Our take on the NETGEAR C3700-100NAS N600 Cable Modem Router

The NETGEAR C3700 combines a DOCSIS 3.0 cable modem and a dual-band N600 Wi-Fi router in one box. It bonds 8 downstream and 4 upstream channels for modem speeds up to 340 Mbps and adds 2.4 GHz and 5 GHz Wi-Fi, two gigabit Ethernet ports and a USB 2.0 port for sharing a drive or printer. It suits households on modest cable plans that want to drop a separate modem and router. Against current DOCSIS 3.1 rivals it is dated: no Wi-Fi 5 or 6, one internal antenna and a 340 Mbps ceiling, so faster plans are wasted on it. Owners of the era found it easy to set up and reliable for everyday browsing and streaming, but weak at range and throughput by today's standards.

About the NETGEAR C3700-100NAS N600 Cable Modem Router

The NETGEAR C3700 is a cable modem and WiFi router in one device. It combines a DOCSIS 3.0 modem with a dual-band N600 router, so it can replace separate equipment. The modem supports speeds up to 340 Mbps and uses 8x4 channel bonding (8 downstream and 4 upstream channels).

The router broadcasts on both 2.4 GHz and 5 GHz bands, which lets devices be spread across the two bands to reduce interference. It has two Gigabit Ethernet ports for wired devices and a USB 2.0 port for sharing a storage drive, printer, or other peripherals on the network. It also includes DoS attack prevention.

It is certified to work with major cable Internet providers, including XFINITY from Comcast, Spectrum, and Cox. Xfinity customers can self-activate it. It is not compatible with cable bundled voice services. Charter certification is in process, so Charter customers should confirm compatibility before use.

Questions and answers

Is the C3700 worth it over a separate modem and router?
For a small home on a modest cable plan, one box is simpler and takes less space. A separate modem plus a modern router gives better Wi-Fi and more ports.
Does it work with my cable provider?
It is certified for major US cable providers including Xfinity, Spectrum and Cox. Check your provider's approved modem list before buying.
What internet speed can it handle?
The modem tops out at 340 Mbps with 8x4 channel bonding. Plans faster than that will be limited by the modem.
How many devices can connect?
It has two gigabit Ethernet ports plus dual-band Wi-Fi for wireless devices. Households with many devices will feel the limits of N600 Wi-Fi.
What is the USB port for?
It shares a USB storage drive or printer across the network. It is USB 2.0, so large file transfers are slow.
Does it support Wi-Fi 6?
No. It uses dual-band N600 Wi-Fi (802.11n), which is older and slower than Wi-Fi 5 and Wi-Fi 6 routers.
