Best Modem for Cox Ultimate

Best Modem for Cox Ultimate – Buying your own modem means you won’t have to rent one, which lowers your monthly internet bill. But it also means you have to do a little more work. Make sure to go with one of Cox certified modems. And if you want Wi-Fi with Cox, routers are a must.

But keep in mind that your equipment will only be as fast as your internet plan, so it never hurts to double check your current service.


1.ARRIS Surfboard S33

As far as modem performances are concerned, Surfboard S33 houses an ARM-based chipset. Needless to say, this attribute makes the modem faster than usual by helping you steer clear of network congestion and interference.

The 1.2GHz frequency of the SoC ensures that you can cut through any form of interference and manage multiple data streams with ease. Plus, assisting the chipset is the DOCSIS 3.1 standard with 2×2 OFDM/OFDMA support, which supports a fall-back to the DOCSIS 3.0 32×8 channel bonding support.

2.Motorola MB8600 DOCSIS

At the core, you have the ARM-powered processor, which helps the Motorola MB8600 manage congested and overcrowded networks. Even during peak hours, you can expect consistent internet speeds, provided the complementing router is properly configured.

As far as the network standards are concerned, the DOCSIS 3.0 support is good enough for standard transmissions. The 32×8 channel bonding spread is at least 8 times faster as compared to a DOCSIS 2.0-specific internet setup.

3.ARRIS SURFboard SB8200

The Surfboard SB8200 doesn’t let you down in terms of processing power. Instead, it on-boards a Broadcom chipset and 3GB of RAM that allows you to manage multiple data streams even when the network is overcrowded.

The DOCSIS 3.0 network standard comes equipped with 32×8 downstream and upstream channels, allowing you to take the advantage of prioritized traffic allocation. But the modem can automatically upgrade to the DOCSIS 3.1 standard, with 2×2 OFDM/OFDMA channels, during peak hours.


Powering this future-proof modem is a Broadcom chipset that also powers the top-shelf Arris Surfboard SB8200 that I mentioned above. Coupled with the processor is 256MB of system memory that can take multi-stream performances to the next level.

This means, a powerful processing setup like the one housed by the Netgear CM1000 ensures minimal signal latency and even works in favor of speeding up the data packets, despite the congestion.

5.ARRIS SURFboard SB6190

The Arris SB6190 features the DOCSIS 3.0 network technology with 32×8 channel bonding support. When it comes to speed-based comparisons, the modem can transmit data at least 8 times faster than a DOCSIS 2.0 setup.

The 32 downstream channels, however, are great when it comes to scaling beyond network congestion. Also, as upstream requests are lesser as compared to downstream transmission, 8 channels are more than adequate.


At the core, Netgear CM700 houses a reliable quad-core processor that can clock at speeds of up to 1.6GHz. This enhancement cuts through congestion and helps with the additional workload experienced through the peak hours.

If you are an active gamer who is worried about the latency, the 128MB RAM coupled with the DOCSIS 3.0 standard ensures high-grade performance. The DOCSIS technology thrives on the availability of the 32×8 downstream/upstream channels, which leads the way with QoS support.

7.TP-Link Archer CR700

The TP-Link CR700 fits in a dual-core processor that works together with 256GB of RAM. The feature processing setup allows the router to maintain steady internet speeds and scale beyond lags and congestion.

As far as the modem-specific capabilities of this device are concerned, the DOCSIS 3.0 setup allows you to make the most of the ISP’s internet plan. Also, the 16×4 channel bonding support allows you to assume 4 times better speeds as compared to a DOCSIS 2.0 device.
