Due to this, up-to-date equipment is necessary to accommodate multiple devices without reducing the speed of functionality. The Arris Surfboard SBG8300 contains three products; a DOCSIS 3.1 Cable Modem, AC2350 Dual-band Wi-Fi connection, and a four-port Gigabit Router.

The DOCSIS 3.1 Cable Modem employs modern generation technology. The AC2350 Dual-band Wi-Fi connection is the router equipment that is powerful enough to support a large household with multiple devices. This particular device is compatible with most United States Internet Providers such as Spectrum, Xfinity, Cox, and other cable connections.

Special features of Arris SBG8300 Review

The Arris SBG8300 is built to exhibit state-of-the-art technology with exclusive features. The 3-in-1 product is designed to improve connectivity and provide convenience for all the gadgets in the house. Here are some of the exclusive features of the product.

1.     Powerful processor

The Arris Surfboard SBG8300 is equipped with multi-processor technology based on ATOM and ARM application processors. This enables the processor in the router to handle multiple processes at the same time. The pairing with DOCSIS 3.1 enables the modem router to stream multiple HD and 4K videos.

The technology embedded in the Arris Surfboard SBG8300 can stream virtual reality without lag and jitter. This multi-processor technology allows a smooth and advanced experience even while multiple devices are in use at the same time.

2.  DOCSIS 3.1

This cable ISP is capable of offering support to faster internet speed plans. The DOCSIS 3.1 device can handle 10Gbps downstream. This means that it can handle 32 downstream and eight upstream DOCSIS channels. The router is also backward compatible with DOCSIS 3.0, which is considered one of the best features of this particular model.

Due to this technology, the Arris Surfboard SBG8300 can reach about 3,000 square feet and can connect 45 devices. Channel bonding is offered by this device, which allows the combination of all speeds from each channel if the speed is reduced during peak hours.

3.     AC2350 Dual-band Wi-Fi connection

Arris SBG8300

As mentioned earlier, the Arris Surfboard SBG8300 also offers AC2350 Dual-band Wi-Fi, which implies that it offers throughput of 2.4GHz and 5GHz Wi-Fi. This maxes out at 2350Mbps, which is still a large bandwidth for a wireless connection. This is an amazing combination, as 2.4GHz can cover a larger area while 5GHz is faster.

The AC2350 connections can run in 3×3 or 4×4 using the 5GHz band Wi-Fi with a MIMO or MU-MIMO antenna configuration. However, the MU-MIMO is functional only if your device is directly in the line of sight of the router.

4.     Ethernet ports

Even though the Arris Surfboard SBG8300 handles Wi-Fi effectively, it also offers facilities to create a more stable Gigabit speed. This is done through wired connections with the in-built Ethernet ports on the router. These ports are helpful when you need a direct cable connection to a television, computer, streaming player, or a game console.

The four Gigabit Ethernet ports present on the router can effectively draw up significant bandwidth from each of these connections. While the Ethernet ports are hidden at the back of the router, the front showcases a series of LED lights, which signify that your Wi-Fi is working.

5.     Accessible

The Arris SBG8300 allows a great amount of control over it. This model is capable of being incorporated into the smart-home network because it supports Alexa. This inevitably allows voice control over the router and increases convenience while using it.

With this feature, you can reset the router-modem without hassling with shutting off the power to other devices during this process. For more detailed changes in configuration or other settings, a desktop PC can be used or the Surfboard manager app.

6.     Surfboard manager app

Arris has its own manager application, which is available for both IOS and Android. This app can be used to manage the Wi-Fi network or understand the weakest Wi-Fi signal location in the house. With this feature, you can improve the signal to that particular spot using a Wi-Fi extender placement strategically.

In addition to this, the Surfboard manager app can implement parental controls and also creates numerous presets to enable a hands-off experience. Speed tests can also be run through the app to check and rectify Internet speed issues. Alexa can also be operated through this application.

7.     Durability

The Arris Surfboard SBG8300 is designed to function for at least a decade. This is because it employs the technology of DOCSIS 3.1, which is an adaptable format and forward-looking. Since the Arris Surfboard SBG8300 is a combination of a modem and router in one device, it makes it easier and more convenient to use.

The physical hardware may be a problem in the long run. If the modem or router dies, the other dies with it. Although it is unlikely, in this case, it is better to purchase a cable modem and router separately for a safer option. However, this reduces the convenience offered by the SBG8300.


  • Supports 10Gpbs downstream and 1Gbps upstream in the future.
  • The multi-processor technology facilitates better performance.
  • 32×8 channel bonding is supported.
  • Surfboard manager app that allows connection with Amazon Alexa.
  • Compatible with Spectrum, Cox, and Affinity.


  • A bit pricey for a cable modem router combination.
  • Does not have USB ports.
