The NETGEAR CAX30S is a DOCSIS 3.1 cable modem and Wi-Fi router, supporting internet plans up to gigabit speeds. It provides 4 x Gigabit Ethernet LAN ports, plus AX2700 Wi-Fi 6 wireless, for homes on gigabit cable internet plans. It is compatible with major US cable internet providers, so you can replace a rented ISP device with your own.
Why Owning Your Cable Modem Saves Money and Improves Reliability
Many cable internet customers rent a modem from their provider every month. Over a few years, those fees often exceed the cost of buying a modem, and rental units are frequently older models that cannot deliver the full speed of current plans.
The CAX30S uses DOCSIS 3.1 technology to support internet plans up to gigabit speeds, so the modem is not the bottleneck in your connection.
Because it combines a modem and Wi-Fi router, it reduces clutter and gives you one device to manage for both internet access and wireless coverage.
Speed and Compatibility
The CAX30S is compatible with major US cable providers such as Xfinity, Spectrum and Cox (check your provider’s approved device list). It supports plans up to gigabit speeds.
Built-in Wi-Fi Router
Its AX2700 Wi-Fi 6 radio covers a typical apartment or small home, with 4 x Gigabit Ethernet LAN ports for wired devices.
How to Set Up the NETGEAR CAX30S
- Connect the coaxial cable from your wall outlet to the modem and connect power.
- Wait for the power, downstream, upstream and internet LEDs to show a stable connection.
- Connect to the default Wi-Fi network printed on the label, or connect a computer by Ethernet.
- Activate the modem with your internet provider using its app, website or phone line, then restart the modem and test your speed.
