Buying Guide: Key Purchase Considerations

  1. DOCSIS standard: For future-proofing and higher speeds, choose a DOCSIS 3.1 modem (e.g., CM1200, CM2050V) when your Xfinity plan supports multi-gig speeds. DOCSIS 3.0 remains a solid option for base-level plans.
  2. Modem vs. modem-router combo: If you want a single device to handle both modem and WiFi, consider a combo like CAX30 or ARRIS SBG7400AC2. If you already have a reliable router, a standalone modem (e.g., CM1200, CM500) may be more cost-effective.
  3. WiFi capabilities: For large homes or many devices, prioritize WiFi 6 (AX) models for improved performance and efficiency, especially with multiple concurrent streams and smart-home gear.
  4. Provider compatibility: Verify support for Xfinity and other providers you use. Some devices are explicitly certified for Xfinity Voice or Triple Play, which can influence your best choice.
  5. Future-proofing vs. budget: Higher-speed 2.5 Gbps or multi-gig devices are more future-proof but come at a higher upfront cost. Balance current plan speed with potential upgrades.
  6. Number of Ethernet ports and USB: If you rely on wired connections, look for 4x1G Ethernet ports and USB 3.0 for per-device connectivity and future expansion.
  7. Rental savings: Many modems offer the potential to save on monthly rental fees; compute long-term savings based on your plan and rental costs to justify an upgrade.
