Re: Broadcom STA Wireless drivers not working on Dell Inspirion 1501, Ubuntu 12.04
The driver b43 requires firmware which is proprietary so it's not included by default in the free and open source Ubuntu install. We install the nonfree firmware package; then we unload the driver and reload it so it sees and grabs the shiny new firmware.
The offline approach usually involves me attaching a zipped firmware file to my reply, and a USB stick so it can be transferred to the internet-less computer and installed in the correct spot so the b43 driver finds it as expected. As I said, I don't usually start there, but it's an available option if needed.
