Buying Guide: Key Purchase Considerations
- Compatibility with your internet service: Verify provider support (Xfinity, Spectrum, Cox, etc.) and any exclusions such as Verizon, AT&T, or bundled voice services. DOCSIS 3.1 models generally offer higher future-proofing than DOCSIS 3.0.
- Speed versus coverage: WiFi 6 (802.11ax) improves efficiency in busy networks and supports more devices. Consider router range (square footage) and number of concurrent devices when choosing a model with built-in modem vs. separate modem/router.
- Gigabit ports and USB: Check Ethernet port count and USB capabilities to support gaming consoles, NAS storage, and other wired devices. Port aggregation can boost throughput on wired setups.
- Future-proofing: DOCSIS 3.1 readiness and WiFi 6/6E compatibility offer better longevity as internet speeds rise. For homes planning upgrades, prioritize multi-gigabit capable devices.
- Network features: Look for features like VPN servers, beamforming, Range Boost, and Easy Mesh compatibility for expanding your network easily.
- Cost of ownership: While renting from providers is convenient, purchasing a combo unit can save rental fees over time. Compare long-term costs and potential savings based on your service tier.
- Setup and management: Consider ease of setup, mobile app support, and parental controls if needed for a household with kids or multiple users.
- Future provider changes: Some models list up-to-date compatibility; check provider pages for the latest supported speeds and firmware notes before purchase.
