Wireless Driver problem(Acer)

Wireless driver didn't work when I installed ubuntu. This solved the problem. YOU NEED A WIRED ETHANET CONNECTION

  • Open the terminal
  1. type: lspci -nn | grep 0280 (This outines the problem)

  • The error should read: 03:00.0 Network controller [0280]: Broadcom Corporation BCM43227 802.11b/g/n [14e4:435}

  1. type: sudo apt-get install --reinstall bcmwl-kernel-source

  • After this type:
  1. type: sudo modprobe wl

  • If there is no error when the above is typed, the problem should be solved

Log in loop

Ubuntu got stuck in a log in loop. This solved the problem.

  1. Ctrl + Alt + F3 at the login screen will open the terminal.
  2. Type: chown username:username .Xauthority (username is the username of the login)
If this doesn't work there are more solutions here: http://askubuntu.com/questions/223501/ubuntu-gets-stuck-in-a-login-loop
