Customer Ratings & Reviews

Randomly disconnects. Which is terrible for working from home. Never had this problem with our old router but the isp forced us to upgrade. Not happy.

Dont buy it, wifi does not stay up, it always lags and disconnects devices

For a $300+ router it barely spans across my 2 bedroom apartment. Good signal in the room it’s in but other than that be prepared to drop to under 7 MBPS download speed

Bought for xfinity 1GB service as it was listed as supported. Wifi left dropping and xfinity told me to call manufacturer. I'm trying something else.

Is not what I waiting and I can’t return because my kids break the box

Not recommend it, Signal is horrible, connection is not good either after the cable kick off they won’t connect back.

This is a great product, but unfortunately it didn’t work for me.

Router kept losing connection numerous times a day

No, I don’t really want to review this item. Thanks

Why I do the internet speed test on my computer, it’s only give me 90 mbps WiFi g5 is 400mbps. My Xfinity plan was up to 600mbps. Is Bad modem/router?

Bad modem/router. Needs restart every 1-3hrs, connection lost, kick itself off ISP, high packet loss on pc. I dont recommend this.

UNBOXING AND INITIAL IMPRESSIONS: Packaging is simple, and straight-forward. The box contains the gateway, power adapter, and (yellow) Ethernet cable, along with a simple-to-follow instruction booklet. All packaging was cardboard, thus very environmentally-friendly. Not much else I can say…but nothing else really needs to be said. SETUP: Setup couldn’t have been easier. I disconnected my dad’s current gateway, cable-by-cable, leaving the power cord as the second-to-last, and the coax cable last. Next, I connected the coax cable to the new gateway, followed by the power, and then the Ethernet cables (for the printers). Unfortunately, I didn’t realize there was no RJ-45 jack until after the gateway was already powering up (more on this, below). Unlike my first Arris modem (my current setup contains my second), which required two phone calls to Comcast, the SBG8300 connected automatically. I thought everything was going great…until the aforementioned missing RJ-45 jack was realized. My parents use Comcast’s “Voice Service”, which is similar to VoIP, but with some slight differences…the biggest of which is that all landlines need to be connected to the modem’s/gateway’s RJ-45 jack. No RJ-45 jack means no Comcast landline service. OPERATION: To be completely honest, I really didn’t get much testing in. The modem & router functionality works exactly (as far as I was able to determine) as Arris claims, but I didn’t have it connected long enough to perform my usual distance/speed tests. THE GOOD: • Everything works as claimed by Arris • Automatically connected to Comcast THE BAD: • Nothing I am aware of (primarily due to not being able to completely test the gateway) THE UGLY: • If you are a Comcast (aka Xfinity) Voice Service subscriber, you will NOT be able to use this gateway FINAL VERDICT: First, if you are a Comcast Voice subscriber, and want to use an Arris modem, or gateway, you need to understand that these are the ONLY Arris models you can use: Gateway (modem/router) – SVG2482AC, TG862R, TG862G Modem – SBV2402, SBV3202, TM822R, TM822G, TM722G I am NOT mentioning these other Arris models to deter you from purchasing the SBG8300. Quite the opposite. If you don’t subscribe to Comcast’s/Xfinity’s Voice Service, then the SBG8300 will be an excellent choice, and I HIGHLY recommend it.

Nevertheless, the above review, be it positive, negative, or anywhere in-between, is a 100% honest review, and the price paid played absolutely no part in my review.

After a while can't login. Let me login on wifi but NOT on app. Showing wrong email or password. Please fix it.

Very bad very bad very bad very bad very bad losing connection all the time

I purchased to replace xfinity equipment but i returned did not work well i went with netgear

Nit getting the speed that was expected from this device

WILL MAKE YOU INSANE WITH ISSUES CONNECTING AND DROPPING! COMPLETE GARBAGE!

not working after couple of months, support app everything is garbage. Don't buy

Now that this modem and router is installed I am very happy with it! The connectivity has been much better than my previous mesh network, which would lose connectivity for the devices connecting to the mesh points. With that said, I am rating this as 4 out of 5 stars because of the trouble with installation and because of the poor quality of the app. I am hoping the app gets better with some software updates. The app could not connect to the modem/router the first dozen or so times I tried. When it finally did, it made it a few more steps before crashing. Then I had to start over again a few more times. When I finally got connected and created a new account, the app was still unable to login in most cases. I also tried logging into the app when away from home and it doesn't look like it has the capability to do so. Other than the trouble with the app, the modem/router has worked great! We have a 4,000 square foot house with three levels and this is installed in one corner of the basement. The signal is strong and can reach up 2 floors and to the opposite side of the house - prior to this I needed a mesh network to achieve this. Also, the speed is amazing. I have Spectrum service and this can get download speeds of over 210 Mb/s on WiFi. The upload was only 5Mb/s, which seemed a little slower than my previous connection but it could be caused by other issues (time of day, other use in the house, etc). Overall, very pleased with the results and looking forward to better connections!

I did not even purchase this product so totally confused as to why I am being asked to review?
