802.11s channel width settings?

Apologies for the spam, but for clarity I'm using an Archer C7 v2
router, with the MiniPCIe QCA9880-BR4A (v2) 3x3 a/n/ac PCIe radio
controlled by ath10k, trying to use 802.11ac with 5GHz. I can use the
5GHz band as an AP and get much higher speeds (in the 100's or more)
so I know the 22 Mbits/s is slower than the maximum, though I
certainly could be wrong on the channel widths point (it could be the
modulation scheme, maybe?).

Thanks again!
