The wl driver (bcmwl-kerner-source) for laptops with Broadcom wireless cards such as BCM4313 that can't use the open source drivers could not be installed or built on 12.10 Daily.
There's a bug reported on launchpad and a patch has already been released. I tried it and it works beautifully. Link to bug report and patch here: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/994255
