Did you set up Wifi in Network Connections?

[JeremyB]

You likely need to install firmware-b43-installer and reboot

I had the same issue. This was the fix I found:

Go to the text file at: etc/NetworkManager/NetworkManager.conf (make sure you open this text file as root)

or alternatively enter this into your terminal:

Code: Select all

sudo nano /etc/NetworkManager/NetworkManager.conf

(I found it easier to simply navigate to the text file rather than use the nano program in the terminal)

add the line:

Code: Select all

[device]
wifi.scan-rand-mac-address=no 

Save and exit

then restart network:

Code: Select all

sudo systemctl restart NetworkManager

(enter this command in the terminal)

Had the same problem using two different USB wifi sticks and this worked for me, thank you!
