My lenovo x201 has a constant problem of disconnecting after a short period of time. I have reason to believe that this is because it switches to power off to save energy. How do I manage wifi driver in Ubuntu. I'm new to it but in windows I would fix this by, control panel -> system properties -> device manager -> under wireless card select property.

-untick windows device swithoff for power saving -Power output to maximum -Roaming aggressiveness to low.

What you are seeing, is probably the power management setting kicking in.

Try openening a terminal and running the command iwconfig wlan0. That will tell you if Power Management is turned on or off.

To permenantly turn off power management, follow the guide here.

Good luck.

ifconfig only shows ethernet-layer properties of an interface, maybe you meant iwconfig? – mniip Feb 25 '14 at 8:15
