Customer Ratings & Reviews

I bought this cable modem after upgrading from 200Mbps to 400Mbps service. With the old modem I was renting from Optimum I barely cleared 200 and they confirmed that I needed a newer one for the higher speeds. They sent me a new one overnight at no cost, but I had been wanting to buy my own anyway to avoid the modem rental fee. Assuming no premature failure, I'll break even after just over 1 yr since rental was $10/month. No regrets. The manual setup to enable the new modem on the Optimum network and connect it to my account was fairly painless. I did have to upgrade my router as well because it was another bottleneck, limiting me to just over 300Mbps even with the new modem. But with the new router and new modem in place, I get around 420Mbps download speeds as advertised and the connection has been stable for over a month. Optimum makes it difficult to be confident that a cable modem you buy will work on their service. They list only 3 or 4 compatible modems on their website and all were Arris Touchstone models that seem not commonly sold direct to consumers. I only found refurb models for sale of the higher end one that I needed. Most Arris SurfBoard, Netgear, etc cable modems print on the packaging which providers they are compatible with, but I found zero online or in store that officially state they work with Optimum. I'm sure Optimum would rather you pay to rent them anyway. The Best Buy rep in store was aware of 2 others that work with Optimum, but even they didn't know that this one also does.

Easily installed with my ISP. Fast speeds, rock solid connectivity. It feels very warm to the touch, but so far it has performed flawlessly since installation.

My intent was to replace the tower provided by my internet supplier (starts with an "X") so I didn't have to pay for it every month. I learned that I needed both a router and a modem in order to do so. (May be common knowledge...) so I needed to purchase two separate units. Will take me roughly 2 years to come out ahead on costs, but this Arris modem is built for what's coming and should last well past that. Set-up on these types of items has become very simple: scanning a QR code, downloading an app and standing aside to let it configure itself. Over the last month it has performed as expected and I'm pleased with the purchase. App interface is simple and intuitive. Good purchase.

Priced right easy set up quick connecting . Great purchase for the cost

I purchased this to replace another Arris SURFboard modem. The replacement was not due to the previous version breaking but purchased faster internet. This unfortunately was sold out and I had to purchase a Netgear version first. I could not return the Netgear fast enough. Arris is far superior in speed, reliability, and price. I'll never get another brand of modem. Also, the old one made its way over to my parents and still ticking strong.

Works great!! My other modem was failing and would not stay connected. This was easy to set up and has worked like a charm.

I bought this modem last night to use with my spectrum 400mbps internet. I am writing this review to let those who like me are wondering if it works with spectrum. Yes, it does works but it does not configures itself with the spectrum network automatically. you must call customer service to have it activated. The modem has two network ports, and each port needs a separate IP address per Arris customer service. Spectrum only provided one IP address, so I will have to call ask for a second IP address if want to use the second port. After installation I upgraded my internet to 1 gig, and now I have a super fast internet connection and this modem is working great. I also had to reset my router because it had the old IP address registered and it was only pouring out 400mbps after I upgraded my internet. My existing router is a Linksys MR900 and it work good wit the Arris SB200.

Take in count this is DOCSIS 3.1, you will need this only if you have a gigabit plan, for lower download speeds a DOCSIS 3.0 will suffice If you have a plan lower than 1Gbps this won’t give you faster download speeds. Check with your provider before buying Also, this has 2 Ethernet connections, if you want wifi you will need to buy a separate router Pros: Save on modem rental fees Easy to set up (just call your internet provider and give the MAC address clearly printed in the unit) Good quality Performs as intended Cons: None so far

Been using several Arris modems for years, they are of great quality, though would be great have they are build of better plastic and have black color too. If you have Gigabit speed internet, SB8200 or and modem with DOCSIS 3.1 is a must, otherwise, your ISP may not like it and you may not get the speed worth. This modem squeeze out as much as it can from my ISP and speed is great even during high traffic hours. Make sure to check with your ISP that the modem is compatible with your Gigabit speed. If you have anything else lower, this modem is unnecessary overkill unless you want a future proof product.

