Hello Don,
Note that the Cisco* AnyConnect software is a VPN client, that would create an additional interface with the Operating System to connect to certain private networks.
Intel® Wireless Display (WiDi) would require for the notebook's connection with the Push 2 TV adapter to be on the same network, and the use of any VPN Client would interfere with this connection.
We have not seen this behavior, but it is better to contact Cisco* for compatibility on this inquiry.
Cheers!
