgrade the radio to be able to use the 300 mbps bandwith!! not a succes until now!
