Thank you for asking. Normally if you have a cell provider that offers tethering as part of your cell service you should be able to just plug in your cell phone, enable tethering on the phone and away you go. However, my new cell provider does not support tethering but offers a lot of data as part of their service. Normally you would tether a computer to a cell phone and you have to install an app on the computer and an app on the phone and the two apps communicate between each other to form that link. Since the router is not a computer I have to find a way to install some code on the router’s USB port that makes it look like a computer to the phone. Using EasyTether on the router and the phone enables one to use the cell phone as is if it is normally tethered like a phone to a computer. Using EasyTether you still set it up the software on the phone which then “talks to” the software on the router. I hope that helps…
