Installing a AC1200 router - replacing a Comcast X1 router - problem: instructions state to connect router via ethernet cable to "modem" - there is no modem, just a cable incoming from Comcast service. The connections are coax cable (screw couplings) yet none exist on the router. Is there a screw end cable with an ethernet connection on other end for the router available? Thank you.
Re: Installation issue
Wrong forum - this is for the Arlo cameras.
Apparently you need to either procure a modem, either from Comcast or buy one, or return the router for a modem/router.
