How to force 802.11ax only and disable any other protocols

How to disable any other protocols and enable 802.11ax only for ipq807x series devices?

removed, might have been incorrect.

It will still advertise i.e a/n/ac/ax. I believe this option is more like support up to ax, and not only ax.

Last I looked it wasn't in the GUI, but you can manually add it to an AP config:

option require_mode 'ax'

(I haven't actually verified this works as intended, but it causes no errors. My home setup is AX by design rather than AP policy: Wi-Fi hwmode values seems to be out-dated)

Yeah, that was my point. In Luci it will change htmode.

However, I'm curious if you can add multiple modes, like 'axn' or something to require_mode.

require_mode sets the minimum, you can’t set multiple protocols. You pick one and everything above that (and including) is allowed.
If by “axn” you were referring to ax and n on 2.4ghz, then just set require mode to “n”.
If you meant ax and n, but not ac, on 5ghz, that isn’t possible AFAIK.


Seems at least you can set require_mode to ac:

@lantis1008 My uninformed guess would be ac works for 802.11n on 2,4 GHz as well, since the spec for 2,4 GHz wasn't updated from 802.11n to 802.11ac. Or am I wrong?

I’m not certain, I would need to try it.
A quick look at the hostapd code suggest it might do nothing. There are lots of flags like

if (hapd->iconf->ieee80211ac && hapd->iconf->require_vht)

So because ac shouldn’t be set on 2.4 this might just cancel out?

I haven’t got an AP configured I could try it with at the moment.
