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.

For Dell 1397 wireless card, just search for 'bcmwl-kernel-source' in the Software Center and install it.

Please run the terminal command:

lspci -nn

Is your Broadcom wireless 14e4:4312? If so, please do:

sudo apt-get remove --purge bcmwl-kernel-source
sudo apt-get install linux-firmware-nonfree
sudo modprobe b43

If that is not your device, post it here and we'll assist.
