Default Lost wireless connectivity on Windows 8.1

I have a Lenovo X1 carbon touch with Lenovo USB 3.0 basic Dock.

I upgraded from windows 8 to Windows 8.1

I cleaned up existing DisplayLink software using DL_install_cleaner.zip

Then I installed version 7.4 M2 version of software.

I lost wireless connectivity after doing this. Once I rollback using system restore, or remove all display link software, wireless is back to working state. Once I install 7.4 M2, I lose wireless connectivity again.

I have run System compatibility Check and it shows everything to be ok:
Pass: No Other USB graphics software installed
Pass: Basic mode support
Pass: Device attached
Pass: Device started correctly
Pass: Graphics driver date
Pass: WEI is above recommended 3

I have attached output from "Gather Support Information" and this information was captured after laptop has lost wireless connectivity.

The logs show that your Wireless is connected to a network:

I suspect this is due to USB 3.0 interference:

Question

Hello,

I have recently bought a DELL XPS 12 with D3000 docking station.
It worked properly (with 7.4M2 driver) until I upgrade to Windows 8.1.
Now, if I put the PC on the dock, I lose my wireless connection.
I need to move the PC of 20 centimeters in order to recover my wireless connection.
I have read the link above (intel) but if you have any ideas or a solution, please let me know

Many thanks

Xavier

Hi,

For information, if it can help you, I've recently upgraded the driver of my Intel WLAN Network card with the last version and the problem seems to have disappear
No interference between WLAN Card and USB 3.0 port of the dock station.
