7 Best Approved Cable Modems For Cox

This data is based on extensive research. This includes reviews for COX cable modems from multiple sources. This list is also based on feedback, pricing, availability, and information provided by COX. This ensures you’ll be getting the best modem for your COX Internet service.

1. NETGEAR Cable Modem CM600

If you’re on the Ultimate 500 plan and don’t want to future-proof, the CM600 may be a smart option. You want something that works well right now. DOCSIS 3.0 cable modems support 24×8 channels. Although this modem is sufficient for all except Cox Gigabit plans, it does not work with the Cable ONE Internet Plus plan (you’d need an even faster modem).

This bundle includes a CM600 modem and the correct value-add services for an excellent cost. It’s DOCSIS 3.0, so no one knows how long it will last. Cox is phasing out DOCSIS 3.0 modems, recommending that customers upgrade to DOCSIS 3.1 modems instead. If you’re on a slower internet connection but want to save money, the Netgear CM600 is a fantastic option.

2. MOTOROLA MG7540 16×4 Cable Modem Plus AC1600 Dual Band Wi-Fi Gigabit Router

The Motorola MG7540 modem/router combination is the best option for budget-conscious consumers with the Cox preferred 150 or lower plan. At a distance of 5 feet, it delivered a speed of 301.85Mbps, and at a distance of 25 feet, it produced a speed of 102.38Mbps. Both were obtained from the 5GHz network.

Although these results are not outrageous, they are acceptable given the price tag. It should be able to comfortably support three to four users utilizing the internet simultaneously without difficulty. The cable modem uses DOCSIS 3.0 channel bonding (16×4 channels). While this isn’t guaranteed to work in the future, it may still be useful for another several years

The biggest disadvantage of the MG7540 is its limited range. During testing, it only reached 70 feet. It would suffice for a normal-sized home if positioned in the center of a household. It’s ideal for an apartment with about 150 square feet of space. With the Preferred 150 Internet packet and a medium-sized or smaller property, the MG7540 is an excellent option for you.

3. ARRIS SURFboard SB8200

The Docsis 3.1 modem on the SURFboard SB8200 offers a wide range of features, including streaming Ultra HD 4K videos and high-end gaming on a PC. It had no latency and maintained consistent 2Gbps download rates and 1Gbps upload rates during extended testing. Two Gigabit Ethernet ports can be used to establish two separate home networks. This allows visitors to use a single network privately, as it supports both IPv4 and IPv6 Internet protocol standards.

The SB8200 provides 32 downstream and eight upstream channels, making it simple to link numerous devices at the same time. The modem is powered by a Broadcom BCM3390 chip with 3GB of memory. There are two Ethernet ports on the modem. You may connect a gaming console as well as a wi-fi router to each port utilizing this. A WiFi router isn’t included in the package, so, this is an issue.

4. NETGEAR Cable Modem Wi-Fi Router Combo C6250

This device is suited for users who are on the COX Ultimate speed plan (up to 300 Mbps). The Netgear C6250, on the other hand, will be limited to the Ultimate speed Tier. The Internet Preferred 150 plan works well with this router. It has enough room for growth. The C6250 combination device is one of the most cost-effective solutions available today.

It’s perfect for medium-sized homes because it covers roughly 1500 sq ft and accommodates up to 25 wifi gadgets. This model has been successful in the market for many years.

Before you install the gadget, contact COX. They may need to register your new MAC address. It also features a USB port that may be used for connecting a storage device, among other things. The ReadyShare software allows you to back up files and share them using the Netgear C6250’s USB port. For moderate bandwidth demands, the Netgear C6250 is an excellent option.

5. ARRIS Surfboard S33

If your Cox Internet service will be upgraded to more advanced internet device hardware and you want to subscribe for a multi-gigabyte plan, the Surfboard S33 is a good choice. The modem uses an ARM-based chipset that improves functionality. This characteristic helps you avoid network congestion and interference, making it more responsive than ever before.

The SoC’s 1.2GHz frequency ensures that the SoC can handle multiple data streams and cut through interference. 2×2 OFDM/OFDMA support is also included in the chipset. This feature enables fallback to 32×8 channel bonding in case of DOCSIS 3.1 loss of connection with ISPs’ head ends.

