A Range Extender is something you put halfway between your wireless access point and wireless trouble spot. Like on the first floor.
But that would only get you a stronger wireless signal down to the basement.

From there you would need a wireless bridge that would be in the basement and you could connect your devices to it wired.
You could look at something like sling link http://www.slingcommunity.com/page/shop but depending on how your house is wired it may or may not work.
Maybe buy it from a place you could return it to if it doesn't.
