My internet speeds more than tripled!

I was having trouble with my cable internet connection for about a week and called my provider and they said they had no issues on their end. My modem, which I own, was over 5 years old so I thought maybe something was going bad with the modem so I decided to swap it out with a newer one. I like to own my own modem instead of paying over $100/year to rent one. I only get cable internet with no TV or phone as I just do antenna for TV and don't care for a landline. I shopped here on Amazon and found this ARRIS SURFboard SB6183 Modem as one of the lowest price modems out there. I received this ARRIS SURFboard quickly from Amazon Prime and installed it and called my cable company to give them the new MAC address. At the same time I inquired about faster speeds since I was on their lowest-tier 100Mbps down/3Mbps up plan, but the rep told me that although I'd get faster speeds (either 150 or 200 down) I would have a data cap whereas now with my grandfathered plan I was on unlimited data. Not to mention the cost would jump from $55 to $80/105 per month, so I'd rather pay less and have the unlimited data than the faster speed, so made no change to my plan. Initially when this new ARRIS SURFboard was up and running I did a speed test and got my standard 103Mbps up/3.1Mbps down. All was working well. Fast forward a month or so, I got a new 4K TV and 4K Apple TV streaming device, and last night I was checking out apps on the 4K Apple TV. I ran across the Ookla Speedtest app and thought I'd install that and check to make sure I was getting the 100/3Mbps speeds in my basement (I have a wireless Apple router for my laptop/phones/iPads but use wired gigabit ethernet for all my media devices). I ran the Speedtest and to my surprise WAS GETTING 343Mbps DOWNLOAD and 32Mbps UPLOAD! HOLY COW! Was this a fluke? I ran it a second time, same results. I had my iPad near me, and tested my internet speeds using Speedtest on that, and got the same results! This was late at night, around midnight. When I woke up in the morning at 5:30AM I tested my iPhone 8 Plus on WiFi and got 267Mbps down and 31.7Mbps up. So something obviously happened with my internet connection. I'm not sure if the rep I spoke with knew I wanted faster speeds and did something to my account to give me faster speeds, or what. I just checked my provider's supported modem list, and the Surfboard 6190 is listed but not this lesser 6183, which is 32x8 vs 16x4 channels, so maybe that has something to do with it, I dunno. I'll keep checking the speeds over the next few weeks and report back here if I end up getting throttled back down. For now I'll enjoy these lightening fast speeds, especially as I download 4K content!

Boom Shaka Laka -I have Internet - Easy Install Level One

I've been dragging my foot and being lazy and paying the big corporation by "renting" the standard modem for a few bucks a month. The "rental" is old and its actually not worth "renting". I think this equipment degrades and limit my internet capabilities. I decided to buy and upgrade with ARRIS SB6183 recommended by my personal research using the slow internet. Since I installed it today, I'll finally start saving in a few months, hey look they even gave me money back and credit. whoohoo. I only surf and watch online movies and besides this modem is great even for future high speed upgrades to play more Online MineCraft if needed. (checkout the specs if your into high speed packages from your provider, there you go, yup, it can handle your slow A....). This is America 'yo" internet speed is like your parents trying to Instagram, Old fashion and slow. At least maximize the usage of the capability using this modem and stop paying big companies. Be the millennial. be hippty hoppity. Anyways I keep hearing about DOCSIS 3.1 but its not worth it at the moment to pay extra. I'll make my return and if I need to upgrade in future. Not worth it now. Kinda like your car, everything depreciates, might as well get your money's worth paying low until its really really necessary again. Bought me a big chicken to cook with the money I saved. It has one cable input to screw on your cable, power cord port to get power from your outlet, and one Ethernet port. If you need extra ports or wifi , just buy a separate router suited for your apartment or home. If you are renting like me, just call your provider, tell them the model you have, the S/N number and the MAC address, (P.S. its the sticker on the modem, they even give you a printed copy) they'll activate it, the provider will then to send command to reset after activation, then BOOM SHAKA LAKA. you have internet back. Don't worry its only 15minutes, you can survive without the internet. If you must, just use your cellular plan to un panic your unhooked life for those precious moments.

