The Review
It is strictly a cable modem offering gigabit connectivity support. You don’t have to purchase a standalone router as the gadget also doubles down as a standard Wi-Fi router with an equivalent speed limit of 2350mbps.
In this detailed review, I shall take every aspect of the Arris SURFboard SBG8300 into account whilst coming up with inferences supporting or opposing the adoption of this modem-router combo, based on the internet service package, highest speeds offered by the ISP, and the willingness to future-proof the setup.
Design & Build
The upright layout of the Arris SURFboard SBG8300 is worth applauding as it doesn’t sit through like a usual, horizontally-aligned device.
While the gadget weighs slightly north of the 3-pound mark, the overall design is strictly conventional yet eye-pleasing. Starting with the rear, the color labeling strictly adheres to the port arrangement, with yellow showcasing Ethernet slots encapsulated within a reddish space. Besides, it also has a separate section for the coaxial cable and a dedicated power port.
In case you are concerned about the lights or LEDs, the Arris SURFboard SBG8300 offers two separate indicators. Each of these LEDs showcases the functioning of the Arris SBG8300. They also showcase the strength or persistence of the Wi-Fi signals, traffic availability, and more.
Port Management
As far as the output slots are concerned, you get access to four dedicated Ethernet ports, each having a certain kind of gigabit capability. Therefore, if bandwidth is your concern, each of the available wired connections can be directly fed into the machine. However, the closeness of the ports happens to be an issue in case you are reliant on improved latency against the highest possible bandwidth on offer.
Therefore, this might just be the wrong device to purchase if streaming and gaming are your preferences. Besides, there are two additional and requisite slots to account for, rendering support to the coaxial cable connection and the power cable.
The Compatibility
Before we start talking about the compatibility issues, it is important to gauge the possibilities and competences of the gadget.
Firstly, The Arris SurfBoard SBG8300 is only compatible with cable internet clients, including Spectrum, Cox, and Xfinity.
However, it is not advisable to purchase this gadget if your ISP provides internet services via Fiber cables. Therefore, the likes of CenturyLink, ATT, Verizon, and other DSL ISPs are incompatible and do not sync at all with the Arris SURFboard SBG8300.
Then again, the maximum and supported ISP speeds vary depending on the hardware and architecture of the concerned network. For instance, COX internet service providers can keep up with this combo for 4gbps or speeds lower than that.
The same ballpark extends for the Xfinity service providers. On the other hand, Spectrum allows you to get maximum modem speeds of up to 1gbps, or slightly slower. Regardless of the usage, it is advisable to cross-check the ISP compatibility and the supported plans to confirm compatibility.
Hardware & Technology
When it comes to the associated technologies, the Arris SURFboard SBG8300 boasts of a pretty extended palette, comprising of the following:
1. DOCSIS 3.1
Firstly, we shall be keeping the review and relevant explanation simple to ensure every individual understands the associated technologies. The SBG8300 is among the best-rated DOCSIS 3.1 modems.
The DOCSIS 3.1 technology is best attributed to the OFDM and OFDMA, 2×2 channels, which in turn ensure better traffic transmission whilst keeping attenuation, frequency fading, and other issues at bay which is a reasonable improvement over the previous DOCSIS 3.0.
The 2x196MHz OFDM channels also ensure backward compatibility, especially if you are in the market for a backward-compatible device. However, we shall be discussing the DOCSIS 3.0 compatibility, and channel spread later in the discussion.
When compared to the Netgear C7800, the backward compatibility is reliable and in line with the better speeds and channel width.
Besides, the Data Over Cable Service Interface Specification or DOCSIS 3.1 standard allows your network to reach the highest possible speeds of up to 10gbps, provided the router, and the ISP is capable enough of handling the same.
Read our DOCSIS 3.0 vs 3.1 comparison if you’re interested in learning the differences between both the technologies.
2. Dual-Band Wireless Technology
Despite the highest possible speed limits supported by the Arris SURFboard SBG8300 modem, it is necessary to understand that the wireless network technology throttles the same to a maximum of 2350mbps. While the Wi-Fi AX (WiFi 6) technology is amiss, the dual-band technology takes care of the existing speeds.
Therefore, the router can automatically juggle between 3×3 or 4×4 band selections to automatically offer the best speeds over the 2.4GHz and 5GHz bands.
When compared to the Netgear C7800 that features 4 dedicated antennas regardless of the band, Arris SBG8300 allows you to use the 3×3 or 4×4 antenna arrays, based on the requirements.
3. MU-MIMO Technology
As far as antenna technology is concerned, it is the MU-MIMO that comes under consideration. This technology empowers the gadget to use multiple data streams, 3×3 or 4×4, in the case of the Arris SURFboard SBG8300. Paired with Wi-Fi AC, this technology allows the combo gadget to connect multiple devices at once, especially when high-density internet networks are concerned.
4. OFDM and OFDMA
These adequately comparable technologies allow the device to access beefed-up carriers, based on the time domain and even frequency domain in case of the latter or the OFDMA technology. Put simply, these DOCSIS 3.1 sub-premises ensure that modem-router combo can selectively check the best-in-class data carrier and transmit traffic, accordingly, in case there is some sort of network congestion for single carriers.
