I recently bought a new computer that has an Atheros AR9485 wireless NIC. So far it has been working ok except this one issue: Randomly (as far as I can tell) it will completely lose the internet connection. The indicator in the top panel will still say we are connected but the machine has no internet connectivity whatsoever.
I've been able to get it working again by simply disconnecting from my wireless AP and then reconnecting, but this is annoying. Is there anything I can do to make the connection more stable?
I have tried passing the
nohwcrypt=1 to the driver, but that made it impossible to connect to any AP, it just infinity attempted to connect.
sudo modprobe -rfv ath9k sudo modprobe -v ath9k nohwcrypt=1
I've also tried upgrading my kernel to Linux 4.0 but the problem persists.

I'm running Ubuntu 15.04 on Linux 4.0.0-040000-generic on a Lenovo G510.
I'm wondering now if I could possibly have anything to do with my wireless mouse, which also operates on 2.4GHz..
