Query: Bad router

I bought this router in the hope of using the internet on my laptop antwhere in my two storied house. I use a linksys wireless card in the laptop.It turns out that as soon as the laptop leaves the room where the router is located and the door is closed, the receiving signal goes down to nothing.Tech support from Linksys by email said that this product only works in "line-of sight", while that is not mentioned on the package.For me a waste on money.
