Good to know
What is a premium modem?
A premium modem is a high-end cable modem that typically supports DOCSIS 3.1, offers faster Ethernet ports, and has better build quality and performance compared to budget models. They are designed for high-speed internet plans and demanding users.
Do I need a DOCSIS 3.1 modem?
If your internet plan is 1Gbps or faster, you should get a DOCSIS 3.1 modem. It is also a good investment for future-proofing, as ISPs are gradually shifting to DOCSIS 3.1. For slower plans, a DOCSIS 3.0 modem may suffice, but a 3.1 modem offers better performance.
Can I use any modem with my ISP?
No, you must use a modem that is approved by your ISP. Check your ISP’s website for a list of compatible modems. Using an unapproved modem may not work or could result in slower speeds.
What is the difference between a modem and a router?
A modem connects your home to the internet via your ISP, while a router distributes that internet connection to your devices, creating a local network. Some devices combine both functions, but many people prefer separate units for better performance and flexibility.
How do I set up a new modem?
Setting up a modem is usually straightforward: unplug your old modem, connect the new one to the cable outlet, plug in the power, and then connect it to your router or computer. You may need to activate it with your ISP by calling or using their app.
What does channel bonding mean?
Channel bonding allows a modem to use multiple downstream and upstream channels simultaneously. More channels mean higher potential speeds and better performance, especially during peak usage. DOCSIS 3.1 uses OFDM, which is even more efficient.
Is a modem with a 2.5G Ethernet port worth it?
If your internet plan exceeds 1Gbps, a 2.5G port is necessary to take full advantage. Even if your current plan is slower, a 2.5G port provides future-proofing. However, if your plan is 1Gbps or less, a Gigabit port is sufficient.
Can I use a modem with any router?
Yes, most modems have an Ethernet port that can connect to any router. Ensure your router has a Gigabit WAN port to avoid a bottleneck. Some modems with link aggregation require a router that supports it.
The bottom line
For most users, the NETGEAR Nighthawk CM2000 is the best premium modem because it offers the highest possible speeds with its 2.5G port and is built to last. If you are on a tighter budget but still want DOCSIS 3.1, the Motorola MB8600 is a solid choice. Ultimately, choose the CM2000 if you want the best performance and are willing to pay for it.
