I am running Lubuntu 14.04 b43.

Sorry I seem to have the same problem as many others. I have spent the last two or three days looking for other solutions and tried many of them to no avail. I get the error firmware missing on boot up but it doesn't stay long enough to copy it.

My wireless is BCM4312 LP-PHY 14e4:4315. I am running a completely fresh install of Lubuntu 14.04 on an old Dell Inspiron.

I have tried loads of things including:

Fwcutter and firmware installer eg, and I have tried to install it with this code:

sudo apt-get install linux-firmware-nonfree
sudo modprobe -r b43 && sudo modprobe b43

But I have had no luck. Please can you help?

Amazingly after trying this before several times, I have fixed it using

sudo apt-get update && apt-cache search b43

To find the firmware package. Then again:

sudo apt-get install firmware-b43-installer

No idea what I did differently this time

    The b43 firmware was removed from linux-firmware-nonfree back in late August/early September because of Broadcom licensing – Jeremy31 Jan 17 '15 at 15:26
