Upgrading your WiFi router and cable modem is the single most effective way to improve your internet experience. It is also a clever way to cut costs, considering that most internet providers charge a subscription charge to lease them. The best modem-router combos for cable internet will do the same function as these two devices for a fifth of the cost, and with significantly fewer cords and power outlets.

It is not quite that basic, though. Not all modem-router combos work with all Internet Service Providers (ISPs), so be sure to buy a compatible one. You can find this information in your service contract or you can call your ISP directly for confirmation.

To make this decision-making process even easier for you, we will be discussing the best modem-router combos for cable internet in this blog post.

if speed is your main concern, then the Netgear Nighthawk CAX30S just might be what you need. It is a complete game-changer for your internet needs – which is why we strongly recommend this for heavy online gamers.

Netgear Nighthawk CAX305 establishes a dependable connection between your devices and the modem-router endpoint. It comes with WiFi 6 technology that ensures 4 times more capacity. Although it may not be the latest in the market, it is still pretty good.

Now, combine this technology with speeds up to 2.7 Gbps and you’ll be shocked to see its ultrafast connectivity and the power to eliminate dead zones.

That said, here is our overview of its pros and cons:

2. Arris Surfboard G54

We can’t help but mention Arris Surfboard G54 while discussing the transformative wave of WiFi 7. The name in itself speaks of cutting-edge connectivity. Because of its overall performance, durability, and innovative technology, we consider it one of the top picks of 2024.

If money is not an issue for you, then don’t let anything stop you from giving it a chance.

3. ARRIS SBG7600AC2

  • Modem Type: DOCSIS 3.0
  • Ethernet Ports: Four
  • Compatible Providers: Cox, Spectrum, Xfinity

ARRIS SBG7600AC2 is popular for its efficient setup and reliability. It is worth appreciating the strength of its signals, and improved speeds. Although it may not have the latest technology in the market, it fits perfectly wherever you place it.

What we like the most about it is that it can handle the internet traffic pretty easily. Its gigabit Ethernet ports allow you to take advantage of the built-in AC2350 Wi-Fi 5. And, it’s not only us who are fond of it, numerous major cable internet providers also approve it for its superfast speeds.

While we are completely sold on its performance, we are not entirely on board with its price - considering it doesn’t utilize the newest technology.

4. Arris Surfboard G34

Arris Surfboard G34

if speed is what you are in for, then the Arris Surfboard G34 is an ideal choice. It immediately upgrades your home network with its smooth Wi-Fi 6 technology. It also features four 1-Gigabit Ethernet ports – allowing you to connect your wired devices.

Plus, this modem-router combo comes with a compatible Central mobile app for a secure and instant setup. We believe Arris Surfboard G34 is best for connecting multiple devices to your home internet at the same time due to its DOCSIS 3.1 technology and capacity.

We love its advertised speeds and technology but we do wish Arris Surfboard G34 works more on its connectivity issues. The device sometimes requires you to reset it for it to continue working smoothly.

Our Top Pick

After analyzing the overall performance, speeds, technology, and price point of each modem-router combo, we have decided to pick Arris Surfboard G34 as our shining star. It comes with the best mid-range price, solid features like dual-concurrent AX3000 Wi-Fi, which enhances your online experience, and the latest technology. But, keep in mind that it may pose some connectivity issues with its device.

We would also like to reiterate that before investing in any device, make sure that it is compatible with your ISP. For any further assistance, contact our expert customer service team at (855) 573-1435.

Frequently Asked Questions

While purchasing a modem-router combo, make sure that it has the connectivity that suits your digital lifestyle. Look for its WiFi model, the number of its Ethernet ports, and its compatibility with your ISP.

Generally, a modem-router is considered outdated if it is more than five years old. During this period, the technology has advanced significantly, and it may not even support some of the security features.

For the purpose of upgrading your home network, you can plug in a router to an existing modem-router combination unit through an Ethernet port.
