Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I have recently installed ubuntu 12.04 LTS, but as in previous versions; I need a driver for wireless. When booting from USB, I could download and install the Broadcom Wireless STA driver: now I can't (note: this was from my house and I am moving and the internet in my hotel has additional logon information - might be the problem?). The ethernet cable on my laptop never worked, so that's not an option. When I open additional drivers, it will say can't detect drivers; need internet access.

Summary:

  • Need wireless driver
  • Wifi is available; logon information IN BROWSER required.
  • No ethernet

Not really.. This particular question should sound as how the hell can I install stuff if I have only a browser. –  Andrejs Cainikovs Jun 4 '12 at 17:09
    
I have long moved on from ubuntu, but to those it may concern, I solved this by getting internet on the Try Ubuntu option straight from the CD (because drivers work there). Then I installed and checked 3rd party firmware box, which gave me an install with internet. Thanks anyway. –  Ruben Jan 9 at 2:00

You can manually download any ubuntu package from http://packages.ubuntu.com, copy them to the linux drive, then use dpkg to install them. Packages.ubuntu.com also lists dependencies, so you should be able to find and download any that are missing.

The "restricted hardware drivers tool" uses the following package for broadcom wireless:

http://packages.ubuntu.com/maverick/bcmwl-kernel-source

(alter the URL to use lucid if needed for a 10.04 installation)

That package doesn't have much for dependencies, and it should be installable by doing:

sudo dpkg --install /path/to/bcmwl-kernel-source

dpkg won't try grabbing any dependencies for you, so you will need to make sure they are installed using this same method first.

This worked to install the driver - and it is the right one. Apparently it still doesn't show any networks in the NetworkManager applet. Any ideas? –  Lucas Jones Oct 21 '10 at 20:50

for broadcom wifi issues, follow the instructions here. this site provides step by step instructions for identifying the card and a list of supported cards and what drivers to use for each model.

make sure that you use this command to identify your card model, as the output of dmesg will sometimes contain the wrong information

lspci -vnn | grep 14e4

you'll probably end up using b43-fwcutter (should already be installed), so once you've downloaded the drivers linked to from that site, you can put them on a thumb drive, take the drive to your friends house and follow the instructions in the first link to install them.

to summarize:

on pc w/ net access:

wget http://downloads.openwrt.org/sources/broadcom-wl-4.150.10.5.tar.bz2

mv broadcom-wl-4.150.10.5.tar.bz2 /media/MyThumbDrive

then from the pc w/o net access:

tar xjf broadcom-wl-4.150.10.5.tar.bz2

cd broadcom-wl-4.150.10.5/driver

b43-fwcutter -w /lib/firmware/ wl_apsta_mimo.o

All Precise Pangolin (Ubuntu 12.04) packages can be downloaded from Launchpad.

You need to know the name of the package, though. But hopefully that should be the one:

bcmwl-kernel-source

Dependencies will need downloaded too (if any). –  Thomas W. Jun 4 '12 at 17:05
    
Correct, linux-headers. –  Andrejs Cainikovs Jun 4 '12 at 17:06
    
which i think is a meta package that links to three other packages... might want to dissect the debian/control file and see what it needs, and add those dependencies to your answer of "things to download" –  Thomas W. Jun 4 '12 at 17:08
    
Right. echo "linux-headers-"uname -r`"-generic"` should tell correct version of linux-headers package, that one might need to download. –  Andrejs Cainikovs Jun 4 '12 at 17:16
    
Thanks, I will surely try this out. And yes, while I was searching for an answer I stumbled accross bcmwl-kernal-source a lot. –  Ruben Jun 4 '12 at 17:20
