This question already has an answer here:
I'm trying to run Ubuntu 12.10 32-bit from a live USB, and it doesn't detect my dell 1397 wireless card. (I know there are many seemingly duplicates here but so far I haven't found any other case of this happening.)
I've followed these instructions Where to get Dell Inspiron 1545 drivers for the Dell 1397 wlan minicard wireless card?, ie executing
sudo apt-get update; sudo apt-get install bcmwl-kernel-source
and the card is inmediately detected. It is however impossible to subsequently boot the USB drive afterwards, as it throws a kernel panic booting up.
Which is the proper way to get the Dell 1397 driver working under Ubuntu 12.10 live USB with a persistance file size of 2GB? I can recreate the live cd, so there's no need for instructions on how to recover that installation. I do need however a definitive answer: there are way too many different responses on seemingly similar questions here.