The Arris SBS33 has more advanced channel allocation in both the frequency and time domains, allowing the router to transmit data packets with greater efficiency. Single-Carrier QAM support is also available, which allows for smooth transmission and modem compatibility with multiple ISPs such as WOW!, Comcast Xfinity, Spectrum, WOW! Cable, and many others.

Although the Arris Surfboards S33 can operate at 3.5Gbps when fully utilized, I am confident that you will not be able to achieve this speed with a Cox internet service. Even though I had a Gigablast Cox Plan, I was able to download speeds of up to 1Gbps. When connected to Wi-Fi AX routers, upload rates may reach 100Mbps. Other providers on the market do not have as fast internet speeds as Cox does. It is a good idea to acquire a Cox Gigablast modem like the Arris Surfboard S33 because it will lower subscription fees and allow for future increases in speed.

You also get a two-year warranty, which is backed by a helpful customer service team that is available 24/7.

6. Motorola MG7550 Modem WiFi Router Combo with Power Boost

The Motorola MG7550 cable modem is the best option for Cox internet. The router in this dual-band modem can handle your WiFi network. Power Boost is also available to boost signal strength and speed. Selecting between the 5GHZ and 2.4GHz bands is possible with dual band technology. You may connect your computers, game systems, and HDTVs to four 10/100/1000 Gigabit Ethernet LAN ports using a wired connection.

The router is embedded within the modem, which improves connection speed and minimizes interruptions. It also saves space. It’s space-saving in that it doesn’t take up much room and features a vertical antenna-free design.

7. Motorola MB8600 DOCSIS 3.1 Cable Modem

Connect to high-speed internet with confidence that your modem can handle anything. The Motorola MB8600 is among the best modems always providing exactly what you need for a high-speed Cox connection. With Gigabit plans becoming more popular, the router may give you trouble when trying to keep up with demand due to which you will be required an excellent cable modem.

Luckily this DOCSIS 3.1 modem supports any gigabit provider both 32×8 channels for DOCSIS 3.0 and 32×8 channels for DOCSIS 3.1 so it can grow with your needs! If you’re looking for something fast and reliable then consider purchasing the Motorola MB8600 today because it’s just what you want!

These COX cable modems are older modem/router combos with wireless N technology. They are approved by Cox but should be avoided as wireless AC is the most widely used WiFi. On top of that WiFi AX is coming around, really making N older.

What Cable Modems Work With Cox Communications?

There are a lot of cable modems that work with Cox. Most ARRIS, Netgear, and Motorola modems will work. The most important things to look at when buying a new modem are your subscribed speed, the number of download channels per modem, and the top speed per modem. Here, we have everything laid out for you to allow you to find the best modem for Cox and your service.

Does Cox Supply a Free Modem?

Only if you subscribe to both high-speed Internet and voice service. Otherwise, you can rent a cable modem or buy your own.

What Is The Best Modem Router Combo For Cox?

As stated above, the ARRIS SBG10 is the best WiFi cable modem, otherwise known as a modem/router combo. It is one of the latest releases, has great customer feedback, is easy to set up, and is fairly cheap for a WiFi modem.

What Cable Modem Does COX Rent For Panoramic WiFi?

​The Panoramic WiFi Gateway is the only modem/router combo available for rent from Cox. It usually costs $10.99 a month. It is a proprietary modem sold only to Cox. Cox does not sell this modem to customers. It is only available for rent. However, you can buy a different WiFi gateway that will work with Cox.


Renting a modem from your internet provider can be expensive, but buying one of the Cox approved modems means you won’t have to pay for it. However, this choice does come with some downsides. For example, if you want Wi-Fi in your home with Cox Cable Internet Service, then you will need to purchase a separate router ($60-$200). You might also end up paying more money upfront because these are typically priced higher than rentable models ($150-$300+). But on the bright side, not having monthly rental fees could save you hundreds each year! And even if that isn’t enough incentive there is one other major benefit that comes along with owning your own modem – faster speeds.
