It’s doable for many cable internet plans, and the process is fairly straightforward.

1. Confirm compatibility: Check your provider’s approved device list and the product page for compatibility notes. On this page, you can also filter by compatibility to narrow options.
2. Pick the right device: Match the DOCSIS version and speed rating to your plan. If you use bundled home phone service, look for voice‑enabled models. Decide between a modem‑only unit or a modem‑router combo.
3. Activate the modem: Connect it, then follow your provider’s activation steps (online portal, app, or phone). Have your account info and device IDs handy.
4. Return rented equipment: Send back any leased hardware to avoid ongoing fees and keep the return receipt.

Steps can vary by provider and location, and results may differ based on your home setup.

Gateway models change frequently, so the most reliable info comes directly from your provider.

• Check your account: Sign in and look for an “Equipment” or “Devices” section that lists the current model or available upgrades.
• Visit support pages: Many providers publish approved device lists or gateway model guides.
• Ask support: Chat or call to confirm the latest model used in your area and how it compares to approved retail devices.
• Look at your current unit: The underside label usually shows a model name you can reference.

Use that info to compare features—DOCSIS version, Wi‑Fi technology, and Ethernet port speeds—when browsing options here. Availability and features can vary by region.

Both routes can work well, and the right choice depends on your priorities.

• Renting a gateway: Typically offers plug‑and‑play setup, included support, automatic updates, easy swaps if hardware fails, and integration with add‑ons like home phone. Tradeoff: ongoing monthly fees and fewer customization options.
• Buying your own: Lets you avoid monthly rental charges and choose features you want (e.g., DOCSIS 3.1, Wi‑Fi 6, 2.5G Ethernet, mid/high‑split support). Tradeoff: you handle setup and troubleshooting, and support from the provider may focus on connectivity rather than device settings.

Match your plan speed, home coverage needs, and how comfortable you are managing equipment. Results can vary by home layout, interference, and network conditions.

Pricing varies based on features and form factor. Consider these factors before you buy:

• DOCSIS version: DOCSIS 3.1 devices generally cost more than 3.0, reflecting newer capabilities.
• Speed rating: Higher throughput and more channels typically increase price.
• Modem‑only vs gateway: Combos add built‑in Wi‑Fi for convenience and may cost more upfront, but replace a separate router.
• Ports: Multi‑gig (2.5G) and additional LAN ports can add cost.
• Voice support: Models that support home phone service often price higher.
• Condition and warranty: New, restored, or refurbished options and warranty length influence total value.

Compare total cost of ownership with any monthly rental fees. Check the product page for current availability and use filters for compatibility, speed, and Wi‑Fi features.

Choose based on your plan speed today and how much you want to future‑proof.

• DOCSIS 3.0: Often a solid fit for modest plans (up to a few hundred Mbps) and widely supported by many providers.
• DOCSIS 3.1: Typically required for gigabit and multi‑gig tiers and can offer better efficiency, lower latency, and OFDM channel support. Many newer models add 2.5G Ethernet and upstream enhancements (e.g., mid/high‑split) that may help with future upgrades.

If you expect faster service later, 3.1 can be a more flexible choice. Always confirm your provider’s approved list and match the device to your plan. Real‑world performance depends on network conditions, home wiring, and placement.
