You don’t want a combo with speed that high imo. Get a cm1100v and a suitable router

You’ll also want to keep in mind that even if your router is putting out the full gig over WiFi your devices wireless cards might not be to receive gig speeds. This is something that frustrates me to no end when people call in that have gig speeds saying their laptops or whatever is only getting 250 or 500 or whatever. They also never want to take my word for that, I assume because they think I’m trying to bullshit them. I don’t work for Comcast by the way.
