    • [wifi] how to fix wrong regdom?

      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

                Channel 161 : 5.805 GHz
                Channel 165 : 5.825 GHz
      

      system information:

      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. 😞

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

    • RE: [wifi] how to fix wrong regdom?

      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?
