Unable to set wifi regulatory region

[electriccrowbar]

I'm not able to scan for or connect to several of my usual wifi networks (generally the higher numbers).

iw reg get showed I had an unset (00) region so I tried to set it and I don't seem to be able to. I'm using Manjaro pre-release 4 but have seen similar behavior on Debian.

I've tried a few different ways of setting my region but none have had worked.
- Setting region with iw reg set returns 0 but has no effect.
- Installing crda and setting my region via /etc/conf.d/wireless-regdom doesn't have an effect.
- Setting it manually in the module with echo "options cfg80211 ieee80211_regdom=US" | sudo tee /etc/modprobe.d/cfg80211.conf does at first appear to work when I check my region but I'm still not able to see any more channels.


I can work around this at home (at the cost of more congestion) by setting a lower channel, but when traveling i'm out of luck pretty often.

Could not connect my PBP on Manjaro to my 5Ghz network.  Set the control channel to 44 and the channel mhz to 40 and could connect to it.

Had no problem with the ubuntu and debian images, but just Manjaro.

iw reg get was giving me the same 00 as you previously (on Preview 4), but now I'm getting:

$ iw reg get
