Customer Ratings & Reviews

Switched to Xfinity/Comcast cable internet. Made sense to buy my own modem rather than pay equipment rental fee every month. This modem is the most economical option. No problems setting it up and has been working so far.

I would have to say that my feelings regarding this modem was a small roller coaster ride, but after using it for a while this is my take on it: it does its job. When I first started using it, it was a straight work horse. The speed was handled and for a while, no complaints. Then the fluctuations in speed started. As I couldn't figure out the problem, I tried calling the ISP which ran speed tests. On their end (their opinion) it worked fine and stated that the modem was doing its job, for what the statements were worth. After researching the modem, I called the manufacturer and they also ran some tests. They stated that the ISP was not offering exactly what the modem was built to handle, as if I had the previous modem of before. I went bacj to the ISP and they worked their "magic" to the best of their ability. The modem performed slightly better, even after reading reviews of this modem that were not as favorable. My conclusion: the modem is worth its weight. The ISP is not always stable and will dip and change, depending on your hardware, your ISP hardware, other people's hardware, their usage and the network health. Do not let the negative reviews stop you from buying or considering this model, regardless of the factors listed, has not failed me since integrating it into the network. P.S. : if it gets a little heated, that's be abuse of the design coupled with extended high usage due to multiple 4K streaming.

After using the older model For 7 years straight that can only handle up to 300mbps, it’s had a constant on/off defect. After purchasing this unit - I’ve only encountered that issue less than a handful of times but it was mainly due to my ISP. Future proofing my household as the general speeds increase overtime - this sucker can handle those fast speeds. Def. Recommend for general home use. Plug and play after activating it through the ISP.

This is a good modem. It works fine most of the time (occasionally I have shut it down to reset it due to internet slowing down). But, I can't say it is the modem's fault. It is probably the signal from the Internet provider. It is pretty fast when everything works great (the modem itself works fine). I have an Apple router and a network extender. I cannot recommend this combination, because of various issues I experienced with the network. But, I feel good about recommending this modem.

Docsis 3.0 upgrade that is faster than my older one. does not heat up. Easy set up

Great modem. Works great with Spectrum. Was an easy setup and activation. Tests much faster than the rental.

This was a great upgrade from our previous cable modem. We really like that this only a modem and not also a router. We paired it with the Netgear NightHawk and have excellent wifi and wired connections throughout our home. The modem holds up to our speeds of 300 mbps well and was super easy to set up. We felt that for the price it was an excellent choice for our needs. I would highly recommend.

Easy to setup and delivers on speed as well. Never an issue with connectivity

Got this to replace my old modem which suddenly died. No problems with installation and activation on Spectrum and it's been running fine for the past week. The only thing that bothers me is that the status lights are a little too bright for where I had to place the modem. It was like a blue night light. Taped a grey piece of paper to the front panel to dim it a bit while still allowing the lights to be seen. Other than that, no complaints.

I was running a SB6120 for years and just recently upgraded to the SB6190 (simply for a speed boost). Fortunately the upgrade was quick and easy (very unlike Comcast) and the performance difference is noticeable. I've installed this modem for a small business (20 user office) as well as two residences and this modem works perfectly for each case. The price recently went down for this model so if you're in the market for a new broadband modem that works well, then look no further.

Easy setup and works like a champion. Good up & download speeds. Works on Spectrum. Will pay for itself in 10 months.

I switched from broadband to cable internet. To avoid the monthly equipment rental fee, I purchased this modem and a Norton Core wifi router (after reading many reviews), and I'm thrilled with both. I purchased a 150 Mbps internet plan and I'm getting 176 Mbps download and 25 Mbps upload via wifi! I think the modem is helping, because it will handle up to 1.5 gbps. It also has never failed, nor have I had to reset it. Highly recommended and a good value for the price.

This cable modem works great. Easy to install, keeps on running reliable and is fast for downloads.

This modem was a perfect replacement for my old Arris modem that I had for over 5 years (I'm keeping it for possible backup as there was nothing wrong with it), prompted by Xfinity alerting me to make the change to enable their faster internet speeds without issue. It started up and after a quick reset, was up and running ever since.

So I went into best buy needing a modem, and this is the one the associate suggested. I was skeptical at first; I'd always been a netgear user, but the associate assured me he was getting well over 100 mbps. Well I hooked it up to my orbi wireless router, and got 117. Far better than I anticipated... thank you for the help! Not only did it surpass my (admittedly low) expectations, but it was relatively inexpensive, given all the alternatives they sell.

I went to Best Buy to buy a router since ours was old and we had added so many WIFI enabled gadgets that we kept dropping the signal. On the advice of the salesperson I talked to, we also replace the TWC/Spectrum modem with this Arris modem. What a difference!! We used to have to unplug and refresh the old modem once every couple of days because everything would slow down. We've had this Arris for a couple months and haven't had to reboot/refresh it yet!

Works flawless! Speed is stable and faster compared to previous modem. Other brand owned previously did not hold up as long and speed constantly drops. Had to restart modem each time to have speed back to where it should be. Arris is my go to!

impossible to set up alone ( i tried the app and through the automated troubleshooting from my ISP). the indicator lights are overly bright. overall, it works well, giving me over 500mb download speeds with Cox (my plan is 500mbps). its compact and reliable so far

Had it for about half a year now. Works well with our Xfinity internet. Works fine and internet speed hasn't been an issue. The only real complaint is that occasionally the modem will just turn off and then come right back on. Lose internet for about a minute as it cycles through the light icons. Don't know if this is a problem on my end or with the unit itself. Has only happened a few times in the 6 months I've had it, but it does make me wonder if it's going to get worse. Also, its very bright!

Has a good price easy to set up great speeds customer service was excellent in helping me choosing the right modem
