WI have a new Lenovo X240 that worked well with WiDi and a P2TV right out of the box. But once I installed our company's VPN client, it removed the ability of WiDi to work. There no longer was the ability to connect to a Wireless Display no matter what I tried to do and it seemed as it if made the system not compatible with WiDi.
Once I uninstall the VPN, WiDi is back working again.
I compared the Network Adaptor's device drivers before and after the install and saw that a number of new ones were added:
When I disabled the first new one, Intel Dual Band Wireless AC 7260 - Deterministic Network Enhancer Miniport, the WiDi came back to life.
But then I realized that WiFi no longer worked even if it showed connected - something about an IP Stack.
I am hoping that someone might know how I can keep WiFi (and VPN) working while also allowing WiDi to continue working.
Thanks!
