Help! I installed Ubuntu 10.10 because I am an audiophile and the output to USB via livesession rhythmbox was noticeably better than Windows Vista using Foobar even with the Kernel streaming plugin enabled. But I cannot get the wifi adapter to work, and so I cannot really use Ubuntu.

The live session activated the Broadcom STA driver, but said it needed to restart to use it. I figured ok, let's install Ubuntu onto my hard drive and then the driver will work because a restart would accept config changes.

I installed it and now the "Additional Drivers" window comes up blank!

Help!

You need to activate the Broadcom STA driver. You will need a network connection other than the wireless. You should have seen a warning about haing a network connection during the install.

Okay, that's fine, it said that it was recommended . . . anyway, that is not an option for me.

How are you supposed to have an internet connection when no ethernet connections are available and your wifi driver isn't working?

Is there any other solution?

Look in the section labeled "sta -no internet access"

I have tried everything listed, exactly following the steps, step-by-step, and still get nothing.

My install will not recognize anything.

No STA driver, no nVidia drivers . . .

The Live Session CD (but not when booted via USB) would activate the wifi driver, but it claimed it needed to restart, which a live session can never do--if I understand correctly.

So far I can't do any of the things I wanted to do with Ubuntu. No Apple Lossless support, I can't play any mpeg or avi files, . . . and none of the drivers for anything work.

No, it is just saying that the drivers can be installed from the live CD, not to run from it. Bring it up normally and

" Systems installed from CDROM can simply add the install CD as a package source and install bcmwl-kernel-source, automatically installing the required dependencies. " Go to System>>administration>> software sources and put a check mark in "installable from CD Rom" and " and install bcmwl-kernel-source, automatically installing the required dependencies ".
