Stride ii: Speed Factor
Consider your internet speed. If your internet plan produces a 300 Mbps speed, an 8×4 channel modem (with a max theoretical speed of 343 Mbps or nigh 215 Mbps in actual speed) would not become you lot your full speed you are paying for with your ISP. Nonetheless, a 16×four aqueduct modem (max theoretical speed of 686 Mbps or about 372 Mbps in actual speed) would allow yous to accomplish your full speed.
Go on in mind, some net service providers will increase your speed for gratuitous for various reasons. DOCSIS iii.0 modems will somewhen become end-of-life, so it is strongly recommended to purchase a DOCSIS 3.1 modem. Some ISPs have already moved to exclusive use of DOCSIS three.i devices.
Even if your modem is capable of a faster speed than your current internet plan (e.g. a DOCSIS 3.1 modem), future-proofing benefits y'all in time. Read more than beneath nigh advertised modem speeds.
Step 3: Avoid Intel Puma Chipset Modems
Many cable modems include Intel Puma half dozen chipsets that have known issues with network latency and network jitter. You may read more about the problems on the Intel Puma vi chipset defects page, which too contains the total bad modems listing (the exercise non buy list). To bespeak a bad modem, ApprovedModemList.com will mark an Intel Puma chipset modem with a ♦ symbol.
Things You Should Know About Cable Modems
Why Purchase Your Own Cablevision Modem?
The first reason to purchase your own modem is to save money. ISPs may charge up to $15 a calendar month to rent one of their old modems. Therefore, y'all tin can relieve up to $180 a year on rental fees. Of course, those rental fees volition continue to increase every year likewise.
Subsequently five years, you could salvage upwardly to $900!
The second reason for buying your ain device allows yous to pick which features you lot want in your modem, every bit opposed to the Internet service provider forcing a express features modem on you. Therefore, you take control over the brand and specifications of the modem.
Inaccurate Advertised Speed Claims
Even though cable modem manufacturers state a certain speed on their modem packages, those speeds are usually unobtainable. For example, the NETGEAR CM400 modem states a speed on the package upward to 340 Mbps. All the same, ISPs will limit this speed for various reasons. Comcast states the CM400 will actually reach speeds up to 215 Mbps on their network.
The speed yous go will only be a certain per centum of the stated package specification. Why is that? Various factors like the blazon of server, total number of users on the network, computer equipment, services offered by the internet provider, and other factors will throttle the full output of your modem speed.
Keep in mind that the stated information charge per unit (download and upload speed) is merely a maximum theoretical number.
Fifty-fifty DOCSIS 3.1 modems may annunciate speeds of half-dozen or 10 Gbps, however the ISPs will limit these cable modems to 2.5 Gbps or slower due to network capabilities.
Cable Modem Channel Bonding
When you encounter a modem with sixteen×4 channel bonding, that means information technology has sixteen channels for downloading and 4 channels for uploading.
The dominion 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.
In other words, the more than data channels your modem has, the more than speed the ISP tin push to your home (if you have purchased the fastest speed tier from your Isp).
The nautical chart below explains the speeds for each aqueduct tier.
| Channels (DOCSIS 3.0) | Max Theoretical Speed |
|---|---|
| 4×4 | 172 Mbps |
| eight×4 | 343 Mbps |
| 16×iv | 686 Mbps |
| 24×eight | i Gbps or 1000 Mbps |
| 32×8 | ane.4 Gbps or 1400 Mbps |
| 2×2 OFDM/OFDMA (DOCSIS three.1) 32×8 (DOCSIS 3.0 mode) | 10 Gbps or 10,000 Mbps |
ISPs use the data channels of the modem to evangelize the internet to your home. The internet is like a highway and bottlenecks and slows during peak hours. Yet, having more lanes of traffic or information channels allows yous to avert congestion and keeps your total download speeds going.
DOCSIS iii.0 vs. DOCSIS 3.1
Information Over Cablevision Service Interface Specification (DOCSIS) allows for the transporting of data over a coaxial cablevision (net service).
The about widely used format by cable net providers remains DOCSIS 3.0. Nigh ISPs support DOCSIS 3.1, although some neighborhoods may have to wait years before DOCSIS 3.1 capability reaches them.
The primary difference between DOCSIS 3.0 and three.1 is the capable speeds. Comcast states that a DOCSIS three.0 32×eight channel modem will reach actual speeds of well-nigh 935 Mbps on their network. While a DOCSIS 3.1 modem will achieve a speed of thou Mbps or 1 Gbps or faster. If y'all want speeds in excess of 1 Gbps (for future-proofing), you need a DOCSIS three.1 modem.
DOCSIS 3.1 features backwards compatibility with a DOCSIS three.0 network. So, if your ISP has not yet upgraded to DOCSIS three.1, a DOCSIS iii.one modem will still function on a DOCSIS 3.0 network.
Pros and Cons of Philharmonic Modem and Router Devices
Many network devices classify as combo units. In other words, a cable modem and a WiFi router combined into 1 device. The list below contains the pros and cons of these devices.
Pros:

- Less hassle to set up since at that place is but one device
Cons:
- If either the router or modem fails or becomes obsolete, you lot have to replace the entire device
- Locked into the capabilities of a most likely limited WiFi router, as opposed to buying a split up, better WiFi router with more advanced features
Consequently, it is usually cheaper and easier to upgrade modems and routers separately.
Cable Modems vs. DSL Modems
DSL engineering science is older and slower. Most DSL providers are not in a hurry to upgrade their telephone lines. If you accept a selection of cyberspace service providers, choose a cable internet company. A few cable modems are capable of reaching speeds beyond g Mbps (or i Gbps). DSL cannot compete with the ultra fast speeds of cable internet (or fiber internet).
Cable Modem Care

To summarize:
- Internet service provider Compatibility
- Speed Factors
- Avert Intel Puma Chipset Modems
