Buying Guide for the Best Router Modem Combos

Choosing the right router-modem combo can significantly impact your internet experience. A router-modem combo combines the functions of a modem and a router into a single device, simplifying your setup and reducing the number of devices you need. When selecting a router-modem combo, it's important to consider several key specifications to ensure it meets your needs and provides reliable, fast internet connectivity.
Internet Speed CompatibilityThis spec indicates the maximum internet speed the device can handle. It's important because it ensures that your router-modem combo can support the speed provided by your internet service provider (ISP). If your ISP offers speeds up to 300 Mbps, for example, you'll want a device that can handle at least that speed. Generally, devices are segmented into categories like up to 100 Mbps, 300 Mbps, 600 Mbps, and 1 Gbps or higher. Choose a device that matches or exceeds your ISP's speed to avoid bottlenecks.
Wi-Fi StandardsWi-Fi standards (such as 802.11n, 802.11ac, and 802.11ax) determine the speed and range of your wireless network. Newer standards like 802.11ac and 802.11ax (Wi-Fi 6) offer faster speeds and better performance in crowded environments. If you have many devices or need high-speed internet for activities like streaming or gaming, opt for a device with the latest standard. For basic browsing and fewer devices, older standards like 802.11n may suffice.
Number of Ethernet PortsEthernet ports allow you to connect wired devices directly to your router-modem combo for a more stable and faster connection. This is important for devices like desktop computers, gaming consoles, or smart TVs. Typically, devices come with 2 to 4 Ethernet ports. If you have multiple wired devices, choose a combo with more ports to accommodate them.
Dual-Band vs. Tri-BandDual-band devices operate on two frequency bands (2.4 GHz and 5 GHz), while tri-band devices add an additional 5 GHz band. This is important for managing network traffic and reducing interference. Dual-band is sufficient for most households, providing a good balance between range and speed. Tri-band is beneficial for larger homes or environments with many devices, as it can handle more simultaneous connections without slowing down.
DOCSIS StandardDOCSIS (Data Over Cable Service Interface Specification) is a standard for transmitting data over cable TV systems. The latest version, DOCSIS 3.1, offers faster speeds and better performance than older versions like DOCSIS 3.0. If you have a high-speed internet plan or want to future-proof your setup, choose a DOCSIS 3.1 device. For lower-speed plans, DOCSIS 3.0 may be sufficient.
Range and CoverageThe range and coverage of a router-modem combo determine how far the Wi-Fi signal can reach within your home. This is important for ensuring that all areas of your home have a strong and reliable connection. Devices with more powerful antennas or mesh networking capabilities can provide better coverage. Consider the size of your home and the placement of the device when choosing a model. For larger homes, look for devices with extended range features or the ability to add mesh extenders.
Security FeaturesSecurity features protect your network from unauthorized access and cyber threats. Look for devices that offer WPA3 encryption, built-in firewalls, and automatic firmware updates. These features are important for keeping your personal information and devices safe. If you have children, parental controls can also be a useful feature to manage their internet usage.
