[Solved] 802.11ax worse than 802.11ac with mt76 driver?

About 802.11r issues:

Personally I've faced these issues when trying to enable 802.11r with Archer C6 v3 (Mediatek MT7621). I've never managed to make it work with Apple devices after a lot of efforts trying to make it work. So i gave up. After I've upgraed to AX6S (Mediatek MT7622) I've never tried to re-enable 802.11r. Basically both Android/Samsung and Apple devices are roaming pretty well across 4 different APs without 802.11r.
