Lenovo USB 3.0 Dock ethernet driver problems with fix IP

[DispLnkUser]

Did you every get anywhere with this issue? I have had the same issue with Display Link and setting a fixed IP address. In my case I have a Dell M3800 which has no physical Ethernet port available. Everything is done through USB to Ethernet adapter or USB 3.0 Dell docking station. My work requires that I connect to many different devices by setting up a static IP address to do so. This capability is critical for me. I have the same issue with both the dock and two different USB to Ethernet converters. When I set a static IP address and then close the setup windows, when I go back in to check the address, it is gone. Early on I spent days trying to figure this out. I finally found that it was somehow related to the DisplayLink drivers. I am currently running windows 8.1. I found that when I loaded a certain DisplayLink driver version everything worked the way it was supposed to, but now I am stuck at this version. If I uninstall the DisplayLink Driver my problem comes back and if I try to upgrade to anything newer my problem comes back. It is a bad situation, because if I can't set a static IP I can't do my job. I haven't been able to figure out what to do. I have an image of my PC and if I make any change to the DisplayLink Driver the image is my only way to get things working again. If you figured anything out or have info that may help it would be greatly appreciated.
