Hide Tether

I have a new AR750S that I have tethered to my One+8. I want to configure the router to hide the tethering?

If I connect the phone to a laptop via PdaNet/USB it’s not a problem. My friend says he can do it with a Total Wireless phone and a Wi-Fi Ranger.

Can this be done?

I think easytethering is built for this purpose.
