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. 
Thank you!
