DisplayLink Forum - View Single Post - Gigabit Ethernet not working on Targus USB 3.0 Docking Station

I wanted to share if it helps someone. This gigabit network issue has been a problem for me in my home office which is wired with Cat5 100MBt. I have 11 machines, many new ones with Gigabit adapters that have no problem negotiating down.

This Targus ACP71USZ dock's gigabit port simply will not reliably negotiate down or it seems even work on anything less than a 1GBit Cat5e or Cat6 connection.

What I did was take my source network (cat5/100mbt) and plug into a gigabit desktop switch. From that switch connected to the dock with a cat6 cable. Since then, network keeps working don't have to power off/on the dock or anything. It does not look like there are any settings for this Targus gigabit to have it work in 'slow mode' or half-duplex that I could find.

Hope this helps someone, besides this it has worked great for me and now I am OK with this workaround.
