Well that's slightly more of a challenge. But regardless Wifi is known to degrade rapidly over distance if walls are in the way, though everyone's mileage will vary depending on local conditions. One wall or floor is easy, even a router missing its antennae can deliver through that. However I find that two walls (and a requisite room in between) is pretty much the limit of reasonable usability in most deployments. Once you get to three typical walls and two rooms you're looking at slow/intermittent signal at best. But again that all varies according to equipment and local conditions. Annoyingly I find my mobile phone maintains the same performance at twice the distance compared to my flatmate's phones and laptops.