I purchased this new Ahis Arris Surfboard 8200 modem to replace the identical model which was over 5 years old but was starting to lose signal and drop the connection to my Cox Gigblast service. I decided to purchase the identical model to replace the original modem which had served my family and I faithfully for over five years. Even with the occasional drop of signal the original modem was still running strong and giving my home the speeds I'm paying for from Cox. Additionally this is a recommended model from Cox (according to their tech specs) so I decided to be consistent. Best Buy was also kind enough to take 20% off the purchase price when I recycled the old modem. So save money in the long term and don't rent from your ISP. Buy this modem and save those monthly fees. On a side note, once I set up the new/replacement modem with Cox, all I had to do was swap wires and bring my home built wireless network back online too. Go get yours today!

I like it because I don't have to pay the cable co. For a modem.. It has a great velocity. No problems with it. It was easy to connect. It gives me fast internet connection.

If you have or are getting high speed Internet through your cable company soon, this is the modem offering future-proof performance for a few years, By high-speed, I mean 400mbps up to 1GB of speed, this modem is the best of which I am aware. To be clear, I am not aware of ANY cable Internet providers that have activated all the capabilities built into this next-gen DOCSIS 3.1 modem. If you own your modem, then it is your cable company that runs it and has control of it, as far as internal firmware and settings are concerned. Owning it means you have the opportunity to have a better piece of hardware than what any cable company will provide. Remember that THIS is a modem ONLY, not a combo device with built-in wireless (Wi-Fi). That is an additional piece of hardware. If you are not using a lot of bandwidth and have no idea what this is, you probably do not want, and certainly do not need this modem. I love the performance and traditional reliability of this brand, not that others are not as good or nearly as good. I've had good success with the brand.

Simple installation, very fast throughput speeds on 600mbps Xfinity service. Auto-switching 3.0 and 3.1 depending on equipment attached and speeds available. Very happy with purchase. The only issue encountered during installation was not related to this modem. The previous owners did not cancel their internet service, so Xfinity had to cancel, adding a day for forced cancellation to upload. Once my internet service was available at the house, install was very quick and easy. Highly recommended.

Compatible with Xfinity cable...good speeds through modem. Reviews said it gets very warm...I agree. Placed modem in cool room with a fan pushing air through the case. It's just a plain modem without any router functions. Design flaw by Arris / comscope... should have a fan installed from factory

Compact and works great for my space. Initially seemed to struggle to provide up to 600 mbps but after a reset it works perfectly.

work size and tenant no complications so far on got last 1 poped out

It took a bit of time to get setup. The setup procedure that came with modem did not work for my provider. Once I contacted my provider and get setup. the modem work fine. I was finally able to get the speed I was paying for.

I've purchased this modem and the netgear cm1000. I fully tested them both in all things important. The arris came out on top in my book. The arris sb6190 was a train wreck of a modem and put a dent in the arris reputation, but don't let that hinder you. Netgear had the cm700 too. Puma 6 was a fail. Still no fix. Arris was even able to acquire a lawsuit over this. Anyway the sb8200 was originally thought to contain a puma 7 chipset. Neither the cm1000 or the sb8200 thankfully gone down that road. We're back on Broadcom with a bcm3390. This thing is solid. During tests I've recorded 2ms decrease in ping vs the netgear cm1000. I also almost instantly bang off the max bandwidth rev limiter. The netgear is just as fast but took a second or so longer to reach full bandwidth. I am subscribed to 300Mbps. I am hitting 362 max but usually sit 359-360 consistent speedtest. Netgear sits 358 with occasional spike 360. Both held 30Mb uploads no problem. Out of the 32 channels I am currently only linked 24 in my area. Both modems chose docsis 3.0 in the download. Chicagoland/gurnee. Hopefully we see 3.1 rollout soon. According to the front panel on the arris it indicates a 3.1 link on upload but modem page says otherwise. 4 uplink channels. On docsis 3.1 peregrine firmware. You can't go wrong with either one of these. But if you want the edge and a possibility of link aggregation. Spend the extra $10.

Needed to do an upgrade on my modem. Went from a docsis 3.0 to 3.1. Internet connectivity seems to improved. The new SB8200 is a good purchase. Price was reasonable and performs fine.

So far works great. Replaced a Motorola that was more expensive 2-3 years ago. Activated with Xfinity with a couple restarts. We get around 850 - 950 mbs on a 1.2 gb plan which is plenty. Easy set up and we'll see about long term reliability.
