Wireless Comcast Xfinity Modem and Router combined
I have a Comcast wireless modem with router inside, and ever since they put me on wireless, my service to the lower level of my house has been horrible (the modem/router is in the far room upstairs). Can I connect this when there's already a router inside of the wireless modem that I'm using? Would it be better to insist that they put me back on a wired modem and then use this router with that?
