No wireless with Mint 18 [SOLVED!]
« on: July 23, 2019, 09:13:21 am »
I have installed Mint 18 on a friend’s Dell Inspiron 1501 laptop.  Unfortunately, the built-in wifi doesn’t work with this installation although a USB wifi dongle works well (so I know that the network is set up correctly) as does Ethernet. 

Wifi enabled in BIOS and the network info entered. 
Keyboard Fn F2 to toggle wifi has no effect.
Here is some output that might help diagnosis:

harry@dell1501 ~ $ rfkill list all
harry@dell1501 ~ $ iwconfig
lo        no wireless extensions.
eth0      no wireless extensions.

----------------------------------------

I’ve installed  b43-fwcutter and firmware-b43-installer
I am guessing that the installer installs the b43-fwcutter but I don’t know how to use it.
I did find an example of the use of b43-fwcutter:    b43-fwcutter -w /lib/firmware wl_apsta.o
but I’m not confident about just copying this as it might not be appropriate for this machine. 
Can anyone advise me on the the best way forward?

Thank you

You don't need to be messing with b43-fwcutter

Just attach to the router with an ethernet cable (or other wireless card) and run:
Code: [Select]
sudo apt-get remove bcmwl-kernel-source broadcom-sta-common broadcom-sta-dkms
then
Code: [Select]
sudo apt-get install firmware-b43-installer
then REBOOT to test.
