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.
