Looks like 802.11ac is defined here: for 5GHz only
Not sure why that is actually.

@systemcrash any idea?

I saw something about 11.a on the mailing list yesterday and today which could be related.

In any case, I don't think this has anything to do with luci. If it did, you'd see it in the queued changes before applying. @lessload has not provided any such information, so I suspect this is in a lower layer (uci or wireless system).

[Ramon00]

come to think of it, I guess VHT20 is not allowed on 2.4 GHz...

[dannil]

VHT is defined in IEEE 802.11ac-2013 which only encompasses the 5 GHz band, the 2,4 GHz specification in 802.11ac is inherited from IEEE_802.11n-2009 which specified it's channels as HT. The question is therefore moot since it isn't a valid configuration anyway.

See #12904.
(if ipq40xx uses ath10k as the 2.4 wifi driver, it is supported by this PR)
