How many downstream and upstream channels do I need?
Any new modem you buy should have at least 16 downstream channels; anything less is probably either old or underpowered.
What does 16×4 modem channels mean?
Originally, DOCSIS used one channel for downloading data and one channel for uploads. 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.
Do I need more modem channels?
When you see a modem with 16×4 channel bonding, that means it has 16 channels for downloading and 4 channels for uploading. The rule is simple – the more channels a modem has, the faster the data rates will be. So, a 16×4 channel modem achieves a faster data rate than an 8×4 channel modem.
Does Docsis 3.1 increase speed?
DOCSIS 3.1 provides faster Internet speeds using advanced signal processing techniques that increase the available spectrum for transferring downstream and upstream data. This process transmits more data traffic, faster and more efficiently.
What is a good upstream power level?
Downstream and upstream power levels are important when determining if the cable line that is connected to your cable modem or modem router is receiving sufficient power. Good Downstream power levels are within -7 to +7 dBmV. Good Upstream power levels are within 38-48 dBmV.
How many upstream channels should I have locked?
Upstream power level limits depend on the number of upstream channels locked. For some networks, the power limits for 3 to 4 channels are 35 to 51 dBmV. Ideal levels are approximately 40 to 50 dBmV for single channels, 37 to 48 dBmV each for 2 to 4 channels.
What are channels on modem?
Cable modem channels are displayed as “ downstream channels number x upstream channels number.” For example, 8×4, 24×8 or 32×8. The downstream is always listed first. The upstream is always listed second. For example, 8×4 means that your cable modem has four (4) download channels and eight (8) upload channels.
How do I lower upstream power level?
Locate the “Upstream” section and find the listed power level. Acceptable levels are usually between 30 dB and 55 dB. If the upstream power is above 55 dB, it needs to be lowered. Disconnect the modem’s power, wait five seconds and reconnect it.
How do you know if you need a new modem?
Signs that You Need to Replace Your Modem
- The modem won’t turn on.
- You can’t connect to the internet at all.
- Internet connection drops in and out randomly.
- Internet speed is inconsistent or is consistently slower than it used to be.
- You frequently need to reset the modem to get it functioning properly.
Is 16×4 modem enough?
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 you need both router and modem?
Do you Need a Modem or a Router? You will need both a modem and a router if you want to use WiFi or connect multiple devices. Since most modems only have one LAN Ethernet port, you can only connect one computer at a time, but it won’t provide the same security that a router does.
How fast should my modem be?
The average internet speed in the US is around 180 Mbps, and the fastest cable tier most major ISPs offer is between 100 and 1,000 Mbps (aka gigabit). If you have service ranging from 100 to 300 Mbps, a 16×4 modem will be enough. If your internet plan is over 300 Mbps, you need a 24×8 modem or better.
How many channels does my router need?
If you want maximum throughput and minimal interference, channels 1, 6, and 11 are your best choices. But depending on other wireless networks in your vicinity, one of those channels might be a better option than the others.
