I was told by CableCo. (Xfinity) if I have my own router I would not have to pay for there's. I went out and purchased a Linksys ac1900 to use in place of cable's (xfinity) router to find out that the linksys does not have phone line ports to connect my land line in. I then went to Best buy to see if I could purchase a simple modem to plug my phone line in so I could, in turn, plug the modem into the Linksys but was told they didn't have anything that would work for that. Is there anything else I can do to correct this dilemma, short of sending my Linksys back and using cable's router/modem?
