Windows 10: Miracast and dhcp

using Miracast to project from a laptop to a projector and it does work but there are problems -

originally the laptop used dhcp (ip v4) on the network, and whilst mirror screens was on it could browse the internet. However once you stop mirroring the desktop and disconnect from the projector the problems begin. It seems as though the laptop decides to use the tunnel created for the desktop projection as main dhcp even when you've gone through the disconnect procedure. Ipconfig release and ipconfig flushdns do nothing. stopping and starting the dns and dhcp services dont help. It obstinately sticks to using a 169.254.*.* address and both wifi and networking refuse to connect. The only thing you can do is manually assign an ip address!

Anyone else had this and found a solution?

Mirror performance is weak by Windows 10 miracast.

I bought a miracast device, but I found a question that mirror performances are different when I respectively use two kinds of notebook with windows10 system to operate miracast. The more high configure notebook can upgrade to window10 (WDDM2.0), when
I use this notebook to miracast big screen by miracast device, break off after first miracast operation finish, go to miracast operation again, miracast operation is unavailable. But more low configure notebook upgrade to window10 (WDDM1.3) has never found
this kind of question, its miracast performance is good. So I wanna know why is this? what is window10 (WDDM2.0) miracast requirement?Thanks a lot!
