Go on the map of the network and you will find your PC...not the extender but the pc you are using.
right click on it and click on manage
computer management comes up
click on Services and Applications
than on Services
a list comes up where you will find UPNP devise Host.
click on it and click on restart. Than everything took care of itself!!!
