What does 16×4 modem mean?
For example, 8×4 modems—that is, modems with eight downstream channels and four upstream channels—support a theoretical maximum of 343Mbps. A 16×4 modem generally tops out at around 680Mbps for downloads.

How do I fix high upstream power level?
Disconnect your cable modem from the coax and power outlet then move it to the first coax jack. Reconnect the coax followed by the power. Test your signal levels again. If the upstream power is still too high at the first jack, there is nothing you can do on your end to resolve the problem.
How do I know if I need a new modem?
Three Signs You Need a New RouterSign 1: You had Internet access yesterday, but you can’t log on today. … Suggestions: This is a pretty good clue that your router has suffered a catastrophic failure. … Sign 2: You can’t seem to get anything done without your connection dropping off and reconnecting after a short delay.More items…•
Is 16×4 modem good?
A 16×4 cable modem is way more than you need unless you’re subscribing to your ISP’s fastest plans (300 Mbps or greater)—you’re more likely to see a speed boost going from 1×1 or 4×4 to 8×4; much less so going from 8×4 to 16×4. … An 8×4 cable modem is a perfect match.
Do modems go bad?
But, technology often changes faster than equipment stops working. There is a good chance that if you’ve had your modem for more than five years, you aren’t getting the speed you could be with a new modem. We recommend upgrading your modem every 3 to 5 years because of this.
What speed does Docsis 3.0 support?
170 Megabits per secondGet Familiar with DOCSIS (and Channel Bonding) The current spec available today, DOCSIS 3.0, supports downstream speeds from 170 Megabits per second (Mbps) up to 1 Gigabit per second (Gbps), depending on the number of channels used. Sometimes, you’ll also spot numbers like “4×4” and “8×4” when modem shopping.
How often should you replace cable modem?
every five yearsCable modems, based on how they work, are kind of a “wear item”, and generally do need to be changed out at a minimum every five years. (Those SB6141 8×4 DOCSIS 3.0 modems that everybody and their brother had, those are developing “bad caps” around now, so should be replaced anyways.)
Will a new modem increase my internet speed?
Buying a new modem can offer faster, more reliable Wi-Fi. It can also be the answer if you’re experiencing frequent drop-outs. But it probably won’t speed up your physical internet connection. Slow internet may be caused by other issues too, like the NBN speed tier you’re currently running.
What does 24×8 Docsis 3.0 mean?
24×8 DOCSIS 3.0 cable modem. 24 downstream channels for speeds up to 1,000 Mbps* 8 upstream channels for speeds up to 246 Mbps* * Actual downstream and upstream speeds depend on a number of factors including the speed of your cable service. Downloads 24 times faster than DOCSIS 2.0.
What do Docsis channels mean?
Data Over Cable Service Interface SpecificationData Over Cable Service Interface Specification, or DOCSIS, is an international telecommunications standard that allows for the addition of high-bandwidth data transfer to an existing coaxial cable TV system.
Is a Docsis 3.1 modem worth it?
The added expense of the DOCSIS 3.1 modems isn’t worth it until you’re on one of these new (and pricey) plans—especially since your ISP may roll out gigabit over fiber rather than cable. And they may not even let you bring your own modem once they do roll out gigabit service.
Does Channel bonding matter?
Channels are like lanes on a highway. The more cars on the road—the more traffic—the more congested the channels. … And that’s accomplished through a technology called channel bonding. Channel bonding combines multiple channels—or lanes—to increase the amount of traffic that a modem’s highway can comfortably support.
