Can tin foil block Wi-Fi signals like the radiation from wireless acces points?

Metals in general block electromagnetic radiation (which is what a Wi-Fi signal is). Aluminium foil is a metal, so ...Exactly how this happens is a bit more complicated than can reasonably be explained here, but it basically has to do with the fact that metals are conductive. They "absorb" the electromagnetic signal and turn it into electrical currents within the metal.
You don't even need to use solid metal, you can accomplish the same thing with a wire cage as long as the spacing between the wires is small compared to the wavelength of the radiation (for Wi-Fi at 2.4 GHz, this is about 5 inches). This is called a "Faraday cage." The basic concept is used in a lot of electronics devices to shield out interference (or keep the device from interfering with anything else), though it's more common for them to use a piece of thin sheet metal with maybe a few holes in it for ventilation than to go to the trouble of constructing a wire mesh.