5. IPV6 Compatibility
The latest IP protocol associated with the Arris SURFboard SBG8300 comes with a host of benefits, including support for auto-configuration and improved multicast routing, if and when necessary. In case you are looking to make the best use of the QoS, IPV6 comes forth as a reliable resource. Despite being an inherent technology, IPV6 compatibility speeds up routing and ensures that the lack of NAT or Network Address Translation support in the absence of USB ports is never an issue.
6. Wave 2 technology
Here is a wireless addendum that takes 160MHz bandwidth into consideration, unlike the single band carriers, like 20MHz, 40MHz, and 80MHz, respectively. Wider channel ensures larger bandwidth, allowing the Arris SURFboard SBG8300 router to connect with several gadgets at once whilst encouraging better wireless performances.
7. Processor
As far as the processing conglomerate is concerned, Arris SURFboard SBG8300 involves multiple chipsets for handling modulation-demodulation and even the wireless routing to the best of its capabilities. The inclusion of the ATOM processor and ARM chipset ensures that the modem and even the integrated router manage to handle multiple processes with ease.
The powerful processor works alongside the DOCSIS 3.1 technology and allows you to stream 4K videos with precision, provided the ISP accommodates the same.
In case you have a VR ready computing resource in play, the Arris SURFboard SBG8300 processor takes the jitters and lags out of the way. Most importantly, the processor and coprocessor ensure that connecting multiple devices is never an issue.
8. Channels
The DOCSIS 3.0 backward-compatible technology makes room for the Channel Bonding technology via the 32 x 8 downstream and upstream configuration.
The best thing about the channel bonding support is that the Arris SURFboard SBG8300 uses multiple packets to transmit internet traffic in the most harmonious manner without getting affected by congestion and latency.
The 32×8 channel bonding support across the DOCSIS 3.0 standard ensures that the modem always has multiple lanes for transmitting data packets. Clubbed with the MU-MIMO antenna support for the routing segment of the device, the Arris SURFboard SBG8300 ensures the fastest possible connections with zero lags and interferences to account for.
When the Arris SURFboard SBG8300 is concerned, 2 adjacent channels, downstream and upstream, work in cohesion to increase the overall throughput.
Most importantly, this technology also extends to the Ethernet connections as the single-port bandwidth can be deployed in unison to increase the available speeds, provided the ISP permits the same.
9. Speed
For speed-related issues, this gadget is capable of supporting up to 10gbps download speeds and 1gbps when upload speeds are concerned. Therefore, if you are considering connecting the computing device via the Ethernet ports, you can get speeds of up to 4gbps, provided the ISP has the technology to offer the same.
However, the router comes with dual-band Wi-Fi AC technology at the helm, allowing you to reach decent speeds for the 2.4GHz and 5GHz bands.
According to experts, the Wave 2 wireless standard supports close to 1900mbps for the 5GHz band under ideal circumstances. However, the available speeds are close to 700 to even 900mbps ballpark. The 2.4GHz allows you to reach speeds close to 200mbps, which helps you reach gigabit speeds even while taking attenuation into account.
10. Range
When it comes to the router range, the Arris SURFboard SBG8300 is capable of covering almost 3000 sqft of open and enclosed space. Despite the highest possible range, it is the MU-MIMO wireless technology and followed by the Wave 2 compatibility that determines the functionality and quality of the connections.
Most importantly, the 3×3 antenna support for the range-independent 2.4GHz is an excellent addition as it works efficiently with the dual-band and concurrent wireless standard to be able to connect almost 45 devices at once.
While you might never be able to take complete advantage of the underlying technologies and the bandwidth-centric potential of this router due to the restricted ISP plans, it isn’t advisable to pair the same with an extender.
11. Modem Functionality
As a DOCSIS 3.1 compatible modem, the Arris SURFboard SBG8300 features a host of additional resources, as compared to a DOCSIS 3.0 variant! As far as the throughput is concerned, the 4096QAM technology allows you to assume close to 1.86Gbps for each 192MHz channel.
Developed by CableLabs, the concept of DOCSIS 3.1 is precisely meant for future-proofing your home and office setup. Therefore, even though the Arris SURFboard SBG8300 doesn’t support fiber cable, the coaxial connection speeds are still worth it, considering the role of ISP.
However, if your internet service provider like COX has the Gigablast plan or other high-bandwidth packages to rely on, the DOCSIS 3.1 seems like a pretty good choice. Besides, this modem also uses the data spectrum wisely and efficiently while offering a wider transmission channel to send across additional data packets to combat congestion.
Moreover, if you do not want to use the router functionality, the 4 gigabit Ethernet ports can be directly connected to the device to make the most of the channel bonding technology. However, channel bonding works the best if you have connections from different ISPs to consider, as you cannot achieve speeds that a standalone ISP doesn’t guarantee.
12. Router Functionality
As a router, the Arris SURFboard SBG8300 is no pushover, despite the lack of full-fledged Wi-Fi AX support. The dual-band wireless connectivity ensures that you can very well reach real-time speeds of up to 1gbps. Moreover, you can either use the same gigabit Ethernet router or a standard wireless router with ideal speeds close to 2.30gbps.
Then again, it is necessary to get the device firmware updated to ensure that the modulating-demodulating and routing segments work just fine. The Wi-Fi range at close to 3000sqft is more than acceptable, but pillars do contribute to speed, and connection drops as reviewed by our experts,
In case you want to pair an extender, the device latches onto the 2.4GHz and 5GHz spectrum, thereby lowering the speeds. Router functionality can be determined by the front-facing lights and LEDs.
