Confirmed that arch hostapd package 2.10 from earlier this month still does not seem to have 802.11ax compile flag enabled. There’s an open bug about this from 2 years ago that package maintainers seem to have missed now that 2.10 is out. Trying to get their attention about it, but fly spray (arch Linux bugs site) refuses to send my sign up email. Yay.
Compiled hostapd from git repository from w1.fi , set compile flags, got 802.11ax working on 5ghz on the CF-953AX. But, I can only get 20Mhz width channels working so far, so my phy link rate is still ~130mbps or so. The folks on the morrownr/usb-wifi GitHub issues queue have been having some ideas though.
Need to try on the MT7921K and AX210 m.2 cards soon.
All the 6 GHz channels are marked no initiate radiation, so I’ll have to figure out what regulatory domain setting will unlock those for me…