Good modem if you use Comcast

Great modem, makes me a little glad my old one died. This modem replaced another Arris Surfboard that was about 4-5yrs old and was very reliable up until it died. So I did some searching for a new modem that would work with comcast. It lead me this modem. I read the reviews and they were fairly good. Once I got my new modem it was a breeze to connect in fact as soon as I hooked the modem up things started happening. After confirming my new modem I tested the connection and it was pretty good. The real surprise was how much faster my download speeds were. They are 3 times faster and while I believe this new modem can take some of the credit but I'm guessing my old modem was kind of outdated and slow. So in the end things worked out for the best. And as for the LED lights and there brightness, they aren't any brighter or annoying than my old modem so no issues. As far as the ambient temps from this modem its slightly warm but not bad at all. I have central air conditioning so I'll guess that heat probably wont cause this to fail. My feeling is the price is fine and it beats renting a modem. I've notivced that my WIFI likes this new modem too. I have a smart tv connected to my WIFI and its connection has been better with this new modem for whatever reason.

Stop renting your modem and own it like an adult

Are you paying Comcast a $10/month (or more) fee to rent a modem? If so, buy this and thank me in 6 months when it has paid for itself. Those pieces of junk your ISP rents to you are no better. How much do you think Comcast pays for a modem/router before charging you $120 a year for it? (Hint: about what this one costs) Lets say you are like the average person locked into an ever-increasing contract with your ISP. You've probably been renting a modem for 5 years (60 billing cycles) and paid over $600 in rental fees! Now, since this is just a modem you will also need your own wireless router. Believe me, its worth doing. I use this surfboard with a linksys router, I've had a good reliable connection the whole time. Even though ISP's periodically obsolete older models, you can buy a new modem AND router every 2 years and still save money over renting. Your internet will be more reliable. Your family will thank you. Women will want you. Men will want to be you. Grow up and buy a good modem. This one works. It's the third Arris Surfboard I've owned.

Comcast users take note: Delivers a little extra "free" bandwidth on 105Mbps and 150Mbps plans

Note: This is for the SB6183. This listing has since been updated to include other cablemodem options. Presumably the seller wanted to make sure people with links to the original product didn't miss that there were newer options. Even in a 105Mbps or 150Mbps Comcast region, this modem is worth consideration. Most of Comcast's DOCSIS 3.0 cable modems have only 4 or 8 bonded channels, while most of their regions support bonding 16 downstream channels. This modem has 16 channels available. While 4 and 8 channel units are capable of delivering Comcast's promised speeds, users will be more subject to local congestion. With cablemodem, you share channels with your neighbors. You benefit from full speed on each channel when neighbors are idle, but if neighbors are consuming bandwidth the channels have contention. When more channels are available, DOCSIS cable modems can distribute traffic between more potential channels. As channel usage drops, your modem's traffic will shift to less-busy channels. For comparison, I upgraded from an 8 channel modem to this 16 channel modem. Old modem: On a 105Mbps plan, I typically peaked at 105Mbps while maintaining about 95Mbps. With 150Mbps, I peaked at 150Mbps while averaging about 125Mbps. This modem: 105Mbps plan peaks at 140Mbps and maintains 105Mbps. 150Mbps plan peaks at 180Mbps and maintains 150Mbps. In other words, on the very same plan, I enjoy 10-20% faster downstream with the hardware as the only difference. Results will vary from area to area, depending on the state of Comcast's network. They're preparing for faster speeds in some areas and upgrading equipment in advance, but other areas without competition may tend to linger on less advanced hardware.

