The Wi-Fi router for your business works similar to a personal router you might have for a home network. The device connects the computer, or computers, to a network without the need for cables. Computers that have wireless access are able to connect to these routers and still access the web, or the intranet. With this type of router, it is possible for multiple computers to connect to the same network simultaneously. Keep in mind that there is generally a distance limit as to how far away these devices will work. It is generally around 100 feet.
