What to Consider When Buying a Modem for Comcast Business

Modems are difficult to understand technically. You may be familiar with a modem’s speed and ports, but there’s so much more to it. So, before you choose a modem based on how appealing it looks, even if it performs like a sloth, here are some aspects to consider when selecting a modem.

Compatibility

When purchasing a modem to work with a specific network provider, such as Comcast Business, compatibility comes first. You should check to see if the modem you’re about to buy is compatible with your ISP’s service.

Comcast Business has published a list of network-compatible devices on its website. So, before you make a purchase, be sure the modem is present on their compatibility list.

DOCSIS

Modems are equipped with a specific DOCSIS technology that allows a modem to handle maximum speeds. Currently, most ISPs support two versions DOCSIS 3.0, which use different channels to allow data transfer of up to 1 Gbps per second.

While the latest generation, DOCSIS 3.1, allows data transfer of up to 10 Gbps per second. So, depending on your internet plan, opt for a modem with suitable DOCSIS technology.

Best DOCSIS 3.1 Powered Modems

Internet Protocol

For data transmission through devices, modems also use an Internet Protocol. Internet Protocols (IP) assigns unique IP addresses to internet-connected devices in order to facilitate data transfer.

For a modem to work with Comcast Business modem, it should be IPv6 enabled, which is the latest internet protocol and an improved version than IPv4.

Channels

If you intend to purchase a DOCSIS 3.0 modem, you should also consider the modem’s channels. The channels determine the modem’s speed.

DOCSIS 3.1 modems may deliver speeds ranging from anywhere to up to 10 Gbps using 32 downstream and upstream channels. Modems with DOCSIS 3.0 use different channels like 8 x 4, 16 x 4, 24 x 8 for delivering different speeds. So opt for a modem that has channels that are appropriate for your internet speed.

Product Review

ARRIS isn’t only known for their future-proof and reliable products, but budget modems too. Because of their well-priced and admirable performing modems, the company’s been trusted by customers with a limited budget. The ARRIS SURFboard SB6183 is another product that excelled in the budget competition. 

Following the same SURFboard series design, the SB6183 uses DOCSIS 3.0 for an affordable approach. The modem has 16 downstream and 4 upstream channels to support speeds of up to 600 Mbps. However, in actual, modems deliver less than advertised speeds, so did it.

Still, it performed exceptionally with handling smooth Netflix sessions over various devices. And stole the game over other budget modems that didn’t perform as smoothly as this. 

Even with a low price tag, the SB6183 offers advanced features and a two-year warranty to save the day in case of failure. Therefore, if you’re in search of no compromises and great budget performance, this is your way.
