Comment 31 for bug 575943

Joe

Here is the easiest instruction set I found to solve the broadcom issues as well as upgrading the kernel

If you have wireless cards Broadcom 43xx series first install packages

bcmwl-kernel-source 5.60.48.36+bdcom-0ubuntu5
bcmwl-modaliases 5.60.48.36+bdcom-0ubuntu5

located here for i386 https://launchpad.net/ubuntu/+source/bcmwl/5.60.48.36+bdcom-0ubuntu5/+build/1781446
and here for x64 https://launchpad.net/ubuntu/+source/bcmwl/5.60.48.36+bdcom-0ubuntu5/+build/1781445

Open the terminal and run the following commands

sudo add-apt-repository ppa:kernel-ppa/ppa && sudo apt-get update

sudo apt-get install linux-headers-2.6.35-17 linux-headers-2.6.35-17-generic linux-image-2.6.35-17-generic linux-maverick-source-2.6.35

Reboot and have the new kernel 2.6.35 installed
