DOCSIS 3.0 Cable Modems
DOCSIS 3.0

DOCSIS 3.0 cable modems are some of the most widely used modems today, with 3.1 gaining the lead. Mostly because consumers today subscribe to 300 Mbps speed tiers or lower. As the need for higher Internet tiers goes up based on more streaming and smarter homes, DOCSIS 3.1 will become the norm. View the list of DOCSIS 3.0 cable modems below.


8×4 Cable Modems

8×4 Cable Modems

These cable modems have 8×4 channel bonding, No WiFi, or No Voice capabilities. These are only typically used for tiers up to 100 Mbps. However,  some ISPs allow them for higher tiers. These cable modems will soon be phased-out.  The TP-Link TC-7610 and Zoom 5345 belong in this group as well, however, they do not appear to be available anymore.


16×4 Cable Modems

These particular models feature 16 x 4 channel bonding which makes them ideal for speeds up to 300 Mbps. Easily compare these models here. All of these modems, with 16 x 4 channel bonding, are perfect for the following cable provider speed tiers…

  • Atlantic Broadband – Premier 250
  • Comcast XFINITY – Blast 200 & Extreme 300 Modem

24×8 Cable Modems

docsis 3.0 24x8 modems

24×8 cable modems are good for speeds up to 600 Mbps.  A couple of ISPs may approve it for faster tiers, but 600 should be top. Anything higher than that and you should use a 32×8 or DOCSIS 3.1 cable modem.  The TP-Link TC-7650 and Netgear C7500 both belong in the 24×8 category. However, they don’t appear to be for sale anymore.


32×8 Cable Modems

32×8 cable modems are good for speeds up to 900 Mbps.  They should not be purchased for Gigabit services, like XFINITY Gig, unless it is also DOCSIS 3.1 certified. We do not approve of any 3.0 modems with 32 x 8 channel bonding but have listed them for reference.  These were built with faulty chipsets that have caused a lot of latency and connection issues. This problem was an issue with all modem brands and not just one.  It was Intel’s fault. Since all the current DOCSIS 3.1 modems are backward compatible to 3.0 with 32 x 8 channel bonding, we recommend one of the modems in the following list over any 3.0 modems.
