Review: Arris SBG8300 - Excellent Gateway, No Problems after 1 Week. - I purchased this ARRIS SBG8300 gateway new from desertcart for $177 in May 2024 to switch from AT&T DSL2+ (copper landline) to Sparklight cable internet service (100 MBps down/ 10 MBps up). I decided to purchase and own it myself, rather than pay rental fees- it should pay for itself in about one year. I wanted an established DOCSIS 3.1 design (3.1 is required by Sparklight) that could handle possible future cable bandwidth upgrades, and this gateway seemed good for that. It has 32 x 8 channels for DOCSIS 3.0 and 2 x 2 channels for DOCSIS 3.1, and can theoretically handle up to 4 Gbps download speeds, so this is probably way more gateway than I need now. The Sparklight installation tech told me that this was the first time he had encountered a new customer who provided their own gateway in my rural MS town. This turned out to be a minor problem, as he had always been given the gateways pre-configured. Initially, he was unable to get it up and running, and he had to run off to perform other installations (Uh-oh!). But the Sparklight phone support people were very good, and saw that the gateway was simply waiting for a firmware update. Apparently, firmware updates are something that only the cable company can do. Sparklight was able to push the update remotely, and I was off and running. Configuration was pretty straightforward. I should warn potential buyers that the gateway's firewall is set to WEAK by default. I decided to switch the firewall to MEDIUM, and discovered that I could no longer access the gateway configuration page directly using the http:// browser connection. After going to MEDIUM, it only allowed https:// browser connections. So, you have to go through a few extra clicks (accepting the risk, etc.) in the browser to reconnect to the gateway's configuration page. With all of the warnings, etc., it is easy to believe that your new gateway may have been hacked, so be prepared for that. Make sure that you turn off UPnP for added security unless you need that. It is also a good idea to do a port scan to make sure there are no unnecessary open ports that could present good targets for hackers. Performance has been excellent, delivering over the purchased speeds (usually, I get 110 Mbps download and 20 MBps upload via speedtest.net). I have not had a single problem after about 1 week of service, have never needed to do a reset, and the gateway seems to be running cool, just above room temperature. I think that most problems that people experience with cable modems/gateways in general are due to 1) poor line signal quality and 2) WiFi crowding/interference issues. The SBG8300 provides line quality information in the homepage, so you can troubleshoot signal issues yourself and perhaps avoid extra service fees if the problem is inside your home. I did not try the gateway configuration app for wireless devices- all of my tweaking was through a hard Ethernet connection and web browser. FYI the gateway homepage did complain about my Firefox version 126 (some warning about needing at least v 63) , but it worked OK. I guess that the only features that I wanted, but couldn't have using this gateway, are: 1) WiFi 6 - this gateway has the older WiFi 5 (802.11ac) standard . But our current wireless devices can't use WiFi 6 anyway, so no biggie. 2) No USB port on the gateway. This is very handy if you want to do network printing via USB, or set up a large USB stick as a network drive (NAS). Overall, I really like the performance of this gateway. Time will tell if the hardware is as reliable as it appears to be. ----------------------------------------------------------------------------------------------------------------------- 7/24 Update- No problems after ~ 60 days, very pleased. After doing a little more research, it turns out that there are some interesting reasons some cable modems fail. It all goes back to the original cable concept as a distribution system for ONE-WAY analog TV signals. Cable modems must both receive and send digital signals. If the DOWNLOAD line signal quality is poor, you will get disconnect/reconnect issues- everyone knows that. But the more serious issue is with the UPSTREAM signal. The cable modems will try to overcome poor line quality conditions by BOOSTING the UPLOAD signal. This leads to greater continuous heat generation inside the modem, and sometimes failure due to overheating. So, the reason