ARRIS Surfboard SB6190 32x8 DOCSIS 3.0 Cable Modem with 1.4 Gbps Download and 262 Upload Speeds, White (Non-Retail Packaging) (Renewed)

This modem was known for having a widespread hardware problem in the intel chipset causing latency and lag, however I have experienced none of these issues nor dropped connections. The only time this unit drops connection is when the area goes down, never had a problem with the unit itself. It does run a little hot, but it has never overheated or caused any heat related issues. Perhaps they were able to fix the issue in a firmware update. (your ISP updates firmware for it when you connect it to their network, you can't on your end). If you don't care about faster internet and just want something basic, this unit will do just fine. But if you want gig plus speeds and something future proof, spend more.I have the 600mbps down plan from Xfinity and speedtests average about 650 down and 40 up. If they jack up the speed again I may have to upgrade but this still is great for plans under gig speed

Ours quit, this one works!

Using this for my Xfinity backup internet on my unifi equipment. Works fine with my 300mb plan. It's an older device though and those who want or need higher speeds at some point will need something more substantial. However for my backup internet needs, works great.

I would give it 5 stars but Comcast made it problematic. I purchased a $30 refurbished one on Amazon. It works as better than the Comcast OEM device, but you need your own modem too, which I already had a T-Link Google On hub. It should be plug and play, but I think Comcast makes it hard on purpose to get it up and running. Setting it up took 2 hours with Comcast having to debug their system. Comcast is terrible. But renting their modem for $15 a month is highway robbery. Don't get suckered into that. Buy your own. This Arris device works just fine provided you have a good modem to go along with it. It works faster than the Comcast equipment in my speed test.

i got this in Feb 2024, i’m not sure why but my internet is always going in & out. there hasn’t been a day in the last 6mo that i don’t experience terrible internet connection. I thought it was my internet service but they said it was the modem. before this one i had a motorola modem & i didn’t experience slow internet connection till 3years after & i replaced it with this one.

I got rid of the Xfinity modem, which Xfinity tried to charge me $15 per month for after the introductory term ended. I bought this one, connected it to the cable, and it works perfectly without any issues. Just be aware that if you are paying for higher internet speeds, this modem may not be sufficient.

xGiving wkEnd -20%off already low price, so bought two. 32 downstream links, so beyond Gig speed, if you might pay extra for that later. Like every I've hooked up, first time opening any website, provider offers activation ("Provisioning") and ready-to-go. Firmware fixes invisibility "come down the wire". Easy

I got this because according to the description it would work with my internet service. It is wrong. MAKE SURE TO CHECK WITH YOUR INTERNET PROVIDER BEFORE PURCHASING FOR COMPATIBILITY. I ended up sending it back for a refund.
