Having the best modem and router to use your internet service lets you enjoy its full benefits. To know the best, there are a few qualities to consider. These qualities include speed, number of bands and other features like DOCSIS and Ethernet port.

Aside from these qualities, it is also crucial to check out compatibility with your ISP. This is because some modems are incompatible with certain ISPs, and nobody wants to waste money on a modem that doesn’t work for them. After looking at all these qualities, we have put together a list of the best Modems you can use for Cox internet. Keep reading to learn about them!

Arris Surfboard S33

The Arris Surfboard is widely regarded as one of the best Modems out there. You can hardly make a list of the best modems for the leading ISPs without including it, and for a good reason. If you use the Gigablast plan, you will have a wonderful experience with the Surfboard S33.

The modem supports DOCSIS 3.1 standard with 32 downstream and 8 upstream channels. It has a 1 Gigabit Ethernet port and a 2.5 Mbps port. Theoretically, it has a maximum speed of 3.5 Gbps and 1 Gbps with a wired connection.

It is future proofIt is costly
It supports DOCSIS 3.1 standardConfiguring it is difficult
It supports all Cox plansIt’s an overkill for mid-range and low-speed plans
It has multiple ports

These qualities of the Arris S33 show that it is for those willing to splurge the cash to enjoy Gigablast plans. If you are no such person, wait!

Motorola MB8600

This is another mainstay in the list of best modems. Like the Arris Surfboard, the Motorola MB8600 supports the DOCSIS 3.1 protocol and 32 downstream and 8 upstream channels. However, it has only a standard Gig ethernet port.

One feature that makes the MB8600 great for streaming and gaming is its extremely low latency. It also supports the Gigablast plan. Other qualities of the Motorola MB8600 are auto-configuration support, multicast routing and zero address collision.


It supports all Cox plansIt has only one Ethernet port
It supports DOCSIS 3.1 standardIt is expensive
It has an exceptionally low latency
It is future proof

It is easy to see from the information above that the MB8600 is not for people on low-speed plans or a budget. Again, wait!

Netgear CM1100

The Netgear CM1100 is something of a universal modem that is compatible with numerous ISPs, and Cox is no exception. The CM1100 runs the DOCSIS 3.1 protocol with 32 downstream and 8 upstream channels. Additionally, it has the Quality of service (QoS) feature, which allows you to prioritize certain devices over others.

This device also comes with two gig ethernet ports, making it easy to set up wired connections running at high speed.

It runs on DOCSIS 3.1 standardIt can be excessive for the average individual
It has two Ethernet ports
It is future proof

Another feature of the Motorola MG8702 is comprehensive security support and Quality of service. It also has four Ethernet ports with one USB 3.0 for network media sharing.

Motorola MG8702

This device offers the best value of all modem-router combos compatible with Cox. It supports the DOCSIS 3.1 protocol with 2×2 OFDM technology, which proves useful for heavy internet needs. Additionally, it features 32 downstream and 8 upstream channels while being compatible with older DOCSIS standards.

It has four Ethernet portsThe router doesn’t support WiFi 5
It supports DOCSIS 3.1
It has minimal latency

While this modem-router has a collection of qualities that make it great, its lack of support for WiFi 6 is a knock on it. However, it is still great if you don’t care for such things.

Netgear CM700

The Netgear CM700 is one of the few budget modems with almost all the features of the more expensive modems. Powered with the DOCSIS 3.0 standard with 32 downstream and 8 upstream channels, the Netgear CM700 also has the Quality of service feature, which lets you prioritize some devices over others.

The device features a single gigabit Ethernet port that Netgear promises will give you the highest wired speed possible.

It is perfect for mid-range to low-speed Cox plansIt doesn’t support gigablast plans
It is cheap when its qualities are consideredIt runs on DOCSIS 3.0 standard

Although not a modem you’ll buy to use for years to come, the CM700 is good enough to do the job if you are on a budget.

Arris Surfboard SB6190

The Arris Surfboard SB6190 is the budget modem on this list, as not everybody is interested in the gigablast plan. For plans with lower speed, it does the job to the tee.

The modem uses DOCSIS 3.1 protocol with 32 downstream and 8 upstream channels. It also has an ethernet port that can reach a maximum speed of 1 Gbps.

It is budget-friendlyIt doesn’t support gigablast plans
It is perfect for mid-range plansIt has only one Ethernet port

This is another modem that won’t serve you well if you need the fastest internet plans. However, if you use mid-range and low-speed plans, it is perfect.


After considering multiple factors like cost and features, we have come up with the above six modems as the best to use with Cox internet. As some people need high-speed internet while some use a medium to low-speed internet, we ensured that both parties are satisfied. What are you waiting for?!
