Still working after 6 years
I purchased this SB6183 black on Amazon in 2019 six years ago and it’s been flawless. Never a disconnect or reboot needed. My ISP is Spectrum with 400 Mbps download and 10 Mbps upload plan. The modem delivers that. Only reason I would replace it would be to get more speed as gigabit service becomes more common.

Nice Internet Modem to replace your cable company’s rental modem
Awesome cable modem that eliminates the monthly rental charges that cable companies live for. Capable of a download speeds up to 686MB. Has plenty of status lights on front to tell you what is happening at the moment. Can log into the unit to determine packet loss, errors and channel status.This is a simple modem that does its job well. If you are paying Comcast, WOW!, Xfinity, or another company a monthly fee then this is the unit for you. Simple to setup. Just screw the coax into the coax connector, plug in the LAN cable for your router, and plug in the power cord. Then call your cable company and tell them you bought your own modem. They will ask you for the MAC id number on the bottom of the modem and then they will authorize it to work with their network. That’s it and you are up and running.PROS:- Nice price- Super easy to setup- Saves you on monthly rental fees from your cable company- Can support download speeds up to 686MB- DOCSIS 3.0 for 16 Channels Down / 4 Channels UpCONS:- None

This ONE – x16 downstream; x8 Upstream. Dependable, affordable, and should last you ~14 years
Sometimes, you look at the Specs – and you think “it’s a Surfboard Modem, and the SB6190 boasts x32 downstream and x16 upstream – that has GOT TO BE BETTER”, and you drop $140 in my case, and then you kick yourself.Why? Because Intel released a buggy Puma chipset, and Arris (Motorola) released a crappy, over-priced, unstable modem – and has not gone to the trouble to either fix the Puma chipset, upgrade to a stable chipset, or even attempt a firmware fix.So, what’s wrong with the SB6190 and why do you want this one? After all, it’s about half the maximum bandwidth. The “upgraded” modem boasts that is made for gaming. Unreliable connections, >50ms – 150ms jitter is the LAST thing anyone who games, or even streams Netflix wants. Do you like movies that pause for no reason at all? How about streaming apps that randomly freeze for no apparent reason? How about having to reboot your entire network (which can take 10 minutes alone) …. just because?That’s why you want this SB6183. It’s capable of 650+ Mbps from Cox, Xfinity and others, it’s DOCSYS 3.0 compliant, it’s supported – it’s pretty much legendary for being reliable – and STABLE. What you want in a home network, is a freakin’ ROCK. You set it, and you forget it is there. It should last years – decades even. If the most typical home bandwidth today is 75 Mbps, and it was 25 Mbps just 5 years ago; then the next bump will be in the 200 Mbps range in ~7 years, and perhaps 600 Mbps in ~14 years. What else can you think of, that will likely be serving you just fine in ~14 years; besides a well built work truck?

small and functional for what I need
I’m not an avid reviewer however, since I read others’ reviews, I find it necessary to sometimes give one myself. I had an old Zoom modem that was great and lasted quite a long time. It started running a little hot so I thought it was best to purchase another one. Unfortunately, I was no longer able to find that same type. So, after a long, exhausting search into the pros and cons of each, I settled for this Arris Surfboard modem. I like that it is vertical instead of horizontal, small and takes up very little space. Nothing fancy but does the job. Very easy to install, works with Cox so my review is that I am very satisfied with my purchase.

Love Cable Cos That Let You Buy Own Modem
I love when cable companies let me buy my own modem, and stay away from subscribing if they force their equipment on me. I had the previous lower speed version for my studio apartment for 100mbps internet speed. But I moved to a larger house and installed Eero mesh system with 300 Mbps intent so I upgraded modem to this one. The tech gadget reviews said this has a much more stable connection than the faster Gigahertz modem so I opted for stability. I get the max download speed for 300 Mbps which is amazing since most users wouldn’t get what the internet company sends due to wiring or other issues. I love Arris products, reliable, high quality, durable, and easy to set up and trouble shoot. I always choose above Netgear, Cisco, Motorola, and Asus always dies on me after a year or two so won’t buy Asus anymore

Works Great
Works great for my 200/20 Mbps internet through Sparklight. I had an old Surfboard that finally started to fail and replaced it with this one and have had no issues at all. I set up the exact same one at my uncle’s house when he upgraded his internet, and he hasn’t had any trouble out of his either.One con that isn’t star-losing-worthy but it would be nice to have a fix for — this modem’s IP is 192.168.100.1 and there’s not a way to change that. I’d much prefer to have it at 192.168.0.1 and my router and computers on 192.168.1.x, but I suppose that’s just a personal preference. It did make finding the thing on my network a bit difficult, though, especially considering that when you hook into it, it connects you DIRECTLY to your ISP’s DHCP server. Then again, that saves on routing time and supports more configuration through more equipment, so again I suppose it’s all about personal preference.Regardless, it works and it can easily just be set up and forgotten about. Worthy of 5 stars.
