please help or advise. i successfully installed ros 7.20 with wifi-qcom-ac package on a sxtsq5ac. i tried 7.18 too, but i get same problem - i can select ANY country, except superchannel. i get error “cannot set country”.
if i select any other country, it works OK and i get far better speeds (around 500-515 mbit on average) via wifi, but power is limited usually to 14dBm. which is too low.
is there a specific version of ros that has a working superchannel on qcom-ac package?
on a more recent device (ax), i can select superchannel but doesn’t do anything (not a problem for this topic- i gave up on ax).
It's even mentioned in wifi documentation ( but who reads that...)
In a controlled environment or if you have a special permission to use it in your region, you can select country=Superchannel (with this country profile, router's Tx output power will not be restricted by the software, and the router will output as much power as its hardware chip allows, unless manual tx-power is configured to lower it). Does not work for wifi-qcom-ac drivers.
