Ethernet intermittently drops with dock. (Ubuntu 20.04.1 LTS, Targus DV1K-2K)

Hello everyone,

I’ve recently switched from a desktop setup, to a laptop/desktop setup. So I use a dock for connecting everything. The dock in particular is the universal Targus 2K (DV1K) which utilizes DisplayLink.

I have used this dock without really any major issues. However, every so often, I found the Ethernet connection associated with the dock just stops working. The internet just ceases, and it takes a few minutes for Ubuntu to notice. I have to unplug the USB 3.0 connector and plug it back in. Then all is good again. I’ve experienced it failing at random times it seems. A few times, back to back within 10 minutes of reinserting the dock’s USB. Other times, it can go for half of a day.

I was just curious if anyone was willing to help diagnose or solve this minor issue. If push comes to shove, I’ll use the laptop’s Ethernet for reliability. Maybe even as a fail over. But it sure would be nice to rely on the docks Ethernet. :pensive:

Thank you!

This looks like a technical support request.

No. It is foremost asking if anyone has “been there or done that.” But if it turns out no, than onto DisplayLink, which I’m sure will go over … productively.
