Title: Works Perfectly - No Problems After Several Months
Review: This Surfboard SB6 183 has not had a single problem in the time I've owned it (several months).We use it with MAC OS X, Android and whatever Roku uses.We consistently get our plan's rated speed from the cable provider (30 mBps down & 5 mBps up). Once in a while, we get over the speed we pay for (when the cable company goofs) and this modem is more than happy to oblige.Al channels bond all the time, so that's a good thing for maintaining speed. Actually this modem does a better job of maintaining speed in the evening (when the "Netfilx Effect" slows our cable) than the ISP's rental modem. We can still get 30 mBps.) I've never speed checked & got lower than what we pay for. (Good marks for Wowway and Arris)We can surf the innner-tube-web-net while both of our televisions are streaming educational documentaries on PBS. (OK- Chick flicks & monster movies) This modem doesn't even break a sweat- even in the evening.Tech support is excellent. When i first got it, it would not register on Arris' warranty registration page. Apparently it was already registered to someone else & they must have returned it. My call to tech support was answered by a real, live English speaking person in 1 minute. The technician fixed the problem in less than 2 minutes and offered to stay on the phone while I connected it, just in case I had a problem. Cool, huh? Cheerful guy, too.Connecting it was simple. All I had to do was call the ISP and they did the rest. They could see that it was registered to someone else and Arris fixed it. Once I reached a person at the ISP (20 minutes), provisioning it took about 3 minutes. Simple! The provider is Wide Open West (Also called "Wow" or "Wowway")I did have a problem with setting the Energy Saving feature. The manual's procedure didn't match what the screen said. I wrote to tech support. About an hour later I got a reply. One has to unhook it from the ISP to set this feature. The manual skipped that part. Oh well!Later, I wanted to re-boot it for a test in case the power ever goes out. It would not re-boot, following the manual's procedure. I called tech support. One minute later, a person came on the phone. He said to unhook it from the ISP cable to re-boot it. (Again- Excellent tech support. Crummy manual, however).Note that when we have had power failures, it does re-connect to the ISP with no intervention on my part. I gusee you only have to unhook the ISP cable if you are doing a software re-boot.The actual device runs cool. Very cool actually. This is probably because of two things: The venting pattern and the fact that the power supply is not inside the device. This is good & helps the circuitry run cooler. Actually, since the power supply is a (little) brick- and the brick is outside, it runs cooler too. (And can be replaced wth a generic if needed.)It plays well with my TP-Link Archer C7-AC 1750 router. There are no family feuds between them.Report Card:Performance = A+Reliability = A+Easy Of Connecting = B (Only because of the registration problem)Temperature = A+Compatibility = A+Tech Support By Phone = A+Tech Support By E-Mail = A+User Manual = It's Off To Summer School for Those Writers.Personally, if this ever needs replacing, I will buy Arris again. And, I will buy it on Amazon.Why Amazon? They helped me out when the first one I bought (from a private seller on Amazon) turned out to be second hand and, per Arris, possibly bootleg. (So much for cheaping-out & not buying from Amazon...)So, I do highly recommend this device.If it ever messes up & Arris can't help out, I'll update this review.

Title: Cheap and effective
Review: Good for most providers, used it on xfinity with no complaints. This is a very reliable modem that should last for years with no drama. I prefer the standalone modem to the all-in-one models that include routers and wifi I won’t use.

Title: Very Disappointing. You get what you pay for!
Review: I purchased a refurbished Arris SB6183 in Feb 2019 and it stopped working in Sept 2019. This puts me 4 months past the 90 day warranty offered with this item so I am just eating the cost.The modem worked perfectly when first received and was reliable for 7 months. Today the ethernet port on the back of the modem stopped working, so although my service provider was able to communicate with the modem, send reset commands and perform speed tests, the modem itself provided no connectivity to the outside world for any other device. It was fortunate that I kept the old modem as I was able to plug it in and resume service immediately.I understand the risks that come with purchasing refurbished devices and believe the seller intended to offer a good product at a discount. Unfortunately, not all refurbished items are created equal and in some cases the device dies a few months after the warranty period. I would not recommend making this purchase as there is no way to ensure other modems have a longer useful lifespan.

Title: Shhh… This is the secret your internet provider doesn’t want you to know..
Review: Are you tired of paying an additional $10-15 every month to your already greedy internet provider like I was? This modem is the secret that I don’t think they want you to know. In just a few months this item pays for itself, and in the long run can save you hundreds of dollars. A lot of cable companies don’t advertise that you can use your own modem & router many of them want you to use their equipment for a small rental fee every month. I was tired of paying their fees and then being stuck with the burden of returning the rented equipment anytime I moved. Installation and setup was easy, all it took was one call to my cable provider read them a few numbers they send signals and ask you to turn on and off the router a few times and in a matter of minutes we were up and running. I have Xfinity in my area (Comcast) and it works just fine. I pay for just about as basic high speed wifi as you can get, and I’m getting speeds well above the advertised range from my provider. This modem is small, stylish, and works well with just about any router. I have mine plugged into a Google Nest router. The white & white duo of both devices in my opinion looks a lot better than the big bulky black routers and modems of the past. Had no issues with the modem being used or showing as in service by someone else as other reviews may mention. Everything in the box looked brand new. Router runs warm, not hot, but just a little warm. I have it in a well ventilated area on a side table in my living room and haven’t had any issues.
