Ubuntu 15.10 wifi connection but often fails to get inteet access

I am running ubuntu 15.10 and my Lenovo yoga 2 pro laptop often fails to connect to the Inteet. This happens randomly and could pass several hours before it is able to connect again. The laptop stays connected to the router via WiFi, but no Inteet access. Other laptops and smartphones connect with no problems to the net.

This is the output of ifconfig

Thanks for the help.
