Screen casting help topic

I have a China miracast adapter and it actually works great in dlna mode. When I try and connect in miracast mode. It constantly connects and disconnects. I've tried 20 or so different apps from play store and nothing. Now the kicker is my daughters cheap kocaso tablet with 4.4.2 connects with nothing more that the cast screen button n display settings. Anyone else have issues with this phone connecting? Or suggestions? I'm on xtrasmooth ROM currently fully updated. I have also flashed 5-6 others with no avail.

Thanks
