    Hello, I have a RPI 3 and I need to use the channel 12 to connet to the wifi router. I applied the following steps to have Access to this channel:

    sudo apt-get update
    sudo apt-get upgrade
    sudo apt-get dist-upgrade
    sudo rpi-update
    sudo branch=next rpi-update
    sudo iw reg set ES

    Two question:

    1.- I’ll have problems in the future doing this updates outside your „versión“?
    2.- On each reboot I need to configure the country code on the wifi (sudo iw reg set ES
    ), Can I do this change permanent?

    Maybe doing only the Country Code for the Wifi is enough for your current rasbian version.

    Thanks for your support

    Hi Bull,
    Could you please try using the web interface to connect to Wifi and then tell us the error message you would receive.

    Hello Heiner, thanks for your answer.

    That I could see, is that for default the wifi region, is configured in a country where those channels aren’t operative (maybe GB, I think so), so by default if you have your own wifi channel above 11 you cannot see the Wifi, so you can’t connect.

    After change the region to Spain in my case, doing „sudo iw reg set ES“, I can see my wifi, so the problem is that the region would by to default state after reboot and again I cannot see the wifi.

    My question is, How I can do this change in the wifi region permanent?.

    Many thanks

    PS. I’m a noob on raspbian 🙁

    Hi Bull,
    Please set the language and the time zone in the Settings/Reboot to your region. This should fix it.

    Hi Heiner,

    The language and time zone all ready changed to Spain, but not fixed the problem. so, It would be possible that the wifi region is independent of language region selected? I’m not sure of that.

    Hi Bull,
    The system should generally automatically detect and use the right channel. Please try using a freshly burnt image and connecting to the network normally via the web interface using the scan feature.
