Has anyone moved from a 2860ac to 2862ac and if so have you found the wifi performance noticeably better please?

I have moved from a 2860ac to a 2862ac - running the latest firmware.

I have had a myriad of wifi issues, but they have been on both routers.
I haven't noticed any significant performance boost.

I think it is down to honing and tweaking the precise settings for my environment, as I also have 2 x AP910c's running the latest firmware.
Trying to provide the best 'ac' 5GHz coverage I can throughout my property.

Strangely, I had a lot less issues when I turned down the WiFi power.

Re turning down the power - what caused you to try that? Are there any diagnostic apps I can use to see if the power is too high?

I've kept my power to 100% on both frequencies and all APs, with no issues.
Taking the router's wireless out of the equation has sorted everything for me - disable wireless on router completely.

Not ideal, so I am awaiting a firmware update that will hopefully match the wireless settings of the Router with the APs or visa versa

I have both routers, and have found the 2860 gets much better results than the 2862 in the 2ghz range. I have tried both with the stock antennas and with the 7db gain antennas. The 5ghz range is similar for both.