Great product and work fine with Optimum Online

Activated on Optimum network in Connecticut. It works great. Replace Optimum offered Arris TM822 which is now charge me monthly fee. After detach the TM822 and attach this SB6183, Optimum network was able to detect this modem right away. However, I had bad experience with Optimum tech to activate/register this modem. Optimum tech claimed that this modem is DOA. (which I don't believe it. I purchased this unit from Amazon brand new.) Next day, I tried myself. (This applies to Optimum Online only. Never tried on other ISP.) I hooked up the coaxial and used the Ethernet cable to connect to laptop. Open the browser and register this modem to the Optimum Online network by myself. You just need your Optimum account and service information. I was able to "Register" this SB6183 less than 5 min and able to get onto Internet through my internal Wireless router fine. In short, this modem works fine with Optimum network, although it is not printed outside the box. Secondly, no need to call Optimum to swap this modem. You can just register this modem by open the browser and look for "Logon to Network icon" from your browser, follow the steps. That is it.

Arris SB6183 is an Excellent Choice if DOCSIS 3.1 Does Not Work for You

I originally attempted to upgrade my Arris SB6141 with the most advanced net connection tech available in my area. Motorola Ultra Fast DOCSIS 3.1 Cable Modem, Model MB8600, plus 32x8 DOCSIS 3.0, Certified by Comcast Xfinity, Cox, and more It ran amazingly fast but, at my location, Comcast does not provide a clean enough line to maintain a stable 32 channel downstream data flow. This modem constantly dropped the signal, repeatedly needing, hard resets, countless times per day. I then decided to upgrade to the ARRIS SB6183 with its 16 downstream channels. Upon connection and provision by Comcast . . . VOILA! A stable, much faster broader-band connection. It isn't near as fast as the iffy DOCSIS 3.1 connection, but is decidedly faster and is less susceptible to slowdowns during peak use hours, than the SB6141. So, until the cable infrastructure and various broadband delivery hardware from the original components installed in the 1970's are upgraded, I do not see the promises of DOCSIS 3.1 fulfilled in my area. Guess none of us should hold our breath for cable upgrades. The new 5G cellular standard is expected to provide gigabit broadband wirelessly. That explains to me why my cable company is now bundling-in mobile phone services that charge only for data. Cheers.

Great Modem, Affordable Cost - Room for expandability

After trouble shooting a network issue with my home Wi-Fi (for months) I finally figured out my issue was with my modem and not my router. My devices would loose WiFi connection once or twice a day, not realizing it was the modem dropping signal. I pay for 175 down and 6 up, so needed a compatible modem. So it was important to have 16 download and 4 upload channels (in case I increase bandwidth also). This modem fit the bill technically and also had good reviews. Simple to connect, literally plugged it into my existing network, waited for everything to synch up, and self activated via Xfinity website. Literally had the network up and running in 10 minutes and not a single dropped device since. Small in size, but powerful output - no complaints with the SB6183.

Stop paying (service provider) equipment rental fees

Fantastic! - works with comcast so save the highest rental fee in the country of $10 per month for the comcast modem - ridiculous Comcast says it should be able to provision the unit in a few minutes - mine took 2.5 hours............ not the product - it was comcast other than the comcast 4 port modem / router you will need to ensure you connect you incoming cable to this modem then ethernet form this modem to your router from your router to your devices or expansion switch ( I know this is elementary, my house was originally setup comcast modem /router 1 port to expansion switch and 2 port to router) s

Works well with Optimum Online in New Jersey

Since signing up for Optimum Online, the only cable internet service in our area, I was frustrated to find my internet speeds would often become slower than expected. After having the repair technician come out and take a look he replaced our modem. This process would repeat itself again in the near future, but without the resolution of our speed normalizing. The second time the technician came to our home he suggested purchasing my own modem. Not only would I be saving $10 a month on our bill, but we would likely have better luck with a brand new modem, when compared to the modems they provided which were all refurbished. So I purchased this modem and set it up. I had to call up Optimum and give them the MAC address and model of the modem. After a bit of back and fourth it was setup and working. The device is quite small and I like how I can disable or modify the color or visibility of the LED lights. I haven't had to restart the modem or anything recently, and I like how I can login and review the statistics of the connection. Do yourself a favor and purchase a cable modem like this one, you'll save yourself time and money!
