I recently upgraded to Ubuntu 13.04 from the version before (12. something or other), and I found that since upgrading, I have not been able to connect to the Wifi network that I always connect to (my home network). It has the correct passcode, so that is not the problem, but it just cannot connect.
I have an HP Pavilion g6 laptop. If you need any more information to help this problem, I would greatly appreciate it. Thank you!
