Arris Surfboard SB6190 Modem Review

In order to fully maximize the capability of your network provider, you will also need a capable modem. Now, there are some capable modems in the market, but they also usually come with a high price. That’s not the case with Arris SURFboard SB6190 cable modem. This modem can be bought for only $88.00 from the official Arris website – down from the regular $99.00 price. For a DOCSIS 3.0 modem, the Arris modem SB6190 is a steal.

Features of Arris SB6190 SURFboard

Arris SB6190 is one of the cheapest DOCSIS 3.0 capable modems in the market. It’s not that hard to see where Arris cut corners. But considering its price, which is currently on markdown, it will be really hard to find a competition that could exceed the performance and features of the SURFboard SB6190.

1. DOCSIS 3.0 for Stable Speed

Unlike the older DOCSIS 2.0, the DOCSIS 3.0 on the Arris SB6190 allows for much higher maximum throughput. The SB6190 can do that by using the multi-channel bonding technology, which unlike the older DOCSIS 2.0, can only allow for single-channel down and upstream. This multiple channels can be bond to maintain the regular internet speed even during the peak hours. 

As you will expect from a DOCSIS 3.0 modem, the Arris SURFboard SB6190 can support a maximum of 1400Mbps theoretical downstream data rate, and up to 240Mbps theoretical upstream data rate. Yes, we are already heading to 10Gbps internet speed, but 1000Mbps is already fast enough for the most part. And knowing that most data plans can’t even max out this number, makes the Arris SB6190 a good buy. But if you really need some more speed then you can spend a little more and get Arris Surfboard SB8200 which can get you 2000Mbps of speed or if you need more then just check this beast out – Motorola MB8600.

2. Multiple Channel Bonding Technology 

As mentioned above, it is on the DOCSIS 3.0 where multiple channel bonding technology was introduced. The Arris SURFboard SB6190 supports up to 32 downstream, and up to 8 upstream channels. 

On older DOCSIS 2.0, there is only one single downstream and upstream channel. This is the reason why DOCSIS 2.0 lags during peak hours. What happens during peak hours is that the network traffic is so high that your ISP starts throttling every channel at its minimum speed to keep up with the traffic. Since you only have a single channel for both downstream and upstream, your internet connection will slow down. 

But with DOCSIS 3.0 featuring channel bonding technology, you will be able to maintain the internet speed even during peak hours. This is because each minimum speed available at each 32 downstream and 8 upstream channels will be combined into one high-speed channel to create a fast and stable internet connection. 

DOCSIS 3.0 modems can go as far as 300Mbps at initial speed and can peak at 1Gbps at its final version. Upload speed is lower at only 100Mbps at its initial stage and can peak at 300Mbps at the final version. Compared to DOCSIS 2.0 modes, this is relatively faster. 

3. RF Immunity

Radiofrequency (RF) interference can be a real pain for the modems. An RF interference can be generated by any device that uses electromagnetic signal- that means your smartphone, Bluetooth headset, and even microwave oven can generate a lot of RF that will interfere with your modem. This will cause flaky Wi-Fi performance, spotty coverage, and unreliable connections. 

RF interference has always been a big problem for most modems, except the Arris SURFboard SB6190. The SURFboard SB6190 features RF Immunity technology which shields it away from RF interference.

4. MoCA Reject Filter

Multimedia over Coax Alliance (MoCA) filter is another feature that can set this modem apart from its competition. A MoCA filter will make ensure a stable connection in your home by preventing any potential interference from MoCA going into a modem. This will also make sure your MoCA will not leak out of your residence, and affect modems around the neighbourhood.

5. Gigabit Ethernet

Arris SB6190

The Arris SB6190 features one Ethernet port which can be used to connect to a Wi-Fi router, or directly to your smart TV for that non-stop Netflix and chill, or even to game consoles.

6. Front Panel LEDs

The Arris SB6190 features a front panel LED. These LED lights will help users in troubleshooting the modem with the help of their blinking status. In total, there are four-panel LEDs on the front of this Arris modem. There is a separate LED light for “Power”, “Recieve”, “Sent”, and “Online”. 

If the LED light on the Power is off, that means the modem is unplugged. If the Recieve LED blinks, that means the downstream channel is lost. If it is the Sent LED that is blinking, that means the upstream channel is lost. While if the Online LED is blinking, that means, the IP registration is lost. 

Overall, the find the LED indicators on the Arris SURFboard SB6190 is very helpful to users should they do some manual troubleshooting. 

7. Quick and Easy Setup

Probably one of the most important features for a modem is its setup time. With the SURFboard SB6190, it is a relatively easy setup. At the back of the modem, there are three important things – Ethernet, coaxial cable, and power. 

For the setup, connect the cables: Ethernet, coaxial cable, and power button. Contact your ISP (via a web portal) to activate your unit. Connect your Wi-Fi router to set up your devices. 


The Arris SURFboard SB6190 is a very good product. It launched at a retail price of only $99.00 in 2015 and has since then getting markdowns everywhere. Currently, the modem sells for only $88.00 from the official Arris website. This price, coupled with some great features makes up for a very compelling buy. 

The DOCSIS 3.0 is enough for average internet subscribers. The 1000Mbps theoretical maximum data rate of the SURFboard SB6190 will give users enough power to move forward the increasing data speeds. The modem also features channel bonding technology which will maintain your internet signal speed by combining all the minimum speed per channel – 32 downstream, and 8 upstream channels to be exact. 

Finally, the Arris SB6190 features RF immunity, and MoCA filter to filter out some signal interference in your modem. This is to ensure the stability of the internet signal and solve spotty coverage in your house. 

Overall, we highly recommend the Arris SB6190 for those who want to upgrade a modem to the DOCSIS 3.0 standard. It is cheap and packs a lot of features that are more than worthy of its asking price. Yes, it is old. But the maximum downstream speed it can handle is more than what most internet subscriptions can support.
