Issue: The wifi is not working on Ubuntu machine. The network options shows
'Wifi Disabled'
Solution:
1. Make sure your hardware wifi switch is enabled. Usually from keyboard you should be able to switch it on using Wifi symbol key (or with combination of function key and wifi key)
2. To verify if the wifi is blocked by hard or soft switches, you can by running th below command from terminal
Command:
user@machine:~$ rfkill list all
Output:
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
1: brcmwl-0: Wireless LAN
Soft blocked: no
Hard blocked: no
The output shows if soft or hard switches are blocking. If all of them shows no as shown above, that indicates that all look good. If not then see which one shows yes and use the below command.
Command:
user@machine:~$ sudo rfkill unblock all
Enter password and this will unblock the soft switch
If option 'hard blocked' in the output shows yes, that means the machine wifi hardware is disabled and you can enable it as described in point 1 above.
