  • 1.  Only one channel showing in 5GHz

    Hi,

    We upgraded our controllers to 6.4.4.9. We also changed regulatory domain settings to support 5 GHz channels 149,153,157,161. 

     

    We noticed that 90% of APs are on channel 161, , few on 149 and none on 153 and 157. Many of the adjacent APs were on the same channel. When I checked channel interference it was very low (Between 0 to 10%). But this does not llook right as ARM should adjust channel numbers. 

    What could be the possible reason?

    We also disabled 40 MHz and 80 MHz and only allow 20 MHz for both 2.4 and 5 GHz.

    Make sure that "Client Aware" is unchecked in the ARM profile.  Client Aware will not allow an AP to change channels if there is active client activity.
