ARRIS SBG8300 DOCSIS 3.1 Modem Reviews

With the ARRIS SBG8300 you can replace your existing rented modem and save $12 or more a month. It nearly pays for itself within a year. The SBG8300 has a built-in WiFi router that operates at 2350 Mbps with a wired connection. Wireless transmissions depend on the number of devices operating. The distance between the modem and device also matters to your wireless speed.

The ARRIS SBG8300 is compatible with XFINITY, Spectrum, and more cable operators. The main difference between the SBG8300 and all the other ARRIS modems is that it is DOCSIS 3.1 compliant. The modem itself can handle speeds up to 4 Gbps.

Design & Build

The SGB8300 is a router that measures approximately 10x8x3.7 inches in size. The Surfboard’s sides and front resemble a typical router, although the backside has a little more personality. Color coding rather than symbols or words is used in each section. The red area houses the Ethernet ports, while the yellow ones are located inside it. The coaxial cable connector is housed in the blue sector, while the power port can be found in the green sector. If you are colorblind, this system may not be as easy to use.

Many routers have a lot of LEDs on the front for detecting network issues. The SBG8300 is not like that. Onboard, there are only two lights. They can only tell you if the Surfboard is connected to the internet and whether your Wi-Fi signal is broadcasting properly. This design is quite easy to understand. You’ll need their app in order to get further diagnostic assistance.

The back of the router has four gigabit Ethernet connections. Each Ethernet connection is a genuine gigabit port. This implies that each of these connections may provide a lot of bandwidth. They’re ideal for situations where latency must be prioritized due to limited bandwidth, such as gaming consoles, smart TVs, and other connected devices.


The Arris SURFboard SBG8300 is a DOCSIS 3.1 device. This is an improvement on the previous technology. It accommodates higher internet speeds, with support for 2x 196 Mhz OFDM and 2×96 Mhz OFDMA channels. This gadget, like the Netgear C7800, is backward compatible with DOCSIS 3.0. The Arris SURFboard SBG8300 can cover up to 3,000 square feet. It supports up to 45 devices and connects up to 10 Gbps downstream and 1 Gbps upstream in the future. It’s a future-proof investment since it’s a DOCIS3.1 device that will support up to 10Gbps downlink.

The device can also bond with up to 32 downstream channels and 8 upstream channels. The term channel bonding refers to the process of combining all speeds from multiple channels, even though network congestion occurs during peak hours. This is done in order to ensure that you receive the speed you purchased.

AC2350 Dual-band Wi-Fi

The Arris SURFboard BG8300 has dual-band AC2350 Wi-Fi. This means that the total throughput of both 2.4GHz and 5.GHz Wi-Fi is 2350Mbps. The bullets below will help you understand the differences between these two technologies.

  • Despite the fact that 2.4 GHz covers a greater area, it is slower than 5 GHz
  • 5 GHz is faster than 2.4 GHz, it only covers a smaller area

Although MU-MIMO antenna arrays may be used to connect multiple devices to the Arris SBG8300 dual-band router operating on the 5GHz band, you must have your device within a direct line of sight of the router in order for all connections

“Future-proof your network with the SURFboard SBG8300. DOCSIS 3.1 WiFi cable modem, the latest standard offered by cable internet providers. It’s capable of bonding up to 32 downstream and 8 upstream DOCSIS 3.0. Or 2 x 2 OFDM DOCSIS 3.1 channels, providing increased bandwidth for true gigabit-speed capability. It’s perfect for gigabit-speed internet plans. As more cable providers upgrade the services to offer DOCSIS 3.1, your network will be ready with the SBG8300.” – ARRIS SURFboard

Port Management

You get four Ethernet connections, each with a different 1 Gbps speed. Feed each of the available wired connections straight into the machine if bandwidth is an issue. This may be a problem if you require the highest latency and bandwidth possible. If streaming or gaming are your preferred activities, this gadget may not be suitable for you. Additional slots must also be considered, which allow for the power and coaxial connection inputs.

It’s Easy to Use

Most people aren’t particularly interested in router technology. The ARRIS Surfboard SBG8300 is built to make things simpler for you. They do this in two ways. App assistance is the first, which isn’t surprising. Their app is comparable to the NETGEAR app in terms of features and functionality. You don’t need to download any software. You may customize it using any PC connected to the network. To control password settings or establish your own security measures, use parental controls.

It’s worth noting that the SBG8300 is built to last. It has been designed for DOCSIS 3.1, which means it is expected to operate for at least ten years. Even after new technology and standards changes occur, this router will continue to function. You don’t want your modem and router in the same location. If one of these components fails, the other will follow suit. Instead of just replacing one thing, you’ll have to replace them both now that they’re together.

These kinds of errors are extremely unusual. The convenience of dealing with only one gadget is offered by these all-in-one router/modem combinations. When it comes to security features, this device is rather basic. It lacks any business-related capabilities or extra VPN assistance. If you’re a regular user, you’re likely to wind up saving money in the long run.
