I spoke too soon about the DNS being the issue. When I had the Onelink+ dock ethernet enabled, I also still had the Wifi enabled, and this allowed the IP address to still go through the browser, but probably through the Wifi. Typing domain names however is failing to get through the dock ethernet. When i disable the wifi first, then enable the dock ethernet, no internet connectivity, regardless of direct typing of IP address or domain name.

I am also having this issue, Windows 7 Pro x64 on a brand new X1 Yoga with the OneLink+ dock.
I currently have version 7.23 of the Realtek driver installed which I downloaded directly from their web site.

A driver that resolves loss of ethernet function on X1 Carbon systems using a OneLink+ dock is currently under test and scheduled to be released by next week.
I will post again when it has been published.

This new driver 10.15 has made no difference to my 6 lenovo X1 Carbon G4's which use these Onelink docks. We still lose the network port when we undock and dock the laptops. Requires pulling network cable, display cables, and power cable and replugging in to fix. This is getting really frustrating!
Windows 8.1 64 bit.

We've installed the new driver on some X1 4th Gen Carbons and the problem still exists. If you unplug the power cable from the power adapter block and plug it back in, Ethernet is restored. It's strange because unplugging power from the dock nor the plug from a power strip doesn't do the trick.
