It supports the latest DOCSIS 3.1 standard, which means it's ready for the fastest internet plans today and offers some future-proofing for when internet speeds increase. It’s approved for major ISPs like Comcast Xfinity, Cox, and Spectrum, so compatibility shouldn’t be a problem for most users.

The built-in AC3200 Wi-Fi router supports dual-band frequencies (2.4 GHz and 5 GHz) and uses advanced features like beamforming and Power Boost to help your Wi-Fi reach farther and stay more reliable. This makes it a good fit for homes with multiple devices like gaming consoles, smart TVs, and smartphones. It also includes a useful mobile app for easy setup, guest network management, parental controls, and security alerts, which is great if you want a simple way to manage your network.

Some users note the device is a bit bulky compared to separate units, and since it combines a modem and router, if one part fails, you’ll need to replace the whole unit. However, owning this device can save you money on rental fees from your ISP, which adds up over time. For average home users wanting good Wi-Fi coverage and speed without extra hassle, the MG8702 is a practical and dependable combo device that supports high speeds and major providers.

Additionally, the inclusion of NETGEAR Armor software adds a layer of security, protecting your network and devices from potential threats.

The setup process is user-friendly, thanks to the Nighthawk app, making it accessible even for those who aren't very tech-savvy. However, it's important to note that this device is specifically designed for use in the U.S., which means international users will need to look for alternatives.

However, it's important to note that the modem is intended for use only in the US, which limits its applicability for international users. Potential buyers should also consider that while the product has a strong customer rating of 4.3 out of 5 stars, any network device's performance can be influenced by external factors like the quality of the ISP service and home network setup. In summary, the NETGEAR Nighthawk CM3000-1AZNAS is a powerful and cost-effective solution for those seeking fast and reliable internet speeds compatible with top US cable providers.
