Do you have a switch or shortcut to enable / disable WiFi? If so, press it

Jeremy (wa113y3s) said : #2

I think the hard block is caused by bcmwl being used on a chipset it is not ideal for, in terminal do

sudo apt-get install firmware-b43-installer
sudo apt-get remove bcmwl-kernel-source
sudo shutdown -r now

Can you help with this problem?