some folks need to replace their cable modems regularly is due to the poor line signal quality, not necessarily the modem itself. You can fix this with a special amplifier called an active return cable modem amplifier (desertcart sells these), but the permanent fix is to get the cable company to change out the cabling and components to get a good baseline signal. Review: Works with Spectrum (in NC) - Read a few reviews saying this doesn't work with Spectrum. I'm not sure if Spectrum in other States might make it unusable but in my state, it works fine. It only took a few minutes BUT, I did have to call Spectrum for them to register it. I have noticed some on and off WiFi connectivity now. I don't know if it's Spectrum trying to get you to pay for their modem and their monthly fee or what. I would suggest turning off band steering. I left band steering on and I had intermittent WiFi cutting out. Another strange thing is the lights were blue when I first installed it and it was working fine. Now, after I had WiFi issues and unplugged and plugged it back in, the lights are green which is apparently the correct color. Oh well. So far it works. ## Features - Fast, Reliable Connection: Enjoy high-speed streaming, gaming, and browsing with a trusted brand used in over 260 million homes. - Advanced Modem Tech: Uses DOCSIS 3.1 for faster speeds, better security, and smoother gaming. - Strong Wi-Fi 6 Coverage: Dual-band Wi-Fi 6 delivers faster, wider wireless performance for your whole home. - Service Compatibility: Works with major ISPs like Xfinity, Spectrum, and Cox - Save on Fees: Own your modem and avoid up to $168/year in rental charges (varies by provider) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07M9J3XW2 | | Antenna Location | Business, Gaming, Home | | Antenna Type | Internal | | Best Sellers Rank | #283 in Computers & Accessories ( See Top 100 in Computers & Accessories ) #2 in Modem Router Combos | | Brand | ARRIS | | Built-In Media | 2-year warranty card., Cable Modem, Power Supply, Quick-Start guide | | Color | Black | | Compatible Devices | Personal Computer, Smart Television, Smartphone | | Connectivity Protocol | Ethernet, Wi-Fi | | Connectivity Technology | Ethernet | | Control Method | App | | Coverage | Wi-Fi Coverage : Up to 2,800 sq ft | | Customer Reviews | 4.1 out of 5 stars 5,070 Reviews | | Data Transfer Rate | 2350 Megabits Per Second | | Frequency | 5 GHz | | Frequency Band Class | Dual-Band | | Global Trade Identification Number | 00612572215432, 06125722154320 | | Has Internet Connectivity | Yes | | Is Modem Compatible | Yes | | Item Dimensions L x W x H | 8"L x 2.87"W x 9.33"H | | Item Type Name | Cable Modem & Wi-Fi Router | | Item Weight | 2.8 Pounds | | LAN Port Bandwidth | 1000 Mbps | | Manufacturer | CommScope | | Maximum Upstream Data Transfer Rate | 1000 Megabits Per Second | | Mfr Part Number | SBG8300 | | Model Name | SURFboard SBG8300 DOCSIS 3.1 | | Model Number | SBG8300 | | Number of Ports | 4 | | Operating System | Linux | | Other Special Features of the Product | LED Indicator, Parental Control | | Router Network Type | hybrid | | Security Protocol | WPA2-PSK | | Special Feature | LED Indicator, Parental Control | | UPC | 612572215432 | | Unit Count | 1.0 Count | | Voltage | 120 Volts (AC) | | Warranty Description | 2 years | | Wireless Communication Standard | 802.11ac | | Wireless Compability | 802.11ac | ## Product Details - **Brand:** ARRIS - **Color:** Black - **Compatible Devices:** Personal Computer, Smart Television, Smartphone - **Connectivity Technology:** Ethernet - **Frequency Band Class:** Dual-Band - **Included Components:** 2-year warranty card., Cable Modem, Power Supply, Quick-Start guide - **Model Name:** SURFboard SBG8300 DOCSIS 3.1 - **Recommended Uses For Product:** Business, Gaming, Home - **Special Feature:** LED Indicator, Parental Control - **Wireless Communication Standard:** 802.11ac ## Images ![SURFboard SB8300 - Image 1](https://m.media-amazon.com/images/I/61LnBKAPVAL.jpg) ![SURFboard SB8300 - Image 2](https://m.media-amazon.com/images/I/516T5Exo6rL.jpg) ![SURFboard SB8300 - Image 3](https://m.media-amazon.com/images/I/61s+gjkvbtL.jpg) ![SURFboard SB8300 - Image 4](https://m.media-amazon.com/images/I/51Lm62sIRmL.jpg) ![SURFboard SB8300 - Image 5](https://m.media-amazon.com/images/I/71dcyWSKYjL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: Does this router allow for remote managment?** A: Yes but actually no.

