Buying vs. Renting a Modem and Router: Which Is Best?

Key Takeaways

• Overall Recommendation: Buying your own modem and router is generally the best choice for long-term cost savings, better performance, and more network control. For Spectrum users, keep the free modem from your Internet Service Provider (ISP) and purchase your own router to avoid monthly WiFi rental fees and improve overall network performance.
• Cost Savings: Renting a modem/router from an ISP can cost an extra $300/year; buying your own equipment typically pays for itself within 1–2 years. Spectrum offers a free modem, so there's no need to purchase your own unless you want full control. However, they charge for their WiFi router, which you can avoid by using your own.
• Performance and Features: ISP-supplied equipment is often basic or outdated, limiting speed and WiFi coverage. Buying your own router/modem allows for higher performance (e.g., WiFi 6/6E or DOCSIS 3.1) and better stability.
• Customization and Control: Privately owned equipment gives you full access to advanced features: custom configurations, device prioritization, parental controls, guest networks, and more robust security.
• WiFi Coverage: To eliminate dead zones in larger homes, consider a mesh WiFi system like TP-Link Deco or Netgear Orbi. Many find ISP routers lacking in range and speed, prompting upgrades to more powerful consumer-grade routers.
• When Renting Might Be Better: Short-term living arrangements (e.g., rentals or temporary housing). Less tech-savvy users who prefer ISP support and free equipment replacements. If your ISP includes equipment for free (like Spectrum’s modem), there’s less incentive to buy your own unless you want the best performance.
• Important Buying Tips: Ensure modem/router compatibility with your ISP, check their approved device list. Get a DOCSIS 3.1 modem (if using cable Internet) for future-proofing. Use separate modem and router units for flexibility and better performance (avoid modem-router combos unless high quality). Keep router firmware up to date to maintain speed and security.

Everyone wants fast Internet speeds, but not all Internet service providers offer the same packages. Many ISPs, including Comcast Xfinity, Spectrum, and Cox, offer their own equipment that you can rent for a monthly fee, but in most cases, you can also buy your own modem or router.

Let’s talk about which option is best.

Should I Buy My Own Modem and Router?

If you want the fastest WiFi speeds available and more control over your home network’s Internet connection, the cost of buying a new modem and router is worth the upfront cost.

Buying vs. Renting: Running the Numbers

Buying

Buying a new DSL or cable modem and router can cost anywhere from $50-$350 each. Or, instead of buying a separate modem and router, you can actually purchase a modem router combo for $300-$500.

The downside of buying is that your equipment will go through normal wear and tear, meaning you will eventually have to pay to replace both items. Most modems and routers are generally replaced about every 3-4 years.

Renting

Depending on the ISP you choose, renting can cost up to an extra $120-$300/year in equipment fees on your Internet bill.

In the long run, if you don’t buy the top-dollar, premium equipment, buying a modem and router is a more affordable option for high-speed Internet.

Do I Need an Expensive Modem or Router?

Buying your own equipment doesn’t have to be expensive, as you can easily buy your own modem or router from an online retailer such as Amazon.

Modems and routers are equipped to handle a certain amount of bandwidth, meaning you should check your Internet plan’s maximum Mbps download speeds before making a purchase. There’s no point in buying a super high-end device that you don’t even have the speeds to match!

Buying Your Own Modem

If you decide to buy your own equipment, make sure you buy a compatible modem. Cable Internet modems are categorized by a standard called DOCSIS. This standard is currently in its third generation. With each generation, the speeds become faster.

Some ISPs no longer allow DOCSIS 3.0, which means it is important to find a device that’s capable of DOCSIS 3.1.

If you aren't sure what to buy, make sure to contact your ISP to clarify before spending any money. Our top recommendations include:

• Arris SURFboard S33: High performance, DOCSIS 3.1.
• Netgear Nighthawk CM2000: Ideal for gigabit plans.
• Motorola MB7420: Budget-friendly, reliable option.

Buying Your Own Router

There are many great products on the market that can improve your connectivity.

Some of the benefits of buying your own WiFi router include warranties, potentially higher Internet speed, and you won’t have to rely on your Internet provider’s tech support if something goes wrong.

Our top recommendations are:

• ASUS RT-AX5400: WiFi 6 with strong performance.
• TP-Link Deco X55 (AX3000): Affordable mesh system for full-home coverage.
• Netgear Orbi series: Premium mesh solutions.
• Eero: User-friendly mesh option.
• Ubiquiti: Great for users who want advanced settings and enterprise-grade control.
