I have ubuntu 13.04.
In the software and update menu, under additional drivers, Were it says "Broadcom Corporation; BCM4312 802.11b/gLP.PHY" the box labbeled "do not use it ticked" and when i try tick the one that says "Using Broadcom 802.11 Linux STA Wireless drivers....." it wont let me apply changes, it starts doing it then stops and re-ticks the do not use box.
Because of this I can not use the wiress driver. Is there another way i can fix this. Or maby restore ubuntu to previous date.
I accidentally ticked the do not use box this morning and now can't undo it. I have restarted several times to try apply changes and still no luck
