A real nervendes part. It's all very silly enough that my Yoga 2 has no Ethernet port, but this solution is real scrap because the cable connection - is not automatically detected - even with the latest drivers. Instead, I have to always reboot make - actually two reboots, since the first time the computer hangs. Only when the second restart, the cable connection is detected. Unfortunately, there is no other solution - except for a new computer or another workstation (with WLAN).
