Comment 20 for bug 700176

For Lucid users there's fantastic news :)

Just download the natty package from

http://packages.ubuntu.com/natty/amd64/bcmwl-kernel-source/download

ok well thats for 64-bit.

anyway you just install that, and everything builds fine and once again you can use the wireless networks. I believe we get this trouble when we run newer kernels than those that are in lucid-updates.

I'd imagine the same solution would work for maverick users. and it also upgrades the existing bcmwl-kernel-source driver so you benefit from the latest fixes too!
