But everything is cheap on the internet now. I just bought this WiFi range extender for $36 bucks on Amazon (you can see it plugged in on the upper left in the photo above) which just plugs in to a power socket and creates an extended network of your existing WiFi network with an "_EXT" after it. While I only get a couple of MB up and down (my unit is 30 MB both ways near the main router) this is fine for listening to tunes especially since it can buffer shows on Sirius XM (when it isn't live).
Don't suffer through dead zones. Buy a wireless range extender and then you don't have to curse your extended abode anymore.
