My brother borrowed my laptop and inexplicably put a softblock on the wifi that I can't seem to undo. He would have only used the graphical interface and I think he said he did something like click 'disable wifi' which then caused the entire wifi icon to disappear.
I discovered the softblock like so:
Code: Select all
jugular@MintBook:~$ rfkill list all
0: phy0: Wireless LAN
Soft blocked: yes
Hard blocked: no
1: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
Code: Select all
jugular@MintBook:~$ sudo rfkill unblock all
Code: Select all
jugular@MintBook:~$ rfkill list all
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
1: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
Code: Select all
rfkill list all
Please assume I know nothing, I'm a casual Linux user and not a habitual user of terminal.
Thank you!
