I have a problem with my wifi in Ubuntu (15.04). Recently, i have changed my wifi routers. Due to differents devices that was already configured, I have configured the new router with the same SSID and password, and this have worked for other devices but not for my Notebook with Ubuntu (in windows 7 in the same notebook it works!).
Intriguinly, If I change the SSID of my router network, it works in Ubuntu, but i don't want to change my SSID, because i have a lot of devices with this ssid/password stored.
Why i can connect to my network except when the ssid is the same of my old network?
Please, How can i fix my problem? Does someone know?
