Design

The NETGEAR C6300 has a slimmer profile than the C6250.

The NETGEAR C6250 (left) has a wide front face while the NETGEAR C6300 (right) is tall and slim.

Right away you’ll want to decide whether the leaning wide front of the NETGEAR C6250 is more to your liking or if the slim, tall design of the NETGEAR C6300 appeals to you more. Depending on where you’ll be placing your cable modem, their orientations will mean one is better suited than the other, although it’s probably easier to fit the C6300 in most places.

Both cable modem routers are dressed in crisp matte black, with perforations on the side for ventilation. Their rectangular forms are minimalist without being plain, which seems perfect for a functional device sitting in your living room. LED indicators are arrayed at the bottom of the C6250, while they’re diagonally placed on the C6300. These make it easy to check which bands and features are currently working at a glance.

Connectivity

The NETGEAR C6300 has more ports than the C6250.

The most noticeable difference here is that the NETGEAR C6250 (left) has half the yellow ports of the C6300 (right).

Behind each NETGEAR cable modem router are several ports for wired connections as well as the power cable. Most notably, the C6250 only has two LAN Gigabit Ethernet ports while the C6300 has four. This means you can plug in more devices, such as desktops and gaming consoles, for a more reliable wired connection. Both have auto-sensing technology so they can instantly detect what’s being connected and complete the connection without any settings adjustment.

Aside from the LAN ports, there’s also a USB 2.0 port on both NETGEAR cable modems, letting you plug in a storage device, printer, etc. The Coax port is where you’ll need to plug in the coaxial cable from your ISP’s connection. You’ll want to make sure that your coaxial cable is ready to be unplugged and plugged in to either modem router to ensure the setup process goes smoothly.

The NETGEAR C6250 and C6300 are compatible with most major cable Internet providers, including Xfinity by Comcast, COX, and Spectrum. They are not designed to be used with other telecom providers such as Verizon, AT&T, DISH, CenturyLink, DirecTV, and other DSL and bundled voice services.

Performance

The NETGEAR C6300 has a higher maximum speed than the C6250.

Despite the difference in specs, the NETGEAR C6250 proves very capable for most homes.

Since the NETGEAR C6250 is an AC1600 device and the C6300 is an AC1750, the theoretical maximum connection speed of the C6300 is that much higher. These cable modems use DOCSIS 3.0 for faster cable Internet speeds. Both are dual-band routers broadcasting in 2.4GHz and 5GHz, but while their 5GHz max is both 1300Mbps, the C6300 has a 450Mbps 2.4GHz band while the C6250 tops out at 300Mbps.

In practice, this means you’ll likely have the same outstanding 4K HD streaming and lag-free online gaming with both NETGEAR modem router combos since these intensive online activities utilize the high-speed 5GHz band. The higher 2.4GHz band of the C6300 should allow more devices to connect without any of them experiencing lag or buffering. Note that even though the C6250 has a max download speed of 300Mbps and the C6300’s is 680Mbps, both are technically capable of the higher limit and they are still subject to your cable subscription speed.

The NETGEAR C6250 and C6300 should provide sufficient coverage for most average-sized homes with its 1,500 sq. ft. coverage. You can connect up to 25 devices without needing to select which band they’ll be using, since the routers will intelligently choose for you. With 16×4 channel bonding, you’ll experience less congestion and optimal speeds even during peak hours.

Software and Other Features

The NETGEAR C6250 and C6300 have similar software features.

You can download the Nighthawk app to manage either NETGEAR cable modem router.

Setting up the NETGEAR C6250 and C6300 is easy and can be done by following the on-screen setup on your computer or using the Nighthawk app. This app further provides plenty of management and optimization features, including device management, network map, parental controls, speed checks, guest Wi-Fi setup, and home network security.

Advanced parental controls allow you to filter website content to protect your children from inappropriate sites on the Internet. You can also give guests temporary access to the Wi-Fi without compromising your home network access. For better security, your chosen cable modem router automatically gets NETGEAR Armor to block malicious threats targeting devices connected to the network.

Verdict

We recommend the NETGEAR C6250 over the C6300.

Despite the apparent advantages of the C6300, we still recommend the NETGEAR C6250 Cable Modem Wi-Fi Router Combo due to its price and availability. It’s the most affordable on NETGEAR’s lineup of cable modems and you can find a brand new one very easily at big box retailers. Performance-wise, it can provide top speeds as fast as the C6300 and includes the same features. The NETGEAR C6300 Wi-Fi Cable Modem Router is certainly more impressive with its beefier specs, and is definitely worth the extra if you have a high-speed cable Internet plan.
