A. What you'll actually need is a wireless router. Netgear is the most preferred brand. They range in price depending on what size of wireless signal you need etc. (home, office...)Modems run internet connection from your DSL slot, and you usually need to plug an Ethernet cable into your computer to get connection. Routers on the other hand, are connected to your modem with an Ethernet cable, and transmit wireless signals throughout your home, office etc. You can also get security on routers, so other people cant connect to your home's connection without a password.

How do electrical signals get reconverted into sound energy?
Q. How does a telephone speaker work to convert the electrical signals from a telephone?

A. If there is enough energy (voltage) in the signal, it can be fed into a speaker where it goes through a coil of "magnet wire", made from an alloy which does a good job of generating a magnetic field. This coil is wrapped closely around a magnet; when the electrical energy is "flowing" in one direction, it will cause the coil to be magnetized with one end "north" an one end "south"; the fixed magnet then attracts or repels the coil with the effect of "like repels like", and visa versa. The paper cone attached to the coil will move to and fro to an extent equivalent to the power of the signal going through the coil, causing a sound to be produced. Without something attached to the coil to allow it to move air, no sound will be produced.… [cont.]

A. I am unfamiliar with anything called a can so if you're talking about a tin can thinking it can pick up internet signals you're crazy. What you need for wireless internet first is a wifi hotspot nearby or a neighbor with an unsecured wireless network or have your own Wireless network with a Wireless router. Second you need a wireless network adapter card you can either get a USB which will fit both a Desktop Computer and a Laptop computer like this one Or you can get a Card that is made for a desktop PCI like this one Or you can get a Card for a laptop PCMCIA like this one Good Luck HTH.
