Ubuntu – Ubuntu not connecting to wireless after restarting networking service


There was a problem with my internet connection and I thought that restarting the networking service might fix the problem. So I used sudo service networking restart command. However, my window manager crashed and I had to restart laptop to get it back. The problem is, ever since after that I haven't been able to connect to my WiFi. Anybody knows a solution to this?

Edit: I can see the wireless networks. When I connect to mine, Ubuntu keeps asking me for password even though I enter the right password.

Best Answer

If the wireless keeps on asking you for the password, do this:

  1. Click on the wireless icon on the top right.
  2. Go to Edit Connections...
  3. Highlight and delete the wireless network you are trying to connect to.
  4. Try to connect again.
