मुझे चैनल 12 का उपयोग करके वाई-फाई नेटवर्क से कनेक्ट करने के लिए मेरे आरपीआई 3 की आवश्यकता है, लेकिन मैं इस चैनल का उपयोग करने के लिए अंतर्निहित वाई-फाई एडाप्टर प्राप्त करने में सक्षम नहीं हूं।
यही मैंने किया है:
$ 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
जैसा कि आप देख सकते हैं सूची में चैनल 12 (या 13) शामिल नहीं है। क्या अंतर्निहित एडाप्टर के लिए चैनल 12 को सक्षम करने का एक तरीका है?
अपडेट: यह वही है जो मुझे dmesg में मिलता है:
