I would say, the previous Arris SURFboard SB6190 Modem we reviewed on this website left us a mixed impression. It is well-built, cheap, and has lots of features, but our only complain is the use of Puma 6 chipset which is known for latency issues. Now, in this review, we look at a new Arris SURFboard product, the Arris SURFboard SBG8300. This one is pretty on the high-end side, so it’s a bit expensive but has all the modern features which we hope will be worthy enough for your hard-earned pennies.

Features of Arris SURFboard SBG8300
The Arris SURFboard SBG8300 is the second modem router combo on this website. If you have a Gigabit plan for supported cable networks, this is a must. It also has a good processor that can allow for a faster and more reliable connection. The following are the features that you would be getting in this $300 cable modem router combo device.
1. Multi-Processor Technology
While no mention of the specific processors inside, the Arris SBG 8300 features a multi-processor technology, based on ARM and ATOM application processor. That means, there is more than one processor inside to handle all the processes at once. Paired with DOCSIS 3.1 technology, the Arris SURFboard SBG8300 can handle multiple 4K and HD video streaming, as well as virtual reality without jitter or buffering.

2. DOCSIS 3.1
The Arris SURFboard SBG8300 is built upon the more modern DOCSIS 3.1. It’s an improvement from the previous technology and can support much faster internet speed plans, supporting 2x 196 MHz OFDM and 2x 96 MHz OFDMA channels. The best thing about this device is that it is backwards compatible with DOCSIS 3.0 just like its competitor Netgear C7800.
The Arris SURFboard SBG8300 can cover up to 3,000 sq. ft., and can connect up to 45 devices. Being a DOCIS 3.1 device, it will be able to support up to 10Gbps downstream, and up to 1Gbps upstream in the future. This makes it a more future-proof investment.
Channel bonding is also available for the device, up 32 downstream and 8 upstream channels specifically. Basically, what channel bonding does is combine all the speeds from each channel if your network throttle down the speed during peak hours. This is to make sure that you retain the speed you paid for.
3. AC2350 Dual-band Wi-Fi
The Arris SURFboard SBG8300 is also an AC2350 dual-band Wi-Fi, which means total throughput from 2.4GHz and 5GHz Wi-Fi maxes out at 2350Mbps.
If you don’t know the difference between the two technologies, see the bullets below.
- 2.4GHz can cover a larger area but is slower than 5GHz
- 5GHz is faster than the 2.4GHz but has less coverage area
Since the SURFboard SBG8300 is a dual-band router, you can also run several connections in 3×3 or 4×4 across the 5GHz band with MU-MIMO antenna arrays. However, your device needs to be in a line of sight with the router to be able to take advantage of this.
4. 4 Gigabit Ethernet ports
The Arris SBG 8300 can handle Wi-Fi with such a breeze. However, if you want a more stable Gigabit speed, a wired connection will be able to deliver that. Thankfully, the Arris SURFboard SBG8300 offers 4 Gigabit ports at the back of the device. You can use these Gigabit Ethernet ports for direct cable connection to a computer, game console, television, or streaming player.
5. SURFboard Manager App
Arris has a SURFboard Manager app available for both Android and iOS to monitor and manage your in-home Wi-Fi network straight from your mobile device. From the app, you can learn which location in your house has a weak Wi-Fi signal so you can improve signal quality through strategic Wi-Fi network extender placement. You can also run and save speed tests between your Wi-Fi device and the Access Point to check if speed issues are caused by the Internet or your home Wi-Fi network. You can also link the Arris SURFboard SBG8300 to the SURFboard Home Wi-Fi Management Alexa Skill for easier diagnostics and configuration.
The Arris SURFboard SBG8300 is a little bit on the expensive side. While the pros out win the cons, it is really hard to recommend for people who are still using an older Arris SURFboard with DOCSIS 3.0. Don’t get us wrong, the Arris SURFboard SBG8300 is future-proof, but unless you plan on upgrading or is currently subscribed to Internet plans faster than 400Mbps, there is no reason to spend this huge amount of money.
But if you think you have the budget to spend on this device, the Arris SBG8300 will be a good buy. It is built on faster and future-proof DOCSIS 3.1, with support for 32 downstream and 8 upstream channels on DOCSIS 3.0 mode. The four available Ethernet ports also make it easier for you to connect your devices directly to the cable modem router. However, the lack of USB port support will make it a deal-breaker for many. Especially those that want to use this in office space, with centralized USB printer or other devices.
The multi-processor technology is also something you don’t see on any other cable modem router combos. This makes it easier for everyone to connect to the network while watching high data contents like 4K and HD videos without jitter or buffering.
Arris also developed an app that is available for both Android and iOS devices. Yes, the SURFboard Manager app is currently mediocre, but the developers at Arris is working really hard to fix the current issues. In fact, some of the more major issues are already fixed.
