I have a relatively new Dell 4th generation laptop with Win 8.1. Latest updates including the Miracast update from Microsoft last week. Using a NetgearPTV3000, also relatively new.
Occasionally selecting "project" from the charms bar everything works as it should. Much more commonly though, the netgear WiDi device fails to connect. Usually if I delete the device from windows and then re-select that allows a connect. Sometimes I have to also cycle power to the Netgear device AND uninstall/reinstall the device in Windows. I have used the Intel update tool and I'm current on the WiDi software.
It's just a PITA to use so I sometimes end up just using a HDMI cable from my laptop to my TV. Kinda defeats the whole purpose of WiDi. When it connects it works great but that is the problem. Rarely does it connect without a long convoluted process.
Any ideas??
