Please generate an overview of your system like this:
- Launch a terminal window (this is how to launch a terminal window);
- make the terminal window full screen, to avoid chopped lines;
- copy/paste this command into the terminal:

Code: Select all

inxi -Fxz
(if you type: the letter F is a capital letter)

Press Enter.

Copy/paste the output in your next message.

carl@carl-Inspiro ~ $ sudo rfkill list all
[sudo] password for carl:

Hard blocked: no
carl@carl-Inspiro ~ $


I was wondering. Should I have had the cat 5 cable unhooked when restarting?

OK, reverse the driver:

Code: Select all

sudo apt-get purge b43-fwcutter firmware-b43-installer && sudo apt-get install bcmwl-kernel-source
Then reboot.

Then repeat the rfkill command:

Code: Select all

sudo rfkill list all
.... and post the output.

No. Keeps coming up with Authorize, but I have checked and rechecked the line to connect and the pass is correct. Still no connection. Is there some way I can clean that up?

EDIT: That got it. I had two "S"'s together. One lower case and one upper case. I had them transposed.
Thank you very much! :D
