Kanal 12'yi kullanarak bir Wi-Fi ağına bağlanmak için RPi 3'üme ihtiyacım var, ancak bu kanalı kullanmak için yerleşik Wi-Fi adaptörünü alamıyorum.
Ben de bunu yaptım:
$ sudo apt-get install wireless-regdb iw crda
$ sudo iw reg set NO
$ sudo iwlist wlan0 channel
wlan0 11 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
Gördüğünüz gibi listede kanal 12 (veya 13) bulunmuyor. Yerleşik adaptör için kanal 12'yi etkinleştirmenin bir yolu var mı?
