RFKill

Somehow my linux laptop sometimes disables WIFI when I upgrade it. It doesnt really bother me as I can enable it by an icon in the UI but one day my UI lost the panel with that icon after another upgrade. So I had to learn how to enable the wifi. Via this page, I learned about the different status and then checking the options of rkfill command got my WIFI enabled back again.

# rfkill list
0: phy0: Wireless LAN
	Soft blocked: yes
	Hard blocked: no
1: hci0: Bluetooth
	Soft blocked: yes
	Hard blocked: no
# 
# rfkill unblock wifi
# 
# rfkill list
0: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no
1: hci0: Bluetooth
	Soft blocked: yes
	Hard blocked: no

At some point, I would like to test bluetooth in my laptop.
