Gigabit Ethernet not working on Targus USB 3.0 Docking Station

[Wim]

The Ethernet on the dock must be set to auto negotiate, as there is no way to fix the port speed through the UI.

Also, half duplex modes are not supported, so if you try and force half duplex, the throughput will be very slow (due to packet collisions) and the speed will probably not be correctly negotiated.

Interesting, you mind explaining how to set this on the Targus Giga Ethernet Properties? I can only set a MAC address, VLAN ID, and Wake on LAN.

I have multiple other machines on the same network with Gigabit capability and have no issues with them on my Cat5/100Mbit network.

Where is the 'auto negotiate' setting on the dock or are you saying it is something the manufacturer (Targus) would have to set?

I'm just trying to understand. I appreciate the info and as I noted, just connecting the dock to a gigabit desktop switch that is connected to my network is working reliably now. Never had a gigabit capable device have problems before on my network. I am only posting as it was a pain for me and hopefully it helps someone. Thank you!

This thing is absolute trash. Do not buy it. I spent half a day wrestling with this thing trying to get it installed. I called both Targus and Dell support (I was trying to use it with a new xps laptop) and it simply does not work. Windows only recognizes it as a USB hub... the network, display, and audio do not work. Save yourself the trouble and look for alternate solutions. This is not only a waste of money but worse a waste of time and source of frustration.

This is only useful as an overpriced USB hub or brick.

Not to beat a dead horse here, but I have the exact issues with this same Targus ACP70USZ docking station. The Ethernet never worked right (would never negotiate to Gig speed), and I may have been able to deal with that, but the mouse lagging was the biggest thing I could not deal with. Just moving the mouse across the screen would pause (for up to a second or more) then jump to where it was supposed to be. I have read many others having this issue. This dock was almost $200 (from DELL) and is attached to an XPS12 Ultrabook (Windows 8) Tablet/Notebook convertible. I have the latest DisplayLink Software (version 7.2M0), but nothing I tried made a difference. I have replaced it with a USB 3.0 HUB from Plugable (7-Port) and connected my external monitor with the MiniDP connection on the side of the XPS12. Everything works smoothly (mouse too). The Targus dock is apparently at fault here.
