> I'm using Ubuntu 14.10 with Linux version 3.16.0-28-generic on Lenovo Yoga 13 using the built in rtl8723au driver from the kernel. At random times my internet doesn't work. I disactivate the internet and reactivate it to get it working again. It is usually at this time where most of the system hangs and freezes occur. The computer hangs and freezes occur at random times as well. I've used many wifi connections and types and they all cause the bug. The driver from lwfinger works flawlessly. Maybe there was some code regression? I've attached several log files.
