Motorola SurfBoard 6141 cable modem Speeds up to 343mbps 8X4 Bonded channels Works Perfect, I upgraded to a 16X4 due to having faster internet service This modem works with all the big carriers I used it for xfinity and it saved me over $100 per year in rental fees alone when you own your own modem you don’t need theirs and that gets rid of the modem rental fee in your bill which is like 13-15 dollars per month Hook it up call your provider to activate and your all set You also get your maximum speed with this modem versus theirs. I get 292+ mbps on this versus 100+ on the xfinity provided modem Great for streaming gaming and more This does not have a router built in You still need a wireless router Guaranteed to work perfectly.
