The dual-band setup helps manage network traffic better, reducing slowdowns during busy times.

The four Gigabit Ethernet ports are a plus if you want to connect wired devices like gaming consoles or smart TVs, and port aggregation can boost wired speeds when supported. However, this model is only compatible with major cable providers like Xfinity, Spectrum, and Cox, so if you use DSL or other types of internet service, this won’t work for you. Another helpful feature is NETGEAR Armor, which offers enhanced online security tools to protect your network from threats, though it comes with a limited free trial.

While it saves rental fees by combining your modem and router, some users might find coverage a bit limited if they have a larger home or many devices beyond the recommended number.
