PLEASE HELP!!!!!!!!! If you have a modem with a built in router, you can use it as a wireless (wifi) router. Wifi doesn't cost money as a service. You just need the devices that are compatible with it. Wifi is just a different way of connecting stuff to the internet.
Some important points to consider when shopping for a Wi-Fi router are: the number of wired and wireless devices on your network, the types of online activities performed, and any issues that may be impacting your online experience, like slow downloads, data buffering, and lag.
