Arris Surfboard G34

Design and Performance

Compared to what we’ve generally seen with most other Arris routers, this one actually offers quite a visual respite. The modem features a rather smooth and rounded design, unlike the boxlike structures that we are so used to seeing with Arris. On the back, you can find 4 LAN ports and one coax cable port as well, along with one last inlet for the power cord. This makes it a great device for those who wish to connect wired devices such as televisions, laptops, gaming consoles or network printers. In the case of a separate router one or two of these ports would’ve been blocked in connecting with the modem. However, with a built-in modem, all four ports are available. 

When it comes to performance, this modem-router combo really scores a big win. This is a great device for anyone who is into gaming, streaming or any other sort of heavy-duty internet usage-related work. Generally, we see that when it comes to modem-router combos, the routers aren’t really as power-packed when compared to a separate router. However, the G34 from Arris completely shatters that stereotype and has firmly established itself as a top player here. You get a very stable and reliable internet connection when you make use of this router. 

Connectivity, Security, Setup, and Control

While the range and the number of devices that can be connected with this modem-router combo haven’t really been specified, you can expect this to easily provide internet access to an average 2500 sq. ft. 3BHK home. You can also expect it to connect anywhere around 25 to 30 devices at a time. The modem makes use of the SURFboard Central App, which allows you to set up your internet connection, as well as ensure the security of your network from your mobile phone. This even allows you to set screen time parental controls and other network filters with ease. 

Summing up, the Arris Surfboard G34 is not only one of the best Arris products, but also one of the best modems for Cox, as it provides you just the right kind of stability and speed that you’d require for all your needs – be it regular office work or something more power-packed such as gaming.

Points to consider when choosing your modem.

  • Compatibility

The first thing you need to do is check the compatibility of the modem you choose to your ISP (Internet Service Provider). For COX, you will need a DOCSIS (Data Over Cable Service Interface Specification) Cable Modem. This permits the transfer of high-bandwidth data to your TV for example.

  • Affordability

You need to consider how much you are willing to spend on your new modem before you make the purchase. Some research into this can help you decide what your cost boundaries are. Remember there may be an upfront cost involved here but it will save you money in the long run if you purchase the correct modem. There are several modems that you can purchase that are compatible with COX ranging from $40.00 to $250.00.

  • Internet Speed

Your new modem must support your internet speed. With COX offering plans that accommodate “Gigablast” speed, you need to make sure that the device you buy works within its parameters. If you are unsure of your current internet speed, log onto the internet and search for “The internet speed test” to run the quick and simple test for easy results.

  • Cable modems

Cable internet providers such as COX will require a coaxial cable on cable devices which means the modem will need to have a coaxial connector. You can look at the back of the modem to make sure that there are slots there allocated for such purposes.


1. What is a modem?

A device that uses the analog signal of your phone to send digital data to your computer. COX offers a variety of plans that are suitable with all the modems listed in this article.

2. What different types of modems?

Currently, there are five different models: Standard Dial-Up Modems, DSL Modems, Cable Modems, Modem/Router Combo, and Ethernet Modems. The most common is currently the cable modems that are supported on the COX networks.

3. What do I need to consider when buying a Modem?

A few important things need to be considered when buying a modem. ISP Compatibility, Speed Support, Streaming Channels, DOCSIS Protocols, Ports, Design, Security and Perks, and lastly Price and Warranty setup. For the best plan on COX, the Gigablast, you will require a DOCSIS 3.1 modem.

4. What do I need to be careful about?

You need to fact-check inaccurate speed claims made by manufacturers. COX has a section on its website where you can accurately assess the different modem speeds to make an informed decision.

5. How does a modem work?

A modems core function is to bring the internet to your home or work. Visit the COX website to inquire about their great plan offerings and their technicians will assist you with installation and operation.

6. Which modems are compatible with Cox internet connections? 

When it comes to Cox internet connections, you might just want to make use of DOCSIS 3.1 cable modems. Given that Cox is one of the biggest and the most well-known of ISPs in the US markets, there generally are no compatibility issues with practically any cable modem. You can pick up any modem that comes with a port for a coaxial cable and it is bound to work really well with Cox internet connections. 

7. How to make sure my Cox modem does not heat up? 

In order to make sure that your modem does not heat up, keep it in a place which is rather open and well ventilated. If you keep it in a cramped place, chances are that it will heat up more. Also keep your modem away from dust, or ensure that you are cleaning it regularly. Dust tends to clog all the heat vents and this often causes the modem to heat up. If you still find your modem heating up, we recommend adding a clip-on fan. In case even that doesn’t help, we recommend you to keep your modem in an air-conditioned room. 

8. Does a DOCSIS 3.1 modem provide me a faster speed? 

A DOCSIS 3.1 modem does provide you with faster speeds, but only when compared to a DOCSIS 3.0 or an older-gen modem. Your actual internet speed depends on two things – the kind of internet plan that you have with your ISP, and whether your modem/router can support those speeds. If you have a 300 Mbps plan but your modem supports only 150 Mbps speeds, you might not be able to get the best speeds. However, DOCSIS 3.1 modems can allow you to experience the full potential of your internet plan. 

9. Do all Cox modems come with built-in WiFi support?

No, not all Cox modems come with built-in WiFi routers in them. There are many modems that do not have this, and provide only wired internet access. Hence, not all cox modems come with built-in WiFi in them and you might have to buy a separate router. However, give that the range of most built-in routers isn’t that great, you’re not really losing out on much when you buy a separate router.


All things said and done, we voted the TP-Link Archer 7 the best buy. Not only does this device fit into the right price bracket but its features pack a punch. With the external antenna providing additional coverage and the dual-band capability the Archer 7 is great for home and office use. Even though this is not a stand-up model like the Motorola MG8702/MG7700, it has a classy finish and can be left on a shelf or mounted onto the wall with the brackets that come in the package.

As if this wasn’t enough to be excited about, the Archer 7 also links to Alexa which was a feature not found on any other model and has two USB ports where the Netgear CM500 did not have this ability. If you are looking for a modem to do gaming and streaming or to simply work off of and browse, the TP-Link is the perfect partner for you. Whilst the Arris SB8200 and SB6190 also had these capabilities, the TP-Link won our hearts over with its dual-band capability.

With the Gigablast plan available from COX who provides free installation, you can rest assured that your internet woes will be a thing of the past.