Now, after I had WiFi issues and unplugged and plugged it back in, the lights are green which is apparently the correct color. Oh well. So far it works. ### ⭐⭐⭐⭐ The best of the best Docsis 3.1 *by K***N on May 10, 2026* OK, with everything being working from home these days, online shopping and bill paying, researching, news, TV, and so on, I had a real need for speed and although my ARRIS Docsis did the job at almost 100 Mbps, it was not cutting it with seven high speed computers on routers and switches and one coaxial cable at high speed from COX. I signed up for high speed at COX but was not getting it. The issue was Docsis 3.0, cannot handle the new standards. So I did all my research from high prices to renewed, and found that the new guy on the block that seems to make only a few products, mainly the Hitron CODA56 Multi-Gigabit DOCSIS 3.1 Modem | 2.5 Gbps Max modem, seemed worth looking into. It wasn't the highest price, so I was suspect a little, but do not go by price alone. So I do reviews. The reviews were outstanding. A few reviews were a little down but I now know why. This is why I think some are having problems, not with this one, but all others as well: When you are upgrading speed, the latest standards are just not important, it is vital. If you keep the older Linksys SE1500 switches and router that runs at the 10/100 speeds, which were wicked fast for the times, you will stay at that speed. So, here's my biggest tip. Make sure all your older switches connect your scanners, printers, and peripherals that do not need that much, no need to discard the switches and buy all new GB switches and routers, just use it for peripherals. Also, with APC power containers in event of power failures, any switch lines going into it need to be taken out unless you have the newest models because, as I found out the hard way, it will limit you to the older standard. You can still use the APC without the lines or buy a new APC. Now, if I haven't scared you, it is really dead simple. Take the time to get the information, most of it is given to you along with the MAC address on the label on the box itself and call your ISP, and as long as you have done all the connections to your modem, just needs to be switched on and a competent ISP person will walk you through. Ours is COX. I know this model favors Xfinity of Comcast fame, but this model works with the most major carriers I have ever seen. That being said, most all the reviews were for Xfinity. I found you also need to use a tool and make sure the cable from the ISP is securely screwed on. Well, mine is a COX ISP, so all those that would like to know, COX is the catch up company still growing like lightning all over the country and for good reasons. They do mostly direct connects. Not all this wireless 5G do anything is all that reliable I believe. Anyway, I like direct hookup to cables for reliability. You hear all about wi-fi drilling a hole in your head. I believe it. So, I use routers and connect a TP-Link with an on/off switch, not expensive, and can connect a wireless for when I need it, even a travel wireless by ethernet or USB, but I can put it off to give my home a peaceful feel without wireless running except for when needed for laptops and kids. Shut the wireless off, shut the kids off, lol. When the router is GB and switches are GB and modem is GB, you have it made. It is as simple as that. Now it would have taken me about 30 minutes with COX to upgrade but I made all these mistakes I just mentioned here. I mentioned it in the hopes you will not make the same mistakes I made. Even with my mistakes you can learn from, it took me about 3 hours to get seven computers running. As a side note, don't fret your printers, drivers, windows, or setup. It is just upgrading your speed. You can always put your old modem back if you have to but I see it as the worse thing that can happen, or most likely, is your speed doesn't change. In that case, you will have your new modem running but using the older speed. Don't panic. There is some switches or routers that are older causing the speed not to increase. For all the new first timer setups, no problem, you will have all the newest stuff. This is just tips for us older timers, lol. Also, check your plan with your ISP. It may not be the higher plan. This is the best router I have ever seen that in this online world and it should not mean a technician will have to come to your home and pay $75 an hour or more. Buy this modem. It will pay for itself in less than a year without having to rent it from your ISP monthly charge. It works, it is brand new, and not refurbished with some renewed ones from Amazon even cost more on some of the more famous models. Always look at the number sold in a month, how RECENT the reviews are, and the product itself how many ISP's they support. I am sometimes in CT and live in RI and if I move, this modem handles so many different ISP's, that it can go with me and even for remote, I will never need 2.5 GB speed when I was getting along with just 100 Mbps. Now 1 GB modem speed is all I will ever need but nice to know if I need to download or upload a huge amount of data that I can up my speed with COX to 2.5 GB. Just like the old axiom, you are as strong as the weakest link, so remember with online website and cloud stuff, you are only as fast as the server you are on when in the cloud and, of course, assuming you have a decent speed computer. I highly recommend the Hitron CODA56 Multi-Gigabit DOCSIS 3.1 Modem | 2.5 Gbps Max modem. I took the time to write this because this Hitron company is running a huge discount right now, I think 43% at this time I bought it, cheaper than most. So, for cheap, I wasn't sure I should buy it, the you get what you pay for. In this case, this is a quality item and better than the pricier ones I believe, else I would not right this review. Mostly, it is so a few of you reading this not to make my mistakes. Upgrade your routers and switches, all should run at GB speeds first. Then call your ISP and connect your MAC address. In fact, they give you the number to call and it is the only one for any price I could see that claims it can handle 2.5 GB speed for the price. Hey, it's Amazon, don't work, can send it back. I ordered this modem last night, got it today around noon time and on a Saturday! Can't beat Amazon! Hope this helps anyone thinking of buying this model, 5 stars in my book. ## Frequently Bought Together - ARRIS (SBG8300) - Cable Modem Router Combo - Fast DOCSIS 3.1 Gigabit & AC2350 WiFi ,Comcast Xfinity, Cox, Spectrum & more, 1 Gbps Max Internet Speeds , 4 OFDM Channels - G-PLUG 10FT RG6 Coaxial Cable Connectors Set – High-Speed Internet, Broadband and Digital TV Aerial, Satellite Cable Extension – Weather-Sealed Double Rubber O-Ring and Compression Connectors White - RELIAGINT 30ft TV Cable Wire Black RG6 Coaxial Cable with F Connector, F81 Female Extension Adapter, Low Loss High-Speed Coax Cable Cord Extender for HD TV, Dish, Satellite, Antenna, TV Cable 30' --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/144037075-surfboard-sb8300](https://www.desertcart.co.uk/products/144037075-surfboard-sb8300) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-28*
