I just installed Ubuntu and love it so much, its so fast now. But I have a problem connecting to the internet.

I checked and saw I have to install the driver Broadcom STA wireless driver but every time I do try to install it it says:

Sorry, installation of this driver failed. Please have a look at the log files for
details: /var/log/jockey.log

I went to the terminal and copy and pasted the log file name. and when I did it, it said I have no permission to access this file. I checked on the forums that I have to be on a wired connection. So I plugged my laptop into my router and I got internet then tried to install the driver again. And it was loading then when it got to the end the same message popped up.

Also I have one of those little USB router things you plug into the computer and it gives you internet I have been using that but its to slow. So I want to use the one in my computer but cant.

Also I tried the command:

sudo modprobe wl 

and when i type that command in it says:

FATAL: Module wl not found

Also I'm using Ubuntu 12.04
