10. Cheapest Modem/Router Combo for Suddenlink Arris SurfBoard SB6121

Arris SurfBoard SB6121 by love2java

 

  • Docsis Tech: 3.0
  • Downstream / Upstream: 4 / 4
  • Download / Upload Speed: 172Mbps / 132Mbps
  • Modem / Router Combo: Yes

The Arris SurfBoard SB6121 is a Docsis 3.0 based modem-router combo. The model has different options for speed and channel if you are willing to pay more but even the minimum option one has amazing speed. It easily hits the 172 Mbps and 132 Mbps download and upload speed limit and even surpasses it. Of course, it is still somewhat dependent on your ISP.

While we weren’t particularly bothered by the blue LED indicator lights, some users have complained about it before. We have also noticed some dissatisfaction with the signal. What we noticed is that the modem takes better to new wiring. The wifi signal is overall strong and the 4 x 4 channel bonding is stable.

The setup and installation process isn’t much of a problem. As long as you understand where to plug in what, you should be alright. The manual does a good job of explaining the initial steps as well. However, it doesn’t really go more in-depth than that. So, if you’re not a tech expert who wanted to tinker with the channel and speed a little, you will need outside help.

Pros
  • Comes with 4 Ethernet ports
  • Easy setup
  • Truly incredible speed

Cons

  • Bright LED lights that can annoy the user
  • Old wiring can mess up the signal
  • Isn’t user-friendly for people who don’t understand tech

11. Arris Touchstone TM722G

Arris Touchstone TM722G by love2java

 

  • Docsis Tech: 3.0
  • Downstream / Upstream: 4 / 4
  • Download / Upload Speed: 343Mbps / 150Mbps
  • Modem / Router Combo: No

If you are in the market for a modem alone, you would like the Arris Touchstone TM722G which uses the Docsis 3.0 platform.

The speed of 343 Mbps for download and 150 Mbps for upload is genuinely fast. Not to mention 4 x 4 channels that give sustained connection without disconnection. It is definitely ahead of its counterparts in the market.

While it is compatible with most cable providers, we all know Comcast is a popular choice. It really does work well with Comcast. As we said, the speed is excellent. However, setting it up can be quite a long process. The modem doesn’t come with the option for you to set it up on your own. You will have to stay online with the tech guys from Comcast for some period of time before your modem can be activated.

Now, while we didn’t have much of a problem with the system, popular customer review suggests a lot of people had to wait for a long time to get the connection right.

Other than that, the modem itself is as good as the claim. It’s accurate more than anything. Compared to the previous modem for Arris, this is significantly better.

Pros
  • Compatible with major cable providers
  • Quite on the inexpensive side
  • Speed is definitely good

Cons

  • You will need good wiring
  • Setting it up with Comcast isn’t easy
  • Might lose connection once in a while

12. Cheapest Suddenlink Compatible Cable Modem: Netgear CMD31T

Netgear CMD31T by love2java

 

  • Docsis Tech: 3.0
  • Downstream / Upstream: 4 / 4
  • Download / Upload Speed: 150Mbps / 150Mbps
  • Modem / Router Combo: No

If you are looking for an affordable modem, then the Netgear CMD31T would be a likely candidate for your purchase.

The modem has a steady upload and download speed of 150 Mbps. It is surprisingly fast. We have tested the speed by streaming and downloading a couple of videos and it seems to do everything without any lag.

Installing the modem isn’t much of a problem. You just have to send the numbers to your ISP so they can activate it and on your end, you have to plug it all in the right way. However, it’s impossible to decipher how easy the installation is because of how bad the instruction guide is. It doesn’t do a good job of explaining anything and whether you understand tech or not, it will get you confused.

As of now, the modem doesn’t have a built-in router. So, if you need an internet connection with wifi in your home, this one isn’t for you. The Netgear CMD31T uses Docsis 3.0 technology and has 4 x 4 channel bonding allowing fast transfer of data.

Further, we were quite happy with the price range. If we compare to the counterparts in the market, this one offers more range than the others.

Pros

  • Definite easy installation process
  • Small, compact model
  • Price is decent

Cons

  • Disconnects from time to time
  • Doesn’t have a wifi or router option
  • Manual isn’t helpful

Suddenlink Compatible Modems: The FAQs

If the budget was not a concern, which would you advise?

Without any hesitation, we would ask you to buy the ASUS CM-32. It is priced at $200 but packed with the latest features and has a very powerful Wifi router. In fact, it does not cost more than a modem and a separate high-quality Wifi router.
On the other hand, you get the convenience of an all in one device that is capable of 1.3 Mbps downloads and sending data uniformly through your home to every device.

Which is a no-frills device for Suddenlink that you suggest?

The Netgear CMD31T is simple but packs a punch. This modem is priced well below $50 but allows smooth 150 Mbps downloads. Don’t sneer because that is enough speed to stream not one but four UHD films at the same time. We tested it for many days and found it to be an aesthetically pleasing, affordable, and capable device.

I want a not very pricey top of the line modem and Wifi combo. Which should I go for?

The Arris SURFboard SBG6580 works on the DOCSIS 3.0 platform that was capable of sustaining well over 100 Mbps during our rigorous testing. It has four Ethernet ports and a dual-band Wifi that takes care of most homes with 3-5 rooms (a distance of 100 ft).

I want a stylish and capable router with no ugly looking antennas.  What do you suggest?

The Netgear C7000 Nighthawk has no external antennas and is capable of AC1900 Wifi. It is certified by the manufacturer for 400 Mbps speed, and we verified it. Powered by internal antennas, the router is capable of transmitting across a medium-sized home without any lag.

Is there a DOCSIS 3.1 modem in your line up?

The Netgear CM1000 is capable of 1000 Mbps+ downloads and is priced attractively at $124. The Genie app is brilliant and allows you complete control over your device by logging in through a browser.

Verdict 

The Arris SBG7400AC2 was our unanimous top choice. Priced quite low, it has McAfee anti-malware protection and looks good in matte black with pale blue LEDs. It offers beamforming that focuses the Wifi signal towards a device instead of spreading it omnidirectionally. There are plenty of Ethernet ports and one USB that allows you to connect in a wired network.

The runner up was the Netgear C3000 modem router. With N300 Wifi, it can support up to 300 Megabits/sec, which is more than enough for most families. There is the innovative AirPrint feature allowing you to print directly from any iOS device and a smart home network manager with an intuitive interface.
