        With a Nexus 5 otherwise running fine and with locale set to German, I cannot connect to wifi channels 12 and 13, that are legal channels in Germany. I've so far tried setting regdom via

        $ adb shell sudo iw reg set DE
        

        (no error message), but that doesn't seem to have any effect:

        $ adb shell iw reg get
        country 00: DFS-UNSET
        	(2402 - 2472 @ 40), (6, 20), (N/A)
        	(2457 - 2482 @ 20), (6, 20), (N/A), NO-IR
        	(2474 - 2494 @ 20), (6, 20), (N/A), NO-OFDM, NO-IR
        	(5170 - 5250 @ 40), (6, 20), (N/A), NO-IR
        	(5735 - 5835 @ 40), (6, 20), (N/A), NO-IR
        $ adb shell iwlist wlan0 channel
        wlan0     20 channels in total; available frequencies :
                  Channel 01 : 2.412 GHz
                  Channel 02 : 2.417 GHz
                  Channel 03 : 2.422 GHz
                  Channel 04 : 2.427 GHz
                  Channel 05 : 2.432 GHz
                  Channel 06 : 2.437 GHz
                  Channel 07 : 2.442 GHz
                  Channel 08 : 2.447 GHz
                  Channel 09 : 2.452 GHz
                  Channel 10 : 2.457 GHz
                  Channel 11 : 2.462 GHz
                  Channel 36 : 5.18 GHz
                  Channel 40 : 5.2 GHz
                  Channel 44 : 5.22 GHz
                  Channel 48 : 5.24 GHz
                  Channel 149 : 5.745 GHz
                  Channel 153 : 5.765 GHz
                  Channel 157 : 5.785 GHz
                  Channel 161 : 5.805 GHz
                  Channel 165 : 5.825 GHz
        

        system information:

        $ adb shell system-image-cli --info
        b'<elided>\n'

        version ubports: 20181126-12599
        version tag: OTA-6
        version keyring: archive-master
        version device: 20181126-2421
        

        firmware version (latest, I think):

        $ adb shell /usr/share/ofono/scripts/list-modems
        [ /ril_0 ]
            Revision = M8974A-2.0.50.2.30
        [...]
        

        I did observe the problem with OTA-5 already. Any suggestions how to activate wifi channels 12 and 13? The device feels one-eyed. 😞

          Can anybody confirm UT supporting local radio regulation? That is, regulatory domain is not set to 00 (worldwide) on a device? A shell command to check your device would be

          $ iw reg get
          

          The first line of output should contain a valid two-letter country code. Or is 00 what UT users get?

              @jezek Hmm … doesn't look too exciting. 😞 Can anybody share some information, if that is intentional behaviour?
