How Does Wi-Fi Work?

A wireless network uses radio waves, just like cell phones, television, and radios do. A computers wireless adapter translates data into a radio signal and transmits it using an antenna. A wireless router receives the signal and decodes it. The router sends the information to the internet using a physical, wired Ethernet connection. They transmit at frequencies of 2.4 GHZ or 5 GHZ. The higher the frequency allows the signal to carry more data. Usually for a laptop to get internet it ha to have a card to plug into the side of the laptop, the card comes with the wireless router usually. You plug your Armstrong cord into the router that Armstrong has given you. Then you take an Ethernet cord and plug it into that router and run it to the wireless router. If you have a desktop computer then you run an __Ethernet__ cable from the wireless router to the computer. Finally, you put the card that came with your wireless router into the side of your laptop and you will havLefte internet to it.
