A friend and I are thinking about splitting the cost on a router or access point to provide our entire dorm floor with wireless access (to all of those with laptops and wireless cards). However, seeing as how this is a dorm, it's a bunch of walls (not concrete, even though they're "painted" to look like concrete... not sure what it is) and such, so the signal may not reach the entire floor (or at least this half of it, the other wing of the floor is on it's own). Are there any routers or AP's with really powerful signals? Also, where would the ideal place be to set one of these up? It has to be in a room, so no matter what there would be a wall blocking it on all sides. Higher is better, correct? So setting it on top of a closet might help? Or maybe even duct taped to the ceiling?
