[Please help! My Media Center Can't find Extender (Xbox 360)]

I had the same problem. I figured it out.

Go to the network and sharing center>

Click on view status>

Bottom left click properties>

Click continue when windows asks for permission>

Click the sharing tab at the top>

make sure to UNcheck Allow other network users to connect through this computers internet connection.

That fixed mine hope it helps you. I spent 2 days changing things around on my laptop to no avail. unchecked that one box and it popped up saying extender found.

Yeah Im having trouble doing these steps. I got to network and sharing but I cant

find the view status> properties. Wondering If you can help Me out with that Matt?
