Hi im gonna be bitcoin mining but i already have a modem and im thinking of getting a modem and router in one box like the motorola surboard and im wondering if i can plug in my coaxial cable in my dish dvr slot with a coaxial splitter so will it make it like on signal or do i have to do it to the coaxial cable outlet the one that the modem is already using. with a splitter will it work because i dont want to get something that wont work thanks.
