I have the UD-3900 (Rev B2) docking station, which is plugged into a USB 3.0 port on my Lenovo T450s laptop. When I plug my ethernet cable directly into my laptop, I get download speeds of around 500 mbs. However, when I plug my ethernet cable into my Plugable docking station, the download speed maxes out at 200 mbs.
I thought the docking station supported Gigabit Ethernet and that the speed wouldn’t be slowed down by connecting the docking station to the USB 3.0 port on my laptop? Do I have an older version (Rev B2) that didn’t have Gigabit Ethernet? Any other possible solution?
