Wireless Broadcom 4313 not working on Ubuntu 12.04
- by user88568
It seems a lot of people are having this problem, but none of the posted solutions have worked for me so far. My driver is installed and activated, I have tried removing and re-adding the network, and various other fixes. No networks were picked up on my first boot, the next day wireless worked fine, and since then it does not detect networks, and when I manually try to connect, it repeatedly asks for the password and does not connect. Here's my info:
