Customer Reviews for ARRIS SURFboard Gigabit+ DOCSIS 3.0 32 x 8 Cable Modem SB6190 in White

I decided that after a long time, an upgrade from my SB6120 was due. Was looking to increase my speed, or at least have gigibit ethernet on my router so that I could take advantage of higher speeds. Installation for me was painless. I have Comcast, it is a supported router for them, called up, provided MAC, and less than 15 minutes up and running. Read a couple of reviews after I got it and, while my paid for internet speed is only 100 megabits, a far cry from what the actual modem can do, I see no tangible difference, but I wasn't expecting a giant speed boost, just a little. For me it is stable, but I do notice that the jitter is a little higher. If you look at my screen shot, the left of the large spike is the old modem, the right, new modem

Infinity said that this modem is compatible with its service but never said that you need a router as well so the product is good but you have to buy an additional router

This was a replacement for the next model down that was ruined by a lightning strike. I decided to buy the next model in the SB lineup because mine was already 6 years old and I figured Arris might obsolete it or Charter Communications wouldn't support its use. Like all of Arris products, it was easy to unpack and install. Charter identified the new equipment and initialized it remotely. I was back up-and-running within 20 minutes.

My SB6190 performed well but had a short life. It failed after six months.

I bought this modem six years ago and it was very solid/stable. It did what it needed to. About a month or so ago I started getting random dropouts then it completely stopped working. Six years is a good run and I was planning to upgrade to a DOCSIS 3.1 modem anyways, so I opened it up and found out what the failure was. The modem generates a lot of heat (which discolors the plastic case, fyi) and the heat sink on the processor is held on by plastic clips. Over time the heat, apparently weakened the plastic to the point they snapped and the heat sink fell off (it's mounted sideways). My guess is that the lack of the heat sink is why the modem started dropping out and then eventually fried. This is just poor manufacturing on an otherwise good product. If they ahd used metal screws, instead of plastic clips... I'd still be using mine today.

We bought this product because we upgraded our internet service and our older Arris modem needed to be upgraded. The ordering was easy. The item arrived promptly. It was easy to set up and get running. It seems to be doing it’s job!

Installed this modem at our international denominational headquarters (11: work-stations, 2: emergency phone lines, 3: big-screen TV's and video security). We have had it installed for 2 years (powered through our UPS) and we have had to reboot the thing a grand total of 4 times. This beast is a rock-solid workhorse.

This is my 2nd SURFboard cable modem. The old one worked just fine except that in upgrading my internet speed, it was too much for the 8 year old modem. Since I was happy with the old modem, I didn't look at any other brands when purchasing a faster modem. Easy to set up and with a quick call to my internet provider, and it was up and running within a few short minutes. I am very happy with this cable modem!

Just installed two days ago. Can’t get the uplink light to come on?

Good one for a family home. Easy to install and maintain.

I just bought this modem and Xfinity could not add it to my account, they told me that something was wrong with it from the manufacturer and to return it and get a different modem. After reading reviews, seems to have a common issue related to a bad chip and a lawsuit concerning this. Wasted a lot of time trying to get it to work, very disappointed. The surfboard modems used to be the best.

This modem has been working flawlessly with Xfinity 300 speed service. You can log on to the modem and turn off the status lights if you want they are really bright.

Modem was pretty bad i've tried numerous ways to fix it. Put is this way i was first kid i knew with a 300 baud modem. I remember my 2400 baud was too fast for many sites. Ive been into computers along time, this one is not great with Xfinity, and i bought it because they advertised that it was.

I use this as a replacement for Cox. It's a great modem.

We've had this modem for a few months and it works great. Installation was a little difficult, but once I figured it out it was a breeze!!!

Not Compatible with Optimum (cablevision) Altice USA . Stuck on flashing Online would not Lock on.

I’ve had this for almost one year and my internet provider says it will not ever get faster speeds than about 400. Currently I’ve been getting 87mbs. I’m trying to discover if there’s a firmware fix or am I stuck with a brick.

Highly recommended by my broadband provider. Maximized speed and performance.

Bought this as a replacement for the Comcast gateway and I am impressed with the price, top speed, and reliability. Have had it now for some time and have had no problems. Handles Xfinity internet well.

I just recently replaced my sb6190 modem with a new one (same model). I was told by the cable company that there was no issues with their internet service coming in, and it must be my modem. So I replaced it with the same one because I am very happy with it. Come to find out the problem was with my service provider. So I guess I have a spare now.

Bought the SB6190 last week to replace a SB6141. Another great product. Love the small size. Ready for the future.

I have had this two weeks now after my last one died and it has been working great.

This is my second cable modem. Upgrading. This works as intended and installation was very easy. The only "ding" keeping it from being a 5-star is that the LED's are very bright and I have mine in a guest bedroom. This particular model does not have the ability to dim or eliminate the LED display at night. Perhaps Arris can work on that, as some of their other models do.

Upgraded to this modem & fixed our problem with using the internet

This modem has exceeded my expectations.. Not one issue buying this device.. Bought the router to go with it and not one movie has any lagging

Working well. Fast speeds compare to previous version modem. But sometimes disconnecting suddenly and reconnecting automatically.
