Gigabit Ethernet Port Not Working

[moobags]

Hello I have been having issues with the ethernet port working on my Targus USB 3.0 docking station (Model No.: ACP71AU). I plug it in, the connection lights on the port flash, it seems to be connected in network connections but I cannot get to web pages 99% of the time. Sometimes they will half load, but most of the time they will not load at all.

More details:

- Pings work fine (URLs and IPs)
- Same cable in other PCs (not using Targus Dock) works fine.
- Other cables (using dock) do not work
- WiFi works fine.
- DisplayLink software installed correctly
- DisplayLink service running
- USB device appears in device manager
- USB device booted correctly
- Latest graphics driver installed
- Latest USB 3.0 host controller driver installed

System details:

- Dell XPS13 L322X
- Windoze 7 Professional SP1 64 bit

Per other threads in this forum I tried uninstalling the displaylink software, updating windows, restarting and reinstalling the latest version of the displaylink software, but it did not fix the issue. I have attached the output from the Support Tool.

Any help would be much appreciated!

Hi,

Can you upgrade your USB 3.0 host controller driver to this one:

Done. Same problem.

If it works on your home network and not on websites, then it could be the MTU settings. This article could help:

I'm starting to think the NIC in the Targus docking stations are faulty. If I ping a server through the Targus Giga Ethernet, packets are randomly dropped. If I ping through another USB adapter, no packets are dropped. All the drivers and software are up-to-date, so that leaves the hardware as the likely problem. So sad. Never buying one of these again. DisplayLink should distance itself from Targus until they fix this.
