Where can I download network drivers for my BCM 4313?

Question

I'm running 10.04 Desktop Edition on my netbook, but it hasn't automatically installed my network drivers for my Broadcom device. I'd like to find a package on the internet for it, so I can transfer it to my netbook with a USB pen drive. I don't care if the drivers are proprietary. Here is the output of lspci.

See Wifi Docs Driver BCM 43xx from the Community Wiki. Looks like your card requires the STA driver. If you have Internet access, make sure the restricted repository (multiverse) is enabled, that repositories are updated

sudo apt-get update

then install bcmwl-kernel-source

sudo apt-get install bcmwl-kernel-source

Now you should see the driver available in the Additional Drivers (it's in System Settings). Install it. Reboot or run the following commands:

sudo modprobe -r b43 ssb wl

sudo modprobe wl

If you don't have Internet access, you can install bcmwl-kernel-source either by adding the Live CD as a repository or by finding the package on the Ubuntu install media (CD or pendrive) under ../pool/restricted/b/bcmwl. You'll also need the dependencies, those are dkms, patch and fakeroot. You can find them in ../pool/main/d/dkms, ../pool/main/p/patch, ../pool/main/f/fakeroot respectively. Install those before you install bcmwl-kernel-source.
