A:Answer The Wi-fi itself doesn't cost anything, if you have an internet service provider with a modem, then you would have to purchase a separate Wireless Wi-fi Router providing you decline to use the Router your provider provides for a monthly cost, if you purchase your own Router then, you won't have to pay a monthly fee, and therefore the Wi-fi is free, free to connect other devices that are Wi-fi capable and transfer videos or watch internet channels on your devices,, It's worth purchasing your own router,,
