    • Not Reliable - DON'T BUY (or SB8200 model) - Unless willing to keep cycling every few days or less
Review Image by Luis Amaral

Review Image by Luis Amaral
First of all let me say I am a Systems Engineer with good experience on this subject. And from my perspective and tests I've done so far, I can tell this is not a reliable product. At the begging I had a good experience with the Support, good people very respectful that look to care about your problem will answer you in a reazonable way. But after few interactions, tests, and changing my modem twice for the same model (SB8200) and finally to this model (SBG8300), they pointed me to the signals out of range, after looking at the modem QAM table on the GUI interface. Then asked me to contact Comcast to solve this problem (signals outside standard parameters). I've contacted Comcast and they openned a ticket to change all the connectors and cables (including cables burried under ground on the street) for my installation, and after some adjusts on the their equipment all the signals were with the specs requested. After a week then, boom... Again the modem freeze (no access to GUI anymore), and it starts to lose packages on the network at a rate of 80~90% Loss. On my home I have a cabled network that are connected to a pair of Gateways (pfsense active + backup) and both gateways are connected to two different internet providers (Comcast and XFinity). I have ordered Comcast XFinity Gigabit a few months ago, and have tried three different modems from ARRIS on this setup, and all of then showed the same behavior. After few days start loosing network packages, what lead to internet speed degradation until it is practically useless. I then give it some time to test this modem for a while until now, but it keeps doing the same thing over and over and sometimes I have to restart it twice until it gets a good connection for a few days (5 to 8 days) and then I need to restart it again. I've beeing think about some workaround, but the modem/router doesn't have a feature to schedule an auto reboot, and yet there are some times you have to reboot (hard restart) it twice to get a good connection. So, probably useless to try to use an smart outlet to recycle power on a scheduled time neither. If it didn't connect well after the first recycle it will be useless, so again, not reliable. I Never used the embedded WIFI from this modem/router as I just need cabled internet to my routers/firewall. Nothing to add about WIFI quality or usability. Summary of Problem =================== Modem start to loss network packages after few days running, what is clearly log on my gateway and firewall (pfsense). When this is happening, you cannot access modems GUI as modem doesn't respond to the GUI requests. It is probably a software issue on the modem, but I didn't try to break into the modem to investigate it. Anyway, as it start works fine after a hard restart (sometimes twice), it is mostly likelly to be a software bug or design flaw, and the "restart twice" thing might be related to a persistent cache of some sort that only get flushed after the second restart. Conclusion =========== After using the modem/router for a while (ARRIS SBG8300) and after trying different ARRIS modems (SB8200) since Nov 2019. I believe this series of Gigabit modem have an Important reliability issue on the firmware (software) that doesn't implement adequate quality assurance mechanism for the connection and are incapable of self recovering from a degraded connection situation making it a BAD option for most of users as it is NOT RELIABLE and need to be RESTARTED frequently to make sure it is running a health internet connection. UNLESS you are going to reset or restart this modem daily or don't care to need to restart the modem (sometimes twice), everytime your internet is SLOW, that is not a product I would recommend at all. Neither this or the other modem (SB8200) that also had the same behavior. * I tried not to be too technical on my review, beside the short description of my setup, but this is my first extended review that I feel compelled to write. If you need any details feel free to reach out by leaving a comment. I don't think I can share my email here. ** ARRIS told me over the phone they cannot update firmware, but only ISP (Comcast) would be able to update it. But again, that is not the sort of answer you want to hear from a product with that price Range.

    • DO NOT PURCHASE THIS PRODUCT IF YOU PLAN ON CUTTING CABLE!
This device does not support wifi streaming. I conducted 2 speed tests with this device: 1. WIRED - via Ethernet directly to the modem, my download speed was 286 mbs (I pay for 250 mbs) 2. WIRELESSLY - TWO FEET AWAY from the same modem my download speed dropped to 80 mbs!!! I returned it to Amazon today and replaced it with a Motorola MB8600 modem and an Eero mesh network and my wireless connectivity = 255 mbs! ... show more

    • ARRIS Surfboard/SBG8300 Docsis 3.1 Cable Modem Plus Wi-Fi Router
I've been using an ARRIS docsis 3.0 modem/wi-fi combo for the past 5 years and I thought it's about time to upgrade to docsis 3.1. I'm glad about my decision and purchase considering the price and supposed to be top of the line model, SBG8300. Because I saw the difference with regards to speed (I'm using Xfinity at 275 Mbps plan), which increased to 390 Mpbs! Thank goodness that it's been pretty consistent after almost a month of using it. Plus, you'll get an extended 2-year warranty after you registered the product on their ARRIS consumer support website. I hope that you will also enjoy having it as much as I do. It's highly recommended, delivery is guaranteed free and fast straight from Amazon. ARRIS for me is a trusted brand, so go ahead and buy one! ... show more

    • If you've owned Arris before, own it again. If you haven't own it now.
Let me start by saying I'm writing this review in this level of detail as a professional in the Engineering Technology field and while my opinion is biased, I hope my feedback will help provide a better decision-making experience for any person trying to work through a crowed field of products. I was not paid for this review. I've owned Arris Modem/Routers for years (I dont remember exact span, but it's been a while.) - The last one I had was a very good router, it had just become a little faulty this last year and had started to show how it was falling behind on the technology side of things. Before I bought this one, I figured I'd try a different brand to see if I've been missing out on any other interesting things in the technology universe. I tried out the Netgear Nighthawk to much disappointment. Arris offers a lot of customization in the IP portal if you know what you're doing which really allows you a very good amount of control and allows you to maximize the product's effectiveness. The Netgear modem did not at all, amongst other issues, and I was not impressed whatsoever. So I went all in on Arris, and got the SBG83000, and so far I have not been disappointed. Having the customization back in the portal, ease of installation, stability and everything I expect from an Arris Modem/Router. I did read some complaints about wifi-speeds from this router before purchasing, so I decided to do a few tests when receiving this product; As a Manufacturing Technologist, I felt obligated to investigate* this issue a little upon receipt. *Granted, this does not mean that others do not experience issues as product quality can and will vary from customer to customer. Over the course of a week without resetting connection or power-resetting it I checked speed tests, and they consistently matched wired connection in terms of Upload/Download speeds, with a difference of 6ms in ping to servers on average. Provider: Comcast - Xfinity | Region: US - Detroit | Plan Speeds: 200mbps Download/10mbps Upload *All tests were performed during non-capped hours of operation as designated by the provider. **This is important as your provider will cap speeds to deal with high traffic hours based on your region. Total tests: 142 over 7 days. Download speeds to US Servers (All regions): 227 - 255 mbps range over 7 days, averaging 241.2 mbps. Upload speeds to US Servers (All regions): 10.1 - 11.4 mbps range over 7 days, averaging 10.85 mbps.
