With these, you will get a faster connection as promised by your service provider. Cox offers you a wide range of internet packages through bundle services, hence you can always choose which one best suits your budget plans. Here are some of the best modem for cox you might want to consider:
1. ARRIS SURFboard DOCSIS 3.0 Cable Modem (SB6121)
The ARRIS SURFboard SB6121 DOCSIS 3.0 Cable Modem is a wired modem and does not come with Wi-Fi router or an adapter for VoIP Telephone. It has an Ethernet Port that allows you to connect to a computer for faster downloads. Its speed is highly dependent on the cable provider service.
When properly connected can give you the download speed of up to 172 Mbps and 131 Mbps upload speed. With such amazing speed, you can enjoy your video games or live to stream without losing connection.
This modem is compatible with Cox, Comcast, Bright House Networks and Time Warner service providers. It may however not work well with Verizon FiOS and At&TU versions.
Before you use it, however, call your service provider to confirm if your device is compatible with cable internet service as this is what the SB6121 DOCSIS 3.0 Cable Modem is powered on.
- DOCSIS 3.0 for great up- and downstream transfer rates.
- IPv6 support.
- ASUSWRT graphical user interface.
- Compatible with Cox, Comcast, Bright House and Time Warner.
2. ARRIS SURFboard SBG6580-2 DOCSIS 3.0 Cable Modem
This modem is designed to give you value for your money. It comes in a 3-in-1 package that contains a cable modem, 4 Port Gigabit Router, and N600 Dual-band Wi-Fi connectivity.
The modem is cable internet service enabled and has been approved for use with Cox, Time Warner, Xfinity, Comcast, Mediacom and Bright House Networks, among other Cable Internet Providers who have plans not less than 100 Mbps. Networks such as Centurylink and Verizon will not work very well with this modem.
The package comes with N600 WiFi Router and has 4 Gigabit Ethernet Ports. You are warned to be vigilant not to be conned with the Brown Box models of this modem as they are no longer valid.
- Twice as fast as the SB6121 version at the same price.
- Doubles as a router.
- DOCSIS 3.0 and IPv6 support.
- Most regional cable providers with plans 100Mbps and up are supported.
Whilst our main criticism of the similar-looking SB6121 was the lack of any non-standard features, we just can’t get enough of the SBG6580’s long list of extras.
From a fully integrated wireless router to twice the speed of its sister model, this represents the definitive SURFboard model to buy.The catch? We haven’t been able to find one.
Even the price tag, at $105, is almost identical to the SB6121 model, making the SGB6580 not just one of the best, but also one of the most cost-efficient ‘all-in-one’ modem/router combo devices around. Which makes us wonder why the SBG’s inferior little brother is still even sold.
3. Cisco DPC3010 DOCSIS 3.0 8×4 Cable Modem
The Cisco DPC3010 DOCSIS 3.0 8×4 Cable Modem has been tested and found to be compatible with most cable internet providers like Suddenlink, Comcast, WOW, Cox and Charter among other providers.
In comparison with other modems, its speed is relatively faster if the connection from the cable provider is at its peak. You can enjoy download speeds in excess of 320 Mbps and upload speed of 120 Mbps.
This speed is up to eight times faster than what is available from single-channel DOCSIS 2.0 modems that are cable enabled. It is designed to work best with DOCSIS 3.0 models, offering you high-speed connectivity.
A newer version of the Cisco DPC3010 DOCSIS 3.0 8×4 Cable Modem is the Linksys High-Speed DOCSIS 3.0 Cable modem. It has been approved for use with providers like Warner, Charter, Cox, Comcast, and Xfinity.
If you are looking for a cost-effective solution to internet connectivity, look no further as this is the model that will best suit you.
- DOCSIS 3.0 capability.
- Highly affordable.
- Compact, space-saving design.
- Large list of supported ISPs.
- 8 Download and 4 Upload channels.
Whilst the previously looked at SURFboard represented a medium- to high-end modem equipped with lots of handy extras, the Cisco DPC3010 is something totally different: An affordable, effective and compact budget machine.
Sorry, no built-in router on this one, folks!However, what you do get is very exciting given the ultra-low price of just $60: DOCSIS 3.0, the same speed and channels as in the more expensive SURFboard, a clean-cut, space-saving exterior and probably the best ISP support in the industry with almost every noteworthy provider and their plans being compatible with the DPC3010.
All in all: The best ‘bang for your buck’ modem currently on the market.
4. Linksys DOCSIS 3.0 16×4 Cable Modem (CM3016)
Although this modem does not come with telephone and voice ports, the service you will get from its connectivity is all reason to consider buying it for use with your Cox enabled device. The Linksys DOCSIS 3.0 16×4 Cable Modem (CM3016) gives you the luxury of high-speed connectivity, boosting your already existing ISP plans.
Download speeds can be as good as 250 Mbps, which make the modem ideal for web surfing, media streaming, and online gaming. The modem can withstand high bandwidth transfer rates, with minimal loss of connectivity.
This is enhanced by the Intel Puma 6 feature that serves to increase both download and upload speed performance. Most of the major cable internet providers have approved the use of this model.
- Exceptionally high speed thanks to 16 Download channels and 4 Upload channels.
- Simple and easy-to-use.
- Price-to-performance ratio is excellent.
The Linksys CM3016 is by far the fastest modem on our list, offering download speeds exactly twice as fast as the ARRIS SURFboard in its SBG6580 variant.
