Yesterday I have made some updates and upgraded my linux 14.10 to linux 15.04.. Now I can't connect to my home wifi, and the others i get a dns_probe_finished_no_internet.. In the network-manager appears some really weak connections, but not my own which is 1 meter away and working because i can use my smartphone with it.

The Laptop is a Toshiba L650 and the wireless driver is a broadcom Corporation BCM4313..

Is this possible to repair? I have tried some things that appeared on google but nothing seems to work.
