10 Best Xfinity Modems 2026 in the United States

The NETGEAR Nighthawk CAX80 is a strong contender in the modem category, particularly for users with cable internet plans up to 6Gbps. Its compatibility with major providers like Xfinity, Spectrum, and Cox makes it a versatile choice for many households. The built-in WiFi 6 router offers impressive coverage of up to 2,500 square feet, supporting up to 30 devices simultaneously, which is ideal for homes with multiple users. With its DOCSIS 3.1 standard and 32x8 channel bonding, users can expect reliable high-speed internet for activities like streaming or gaming, especially with the ability to aggregate two ports for ultra-fast connectivity.

It offers two Ethernet ports: a 2.5 Gbps port and a standard 1 Gbps port, giving flexibility for high-speed wired connections. This device is modem-only, so you’ll need to add your own Wi-Fi router if you want wireless network access at home. This separation can be a bit inconvenient if you prefer an all-in-one device but allows for more customization and potentially better Wi-Fi performance with a dedicated router.
