मुझे इस समस्या के एक हिस्से के रूप में यह त्रुटि मिल रही है लेकिन चूंकि यह समस्या पूरी तरह से अलग मुद्दा है इसलिए मुझे लगता है कि इस मुद्दे पर अलग से विचार करना बेहतर है। मेरा wlan0 नीचे है। जब मैं इसे चालू करने की कोशिश करता हूं
$ sudo ifconfig wlan0 up
SIOCSIFFLAGS: Operation not possible due to RF-kill
और फिर
$ sudo rfkill list all
0: phy0: Wireless LAN
Soft blocked: yes
Hard blocked: no

त्रुटि संदेश का क्या अर्थ है? RF-मार क्या है?
