Do I read correct that Central reports firmware 8.6 but if you check on the AP it is in 8.9? That is something support will need to have a look at because it indicates there is a communication mismatch between Central and your APs.
1) Yes, you can upgrade. In general, following the recommended version makes sense. If I'm correct that is 8.6.0.9, so at least upgrade to that from 8.6.0.2 if there is no reason to stick on 8.6.0.2. Before upgrading to 8.9 make sure that you know why you want to do that (other than see if it fixes the issue). New features or new AP support are good reasons to go to such a new version. TAC can advise in here, and I wonder if upgrading to 8.6.0.9 has been discussed as it sounds the most logical step. What you experience, I have seen a few times with early firmware versions for the AP 505.
2) Yes, disabling 11ax for the SSID in Central should do the trick. You can check the actual setting from the CLI: show ap bss-table.

Dear Experts,
One of our customer is using 505 with Aruba Central. Firmware is 8.6.0.2_73853. Client is facing random disconnects and sometimes their wireless is stuck, means there is no activity and they have to connect/disconnect multiple times to get back on.
Aruba TAC is already on it but so far no improvement. I am reaching out to community to advise if someone faced a similar issue and might know the problem? the current version is 8.9 but central is showing 8.6. In addition to above query can someone advise on below 2 points also
1) From Aruba central, can i upgrade to 8.9 (even though central is recommending 8.6)
2) How to disable High Efficiency under SSID? is it done by simply disabling 11ax (its currently disabled)?
