cap ax with old capsman on wi-fi ac

Hello, can I turn off wifi 6 on cap ax and use wi-fi ac like old devices?

And connect cap ax to to old capsman with wi-fi ac ?

No. Ax devices require wifiwave2 driver, which in turn is not compatible with legacy capsman.

Well, technically you can disable 802.11ax support on wifiwave2 driven APs, but I guess this isn’t what you’re after.

Can i disable 802.11ax driver and use 802.11ac driver (on cap_ax) as Cap_ac device ? How i can did it ?

Impossible.
