My UD-3900 has been dropping Eithernet traffic whenever I use it. This causes intermittent lag and hang-ups in everything from simple web browsing to network applications, especially those that have to communicate back to a database.
In testing, continuous pings typically drop 2 pings to every 6 successful replies, and although that’s just an average (sometimes it drops more or less to more or less successful), it’s very typical that it will drop a couple to every several successful pings. This is very regular and consistent for whenever I’m using the Plugable Ethernet adapter.
I have confirmed that the connection through the network switch is stable as I can connect a different USB-to-Ethernet adapter and it works fine with no connection issues and 0 pings dropped. So the network itself is not the issue. Both the Plugable dock and the other USB-to-Ethernet adapter connect at 1Gbps.
I’ve updated the Plugable driver to the latest DisplayLink version: 8.5.3447.0 - This didn’t resolve the issue.
I’ve also unplugged all devices (monitors/USB/audio), leaving only the Ethernet cable connected, and it still drops communication. Rebooting the UD-3900 dock doesn’t resolve the issue either.
My laptop that the dock is connected to is running Windows 10 (build 1803).
I’m looking for support options to try to resolve the issue or an option for return/replacement if I can’t get it working properly. I purchased the Docking station on 4/19/2018 from Amazon.
