The ARRIS G54 is a powerful cable modem and WiFi router combo designed to deliver very fast internet speeds using the latest DOCSIS 3.1 standard and WiFi 7 technology. With a maximum speed of up to 18 Gbps and coverage reaching around 5,000 square feet, it suits large homes or users who want strong WiFi throughout their space. It has four standard 1-Gigabit Ethernet ports plus an ultra-fast 10-Gigabit port, helpful for connecting wired devices like gaming consoles or smart TVs.

This modem-router is compatible with major internet providers such as Xfinity, Spectrum, and Cox, which makes it a convenient choice if you use one of these services. One bonus is that owning this device can save you rental fees charged by ISPs. The product is praised for its speed and reliable connection; however, its size is a bit larger than some models, which may affect placement options.

If you’re looking for a high-end modem-router combo that prepares your home for future internet demands and want to avoid monthly rental costs, the ARRIS G54 is a strong candidate. However, if you have a smaller space or don’t need top-tier speeds, this might be more than necessary.

The ARRIS G20 Cable Modem Router Combo is a strong contender in the market, boasting DOCSIS 3.1 technology, which is significantly faster and more secure than the older DOCSIS 3.0 standard. This modem can deliver speeds of up to 1.0 Gbps, making it suitable for high-speed internet needs, including gaming, streaming, and large downloads. The inclusion of WiFi 6 (802.11ax) ensures better performance and efficiency, supporting numerous devices with minimal lag and higher speed.

Channel bonding capabilities enhance its performance further, with multi-gig networking potential for future-proofing your home network setup. The device also features dual-band frequency, enhancing its range and reducing interference, making it suitable for medium to large homes. With multiple Ethernet ports, it provides flexibility for wired connections critical for gaming consoles and PCs. Compatibility with major ISPs like Comcast Xfinity, Cox, and Spectrum makes it versatile and user-friendly.

Additionally, the SURFboard Central App simplifies setup and provides useful features like real-time network monitoring, parental controls, and guest mode. However, it's important to note that performance can be ISP-dependent, especially the optimized upload speeds. The relatively high price point might be a drawback for budget-conscious users. Some users have reported occasional connectivity issues, which could be a concern for those requiring constant and reliable internet access. Nevertheless, the ARRIS G20 offers a solid package for those looking for a high-performance cable modem router combo with modern features and robust capabilities.

The NETGEAR Nighthawk CAX80 is a strong choice if you want to combine your cable modem and WiFi router into one device, especially if your internet plan is with major cable providers like Xfinity, Spectrum, or Cox. It uses the latest DOCSIS 3.1 standard, which means it can handle internet speeds up to 2 Gigabits, making it well-suited for fast, modern internet plans. The built-in WiFi 6 technology (also called AX6000) offers fast wireless speeds up to 6Gbps and good coverage around 3,000 square feet, easily supporting 45 or more devices at once. This should be enough for most homes, even those with many connected gadgets. The device provides versatile wired connections including one 2.5 Gigabit Ethernet port and four standard Gigabit Ethernet ports, useful for gaming consoles, computers, or smart home hubs requiring stable and quick connections.

For security, it supports common WPA/WPA2 wireless protocols, protecting your network from basic threats. However, it is not compatible with fiber or DSL internet services from providers like Verizon or AT&T, so it’s only for cable internet users. Also, while it covers a good area, very large homes or thick walls might reduce WiFi performance. The unit replaces rental equipment, which can save you money over time. If you have a cable internet plan and want a future-ready, fast, and multi-device-friendly device with solid wired options, the NETGEAR Nighthawk CAX80 is a reliable and cost-effective choice.
