Review: Great modem - increases connection stability - note on setup. - Pros: - Great speeds - Stable - Easy to setup (see note below) Cons: - Runs warm - Bright LED lights I bought this to replace an aging DOCSIS 2.0 modem I had been renting from Time Warner Cable (and had, over the years, paid enough in rental fees by many modems - gulp). It works great with the TWC service and based on standards and prior experience, I see no reason it wouldn't work with all major providers. As others have noted, you get a minor "speed boost" over older modem - this is not due to an increase in sheer maximum speed, since that is set by the cable company, but rather due to the ability of this modem to bond up to 16 channels maintaining the maximum speed more stably (instead of the speed bouncing up and down). The only thing that troubles me about this device is the fact that it does get fair warm to the touch - so make sure it's in a well ventilated area. The blue LEDs in the front panel are also very bright - and even if you wanted to cover them up, you can't effectively block the light as it comes through the main body (sides and back) of the device which cannot be covered due to the need for ventilation. This isn't a problem for me since I keep it in a "wiring cabinet" with plenty of ventilation and a door to block the light, but I can see it being an issue for some. Note on setup - I attempted and failed to be able to use TWC's "auto-setup" so I called their support line. They told me there was an "outage" in my area so while they would enter the data, I wouldn't be able to use the modem until the outage was repaired. This was curious to me, since my internet worked perfectly with the old modem not 30 seconds before. So, with the guy on the phone (without him telling me to), I unhooked this new modem and re-plugged in the old one...suddenly he tells me the outages is fixed and he's able to provision the new modem. Strangely, as soon as he enters the new modem, the "outage" reappears. So again, I switch modems without him telling me to (now having the new one plugged in) and boom, outage gone and new modem works like a charm. Long and short of it? If TWC doesn't see the modem they have in their system plugged in and powered on, there's an "outage" and they can't install a new modem. So if you can, plug in both your existing modem and this new one at the same time (maybe in different rooms) and they'll be able to set the new one up with no issues - in fact, auto-provisioning may work.
Review: Nice hardware. - Nice modem offering potential higher bandwidth, however I live south of Detroit and have the ever so wonderful comcast and unfortunately, nope they weren't hiding any higher bandwidth tiers unfortunately. Still 105M max. Modem physical install as always was simple and easy and even the router/modem played nicely together this time around(replaced a sb6121 and it took me about a month to geta d-link N dir-615 route to play nicely with the 6121). This time around it was with an ASUS RT-AC66R running completely stock fw ATM. Now the funtimes begin(as I expected, I half dreaded receiving the modem knowing what likely pits of pain were awaiting me but foolishly the afternoon of the day that I received it I had a few minutes and decided WTH install it). Everything looks smooth no router/modem problems, modem syncs up to the cable network, run the activation via browser. Everything looks OK until: OK, let's check speedtest and just to be nice(?) let's let it run off the locally hosted comcast server. 6183: 30M down/ 6M up... hmmm... (I'm on the 50M/10M plan ATM, 105M is unfortunately max here, small joke) 6121: 60M down/12M up... Check the modem status, 8 channels down, decent SNR, 3 up good power. Spend some minutes trying to remember WTF my comcast id/pw are(yes I use their "services" quite a bit ;) ), acct #/etc. were phailwhale as usual. OK, both modems show up in my account. Seems AFAICT that the 6183 is active. Take the dive into the depths of hell and CALL comcast(I know what awaits, but I usually come off on the plus side with a lower bill and better services, so WTH). Get the usual I can sort of speak english but also have the added detriment of being in an EXTREMELY NOISY room CSRs which makes for great fun trying to understand them(be OK w/o the extreme background noise). Play the script game, MAC addr, try to resend config nope. Insert some feeble upselling, which for some reason didn't seem to have actually been entered as he offered a good price for 105M v. what they advertise, but my acct still shows 50M. End up randomly scheduling a "tech" (and I use the term loosely) to come. (By this time the 6183 has disappeared from my account, but it's still passing data, so I leave well enough alone FTM plan). Fortunately I am home when this guy shows up(noticed the van there as I'm about to leave. And ask him if he's here for this address.) So we get re-add modem to account(mysteriously disappeared see above), apparently is sent correct config this time(but not achieving anywhere close to perf of 6121 not to say that 50M is anything to write home about). Also find out SURPRISE SURPRISE that there's apparently a line problem somewhere with 185' of my house. (I say surprise as comcast NEVER EVER does ANY plant maintenance, even DTE shows up every 15y or so to hack away at trees.) So yeah, basically the modem seems good. My only real complaint is the log file will not default to the December whatever it was/1970 date if it cannot sync up time, just puts the oh how helpful "Time Not Established" in the time/date field and then the log message. At least if it defaulted to the 1970 date/time I would have a relative offset as to how far apart the log messages are spaced. The sb6121 had that behavior. This is putting me right back on the hoping for FTTP before I croak train though, thanks to the ever so wonderful comcast.

## Questions & Answers

**Q: I purchased this item almost 8 weeks ago 8 August 2014 will i receive this item in my lifetime or will i need to leave this item in my will for my kid**
A: Purchased SB6183 a week ago, My invoice says estimated shipping between Oct 1 to 10th. What was your estimate date? If i don't see any update by Oct5th i'm going to cancel my order and stick with SB6141.

**Q: Does ARRIS/Motorola support firmware upgrades for the 6183 via downloads to the consumer's computer?
If not, why not?**
A: If there are upgrades, you will be able to download, as you would for any piece of computer hardware. The cable companies do NOT have any control over what you download or what modem you use. It may not work if it's not using the right protocols, but they aren't going to exclude any that do work. And just about ANY gateway/router hardware will work. Again, the cable company has no control whatsoever over what router/firewall you are using.

**Q: What is the difference between this modem, the SB6183, and the SB6180?**
A: The SB6180 enables channel bonding of up to 8 downstream channels and 4 upstream channels, which allows an operator to offer their customers advanced multimedia services with data rates of well over 300 Mbps in DOCSIS mode and 400 Mbps in EuroDOCSIS mode for downstream and 120 Mbps upstream.  The SB6183 has 16 download & 4 upload channels.  Download speeds up to 686 Mbps and upload speeds up to 131 Mbps based on your Cable provider service.  That is the main difference I could find.  I hope it helps.

**Q: do most users need such a fast cable modem? I have comcast performance....is this over kill or futureproofing with docis 3.1 on horizaen.**
A: DOCSIS 3.1 is here, true. And the first set of cable modems using the standard will offer some improvements. As with many technologies, they don't saturate the market overnight. In most cases the availability and maturity of a technology in the marketplace can take years - as much as 3 to 5 years. Even if 15 to 20 percent of the market goes to DOCSIS 3.1 in the first or second year, that says 80 percent hasn't. Future proofing your technology is nice, but a measure of sensibility should be used too. I went to the ARRIS SB6183 knowing that my ISP service is 200 Mbps. It allows a considerable cushion for growth. If my ISP's average speeds jumped to 500 Mbps, and I were to consider another cable modem upgrade, I would focus on a faster cable modem that uses the DOCSIS 3.1 standard or any newer and more powerful standard - allowing me to benefit from the latest standards and speeds. The DOCSIS 3.0 standard may well be nearing  its End-of-Life in 2 to 3 years. Therefore, I would see no value going to a 1.4 Gbps DOCSIS 3.0 modem.

### ⭐⭐⭐⭐⭐ Works Perfectly - No Problems After Several Months
*by P***B on June 28, 2019*

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.
