Not sure if this is somehow just me or if anyone else has 10.4.1.2 running and seeing this. I did not have this issue when running 10.4.1.1 but not sure if it is just the firmware or Aruba Central that is causing this.
For the last couple weeks (10.4.1.1 -> 10.4.1.2) we have had reports of wireless issues. I found that our APs were selecting invalid channels on the 6Ghz range. This was causing very poor TX to clients and very high retries/errors.
I have manually set the channels for the 6Ghz on all of our APs and that has resolved our issue.
Our setup:
AP655 - 10.4.1.2
Mobility GW(Controllers) - 9240 x2 - 10.4.1.2
Switches are cx6300/8325/4100i - 3 tier network
Here is some details/logs:
AP is using channel 85S and has >90% retry rate
The valid channels for 6Ghz 160Mhz are 5S, 37S, 69S, 101S, 133S, 165S, 197S - 85S is not a valid channel.
Logs from a different AP but having the same issue. This AP was using channel 21S which is invalid:

The last log I posted is why I think this might be related to Aruba Central and maybe not the firmware upgrade.
AM: provision from central
pri_chan:21
band:3
chan_bw:4
I do not have any documentation on this so this is just an assumption but this is what I think the above means:
Primary Channel - 21
Wireless Band - 3 (6Ghz) - I assume 1=2.4Ghz and 2=5Ghz
Channel Bandwidth - 4 (160Mhz) - I assume 1=20Mhz, 2=40Mhz, 3=80Mhz and 4=160Mhz
If we put all of the above together we get 6Ghz 21S and that is not a valid channel.
Also - I am not going to open a ticket with TAC - I am frustrated enough and have wasted tons of time troubleshooting this. I am behind on work and do not have the time or emotional energy to deal with Aruba TAC.
