I have the hardware as listed below. When connected to my Yoga 920c the ethernet keeps periodically losing connection approx every 5-10 minutes without a clear reason and then reconnecting, and I find that the ethernet connection is slower than the wifi. I have tried multiple ethernet cables without success. Can you advise?
