I have win 8.1 and ubuntu 14.04 installed on my lenovo ideapad yoga 2 13.
I'm getting a solid wifi connection on win 8.1 but not so much on
ubuntu. The connection on ubuntu works for the first few minutes before
dropping dead. I get the connection back only after rebooting or by
placing the system close to the router.

I have win 8.1 and ubuntu 14.04 installed on my lenovo ideapad yoga 2 13.
I'm getting a solid wifi connection on win 8.1 but not so much on
ubuntu. The connection on ubuntu works for the first few minutes
before dropping dead. I get the connection back only after rebooting
or by placing the system close to the router.
