Gigabit Ethernet not working on Targus USB 3.0 Docking Station

zristic · 05-21-2013, 08:18 PM

I spent significant amount of time with Targus TACP70US to make it work properly. I would like to share my findings with others and to help solving the issue.

The first device I got did not work with video output, so I got it replaced.
The second one worked perfectly out of the box, but only for two weeks.

All of a sudden the video output did not work anymore so did not the ethernet connection. I contacted Targus support, but it seems I was emailing a bot since I got only generic replies saying I needed to update the drivers.

Of course, the driver update did not work and it took me some time to realize that windows/driver update always automatically updates the driver to the newest version, no matter what I install. That rang the bell and I started the procedure to revert drivers backwards until I got the device back to work. However, I had to turn off automatic driver update in control panel.

The DisplayLink driver that got the thing working is almost one year old- the version that works now with me is 6.3M1, from August 2012.

Ethernet is working now, so is the video output, but only at some resolutions. Earlier I had it working on most of the resolutions offered, but now I can normally use only two, which is not a bummer anyway.

I hope this findings of mine help others.

I also wish I could invoice Targus/DisplayLink for the hours I spent in fixing the issue. It took me quite a lot of time indeed, but let it be...

I spent a significant amount of time on this as well and was able to get it to work so thought I would share. In my case, the LAN driver wasn't recognized at all. I have an Asus Zenbook running Windows 8. Here's what ended up resolving it for me:

1. Downloaded and installed the latest DisplayLink drivers
2. Opened Device Manager
3. Found that Targus Giga Ethernet was shown as a Unrecognized Device
4. Chose to update the driver. Specify a driver and pointed to C:\Program Files\DisplayLink Core Software.

I found my audio driver was in the same state, but I haven't used that so it was not a big issue for me. The same steps fixed that also.

I had exactly the same issue. Ethernet driver wasn’t recognized, same for the audio.
I have an ASUS N56 notebook with Dynadock U3.0. I completed the 4 steps above. It worked for both the Ethernet and the audio driver

I am having the issue on a Surface Pro machine. Both Windows 8 and now Windows 8.1 (RTM) are showing the same signs. It shows as working "Limited Connection" (network glyph with a yellow exclamation on it). I see lights flickering on the back of the device but get no network. Attached is my diag output. Device manager shows all is good and that my drivers are up to date.
