How many is "many floors" up?
If the problem is distance or attenuation from solid surfaces (a basement probably has a pretty solid ceiling), and you can't cable between them or bring them closer together, the only options would be directional signal equipment or as KH mentioned a signal repeater.
The latter option is probably the best in most situations... if it's your ground floor/basement ceiling causing a signal loss you would probably have to install the repeater at the top of basement stairs.
