FAQ Section

Q1: What is a cable modem WiFi router combo, and why should I get one?

A: A cable modem WiFi router combo combines two essential networking devices into one unit: a cable modem (which connects to your ISP’s cable line and translates internet signals) and a WiFi router (which broadcasts the internet signal wirelessly and manages your home network). Getting one saves you money on monthly rental fees from your ISP and often provides better performance, more features, and a cleaner setup than separate devices or older, rented equipment.

Q2: What’s the difference between DOCSIS 3.0 and DOCSIS 3.1?

A: DOCSIS (Data Over Cable Service Interface Specification) is the international telecommunications standard for cable modems. DOCSIS 3.1 is the latest version, offering significantly faster download and upload speeds (often 10x faster than 3.0), better spectral efficiency, and lower latency. If you have a gigabit or multi-gigabit internet plan, DOCSIS 3.1 is essential.

Q3: What is WiFi 6 (802.11ax) and why is it important?

A: WiFi 6 is the latest generation of WiFi technology. It’s designed to handle more devices simultaneously, provide faster speeds, reduce latency, and improve battery life for connected devices, especially in crowded network environments. If you have many smart home devices, stream 4K content, or game online, WiFi 6 will offer a much smoother experience.

Q4: How much money can I really save by buying my own modem-router?

A: Most ISPs charge a monthly equipment rental fee, typically ranging from $10 to $14 per month. Over a year, this can add up to $120-$168. By purchasing your own modem-router combo, you can recoup the initial cost in about 1-2 years and then enjoy significant savings for the lifetime of the device.

Q5: How do I know if a modem-router combo is compatible with my internet service provider (ISP)?

A: Always check the modem’s specifications or the manufacturer’s website for a list of compatible ISPs and certified speed tiers. You can also visit your ISP’s website, as they usually have a list of approved customer-owned equipment. Compatibility can vary even within the same ISP depending on your specific plan.

Q6: What does “channel bonding” mean (e.g., 32×8)?

A: Channel bonding refers to the number of downstream and upstream channels a cable modem can use simultaneously. For example, “32×8” means the modem uses 32 downstream channels (for receiving data) and 8 upstream channels (for sending data). More channels generally mean higher speeds and better network efficiency, especially during peak usage times.

Q7: Do I need a modem-router combo with a multi-gig Ethernet port?

A: A multi-gig (e.g., 2.5 Gbps or higher) Ethernet port is beneficial if you have an internet plan faster than 1 Gigabit per second (Gbps) and want to utilize that full speed with a wired connection, or if you plan to connect a high-speed device like a powerful gaming PC or a Network Attached Storage (NAS) device directly to the modem-router. For most standard internet plans (under 1 Gbps), a 1-Gigabit Ethernet port is sufficient.
