It turns out what was stated to be fixed
edit: … is fixed (at least for running 3 SSIDs on 5GHz mode and channel 36). Thanks alot to Turris team, you are fantastic!
There’s some small thing that drove me absolutely crazy (which is by no means the fault of the Turris guys - this is an OpenWrt problem): Even if you are parametrising a 5GHz-SSID you have still this options in luci configuration:
And if you uncheck the box for 802.11b legacy rates (equivalent uci option
option legacy_rates '0'
) the complete cards will not come up until you delete wifi-configuration and reboot your MOX. And this might also be the same if you choose “force 40MHz mode” (equivalent uci option
option noscan '1'
) - those options only belong to 2,4GHz networks and the mwifiex_sdio will crash if their default options are changed in luci.
What doesn’t work either is uci option
option require_mode '<n/ac>' (at least for 5GHz band) which is quite nice to force older devices to fall back on 2,4GHz band and leave 5GHz band to the newer devices.
