Anyone looking for a comfortable and quick solution for a Gigabit Ethernet Adapter, which is recommended for this combination. That part worked with Windows 8.1 instantly and easily. The advantage is that you do not have to do without the USB 3.0 port. I had purchased the part, because I have no GBit-capable Ethernet adapter onboard. The speed is ok. I had reached 40 MB / s via FritzBox to NAS. The limiting factor here was certainly not the adapter but the NAS. As a USB hub, the adapter works just as fast as my other USB 3.0 hubs. For the price a strong buy recommendation.