This, unfortunately, is also its greatest flaw: The modem’s whole appeal is wasted on the download speeds, so much so that it doesn’t really offer anything besides raw, largely meaningless power.
The list of supported ISPs is rather short, there is no integrated WiFi-router, no VoIP, no telephone connection option and there isn’t even proper IPv6 support.So, if you’re looking for the fastest modem around, look no further, as, for merely $85, you are bound to be impressed by the CM3016.
However, if you would like a more well-rounded device and gladly sacrifice raw power for a better overall user experience, then look elsewhere.
5.Zoom 343 Mbps DOCSIS 3.0 8X4 Cable Modem (Model 5341J)
If you are looking for fast yet cost-effective internet connection, do not search any longer as the solution lies with Zoom 343 Mbps DOCSIS 3.0 8X4 Cable Modem (Model 5341J). Among the best top 5 modems, it is the only one with internet speed of over 325 Mbps downstream and over 140 Mbps upstream.
The fast Ethernet port can be connected to Home Plug adapter, router, wireless access point, Windows or Macintosh computers. It only functions as a modem and supports all DOCSIS cable modem standards.
One special feature of this modem is that it comes with advanced networking capability of IPv4/6 for flexible and powerful network addressing.
The package comes with Ethernet Cable, energy saving power cube that can be switched on and off and also with a modem stand. It has been approved for use with all major network providers.
- Compact and minimalist styling.
- 8×4 channel setup promises great speeds.
- DOCSIS 3.0 and IPv6 support.
- Can be used horizontally or vertically.
- Above average ISP support.
The Zoom 5341J is almost identical in its specs to the aforementioned Cisco DPC3010. It is in fact so similar that we have trouble recommending it over its much cheaper competitor.
At $150, the Zoom is the most expensive model on our list, trumping even the fully-equipped SURFboard SBG6580, but doesn’t offer any special features that come even close to the ARRIS model’s ‘all-in-one’ repertoire of extras.
Although the Zoom’s performance is highly satisfying, we can only recommend it as a last-resort alternative to the Cisco DPC3010, as the practical difference between the two is negligible, whilst the price, on the other hand, presents itself as one of the Zoom’s greatest flaws.
What to Look for Before Choosing a Modem for Cox Network.
When you buy a modem to enhance the use of Cox network, there are factors which you should consider so that you do not end up in a worse situation than you initially were without the modem. The most crucial factors to look into are.
- Technology: All network providers strive to upgrade to new versions of both hardware and software responsible for the provision of internet connectivity.Always remember that the quality of connectivity, as well as the speed of your internet, rely on the DOCSIS version of your equipment. The industry is currently at DOCSIS 3.0 and if you have an older version modem, you can upgrade it to newer versions.
- Modem Compatibility: Not every modem you buy will be compatible with Cox. If you are not sure about the compatibility of a modem with your ISP, you can always call the service provider to find out before committing your money to buying the modem.
- Purchase Options: Where you purchase your modem from also should be a matter of consideration. Sometimes due to financial constraints, the idea of buying a modem from a yard sale or from another person may seem ideal.Keep in mind that old, used modems may be faulty and could give you a hard time connecting. If previously associated with an existing Cox account, you may not be able to use them.Always strive to invest in equipment that will give you the comfort and convenience you are looking for. Remember that a new device also comes with a warranty, which protects you from losses in case it fails to perform as expected.
The Better Option for Internet Connection Between Renting And Buying a Modem
A modem is a necessity when it comes to the access to cable Internet service. There’re two options to consider in the acquisition of a modem; renting or buying one. However, it is beyond doubt that purchasing a modem is a better choice as compared renting. Let’s see some reasons behind that position.
- Long-run cost-effectiveness: IIf you have a rental modem from your internet service provider, you’ll realize that the ISP bills you certain amount of money in the form of modem rental fee.For instance, Comcast charges $10 every month to each user who rents their modem. On the other hand, you can buy a modem that’s compatible with your ISP at a pocket-friendly price, say $50, and forgo the monthly charges.The money that you would have otherwise used to rent a modem for five months is sufficient to get your own modem.
- Cost certainty: Modem rental fees keep on changing depending on the decisions of internet service providers. However, when you buy a modem, you are certain that you won’t incur any other cost in addition to the acquisition cost.
- Maximizing the value of internet services: Some rental modems may have a negative influence on internet connectivity. The issue can be disappointing, considering that you’ll eventually pay for modem rental fees. On the other hand, buying a modem that is most compatible with your ISP will help you avoid such problems.
- Easy to switch ISPs: A rental modem limits you to a specific internet service provider. However, with your own cable modem, you can switch from one provider to another as long as it is compatible them.
Another internet connection option: Purchasing a cable modem/router combo
The advancement in technology has appreciated the importance of having a modem and a router as a single unit. A combination of the two devices offers you the convenience of getting router and modem services from one box.
One thing that you’ll certainly like about this integrated component is its easier setup besides less clutter as well as fewer wires as compared to having them as separate devices.
Nevertheless, considering that nothing is perfect, one of the drawbacks of this set is that you’ll have to buy a new router and a modem in case you want a better performing router. The upgrade is more costly and complex than upgrading an independent router.
- Cox is one of the largest ISPs in the US, but sometimes there are factors that affect the speed and quality of connections. As highlighted in the article, when buying a modem to solve connectivity issues, give a thought to the make and model of the device, its reliability and efficiency which you can find in customer reviews and most importantly, ensure that it is compliant with the DOCSIS 3.0 technology. We at Cox continue to be at your service.
