Customer Ratings & Reviews

Unfortunately we returned the modem, because Spectrum required us to use theirs. We did buy a router at Best Buy that has been awesome.

Has been a good unit. No issues. Works as stated by manufacture.

Could not get the advertised speed from this modem even with fast service from Comcast. It was easy to hook up however. Returned it and bought more expensive unit.

This is a great modem. It's fast and very reliable.

Great router to use with xfinity. I had some issues with my previous router so this was what I chose to replace it. Great decision on my part.

Super fast. For now, it only stopped working for one time

Helps with streaming. Less buffering and fuzziness

this modem use only people that just use internet not over 1000 Mbps..

The set up process (Comcast). Could not have been easier. I activated online and my home network was up and running within 30 minutes. Looking forward to using this modem, I hope, for quite some time.

I've used Arris modems, and their Motorola predecessors for 10 years now, so when I needed a new one, I didn't hesitate to select another Arris. The store rep suggested the lower-priced model for my 75MB Comcast access; I should have listened to him. I decided to buy up one step to the SB-6190, perhaps to "future-proof" my investment a bit. A couple of months later, I've replaced it with a TP-Link TC7650. It turns out that the SB-6190 has the Intel PUMA 6 chipset, which has a known issue of slowing down Internet speed, requiring reboots at least once a day to "refresh" the device (which is essentially a small computer). My SB-6190 has the latest firmware update, which supposedly fixes the issue, but it didn't. If someone subscribes to lower speeds, the problem wouldn't occur, or they'd never notice it, but the whole point of the SB-6190 is all the extra channels for optimizing higher speeds, so if it can't reliably support higher speeds, it's useless to me. Other Arris models are fine; none uses the PUMA 6 except SB-6190. Avoid it! Or look at Zoom, TP-Link, maybe Netgear. Look for a Broadcom chipset. The TP-Link is really nice, and doesn't have the glaringly large, bright LEDs of the Arris, so it's less obtrusive anyway. I requested that Comcast remove the SB-6190 from their list of supported modems; the tech I spoke to agreed and said he personally has the same unit and the same issues, and that they receive many customer calls to troubleshoot this issue, which is basically unfixable. You've been warned...

I bought this for the speed and to future proof. Though time warner says it is on their approved list, I think it was recently added and they didn't even know how to really activate it.

5 years ago I would rate the SB6190 5 stars but today if your on COX cable they won't let you have an upload speed faster than 10mbps even though the modem rating from the MFG states 262mbps upload.

This works perfectly with my comcast service. The streaming movies are fast and excellent quality.

I bought this modem after reading the reviews. I recently upgraded to Cox's fastest advertised speed, their Ultimate package. This router was supposed to work well, but I have since discovered that there are excessive amounts of packet loss and uncorrectables. I now receive errors just testing the speeds via speedtest.net. I will be returning this for something different.

With local internet providers delivering gigabit speeds, you've gotta allow the bandwidth in and this router does the trick.

It's fine the only troubel i have wih it was it was from the internet company

Have no interest in paying to rent a modem when one can be purchased which is faster and will pay for itself over time.

I would highly suggest this for the price and quality and why not stop paying the internet provider fees.

The box lists a lot of cable providers and states it is capable of 1.4 Gbps download speeds. This is true, but it depends on your ISP. Xfinity requires DOCSIS 3.1 for speeds Gbps speed tiers. This modem peaks out at 500 Mbps. This is fine for most people, but this device may not be right for you if your ISP limits speeds for DOCSIS 3.0 devices.

I have used five modems in the last 23 years. The SB6190 is the worst of them all. It generally performed well, some latency issues but totally quit after just seven months. No LED'S, no power and it wasn't the power supply. Arris will send a replacement but they were not very efficient or cooperative. It took three calls to arrange a return because of incompetence. I had to buy another modem because I couldn't have to down time. I bought a Netgear modem and will use the replacement Arris as a spare if ever needed. My advice, don't buy this modem. The Intel chipset inside has a bad reputation for early failures.
