Also when I type

there is nothing printed out.

[bhkkmp]

Any help would be appreciated ...

Your broadcom car needs a driver. If you are connected via Ethernet Then do the following in a terminal.

Code: Select all

sudo apt install bcmwl-kernel-source

reboot
Wireless should work.

[bhkkmp]

I ran the command and it installed but did mention something was FATAL

When I rebooted the wifi is still not workinig.

Rerunning the command does not give the FATAL message again because it says bcmwl-kernel-source is already the newest version so nothing to install.

What can I try next?

[kc1di]

Issue the

Code: Select all

 rfkill list

command again show any output.

[bhkkmp]

When I type in

rfkill list

there is nothing printed out

[kc1di]

Ok do this in a terminal and reboot see if it works?

Code: Select all

sudo apt install bcmwl-kernel-source

(note you'll have to be connected via Ethernet cable to work.)

Post results for

Code: Select all

mokutil --sb-state

[bhkkmp]

When I run sudo apt install bcmwl-kernel-source

The return says that the package is already installed

When I run mokutil --sb-state
The return says that there is no such command as mokutil

There is a modutil command however.

Sorry to thread-crash, but I was quite sure the second-hand laptop I'd bought recently had a broken wifi as I'd tried several times using the driver manager to get it up and running.

I just tried the above and it's working! thank you!
