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?
