I just installed Ubuntu but can't get online

Can you give the output of:

sudo lshw -C network; lsb_release -a; uname -a; sudo rfkill list

Thanks

Uhhh....what? English please?

It is English. The command is to be run in a terminal. Press ENTER after you paste it in (or type it 100% accurately). Give the output here as an update. You can run a terminal easily by pressing CTRL+ALT+T

Thanks I'll let you know if it works :D

I need help getting the driver for it.
b43legacy BCM4306
I also need help on the installation. Please and thanks XD

Yes the link shows how. There is a part talking about the firmware, which is what you need

Ok, I now have ANOTHER problem. My old computer that I installed Ubuntu on can't find this package "bcmwl-kernel-source", but that's the one that I need. Will I have to go through the computer that I initially downloaded Ubuntu on and find that file manually?

Add the install CD as a repo and install from that. It's on the link I gave.....

what do you mean by "repo"? because even the CMD commands aren't working sooo,...

In software centre enable the CD as a source. It will install ok then

I was using a Flash Drive in order to do this because I don't have any cd's to use. Would this make a difference?
Also, my old computer IS using Ubuntu as we speak, I just can't get the wireless networking adapter to turn on because of the missing files. I've also tried going through the CMD and entering "sudo apt-get install bcmwl-kernel-source" and it STILL says that the file cannot be found.

Thanks actionparsnip, that solved my question.

I think its already been answered by the experts. Also, my old computer IS using Ubuntu as we speak, I just can't get the wireless networking adapter to turn on because of the missing files.
