Buying Guide for the Best Cisco Cable Modems

As the world becomes more connected and more people invest in decent home internet connections, you need to ensure that you are not only subscribed to the fastest internet service, but you also need to make sure that you have the best hardware for the high-speed, stable internet connections you seek.

For that to happen, you need a decent router and modem. The router cannot work without a modem because the modem is what allows for the conversion of internet/ cable signals from your ISP into a signal version understood by your digital devices. From the mode, the router will then take over the signals, and it beams the signals out via WiFi, allowing for wireless internet connectivity throughout your home. Now, for this to happen, you have to consider a number of features.

Below, we look at the important considerations you need to keep in mind in your search for the best Cisco cable modems.

Types of Cable Modems

The cable modems are either standard/ standalone or modem-router combos.

The standalone standard modem is the best modem option, and if this is the first time you are looking for a cable modem, we’d recommend the cable modem. The main reason for this is that when a new wireless technology comes along, as it always does, having a standalone modem and router will allow you to easily replace one of the devices at a time. You also get to enjoy a lot of flexibility with standalone modem and router because the standalone devices often come with more features and even configuration options, compared to the combination devices.

The only downside of buying the modem and the router separately is that they might cost a little more than you’d bargained for, and there’s also the matter of setup plus the cables. Two internet devices leave you with more wires to deal with and untidy setups. These factors notwithstanding, the performance of standalone devices is unmatched.

The modem-router combination, on the other hand, refers to a 2-in-1 device that features the modem and the router. Such combination devices will allow you to plug in the devices without having to reset or tweak its settings, especially if you don’t anticipate the need for further changes in the future. Over the years, the combination devices have grown in popularity, and they work quite well straight with their factory settings. The only issue is that of future technologies and the fact that you’d have to replace both pieces of equipment to enjoy advanced wireless technologies.

DOCSIS Protocols

When it comes down to the search for the best cable modem, you need to remember that the best modems will only deliver the desired lightning-fast speed if it features some of the most advanced technologies. Generally, the maximum speed offered by the cable modem selected, will depend on the Data Over Cable Service Interface Specification, better known as DOCSIS protocol.

Essentially, the DOCSIS protocol represents the standard through which all modems are capable of transmitting internet signals via cable. The newest version of the DOCSIS protocol is DOCSIS 3.1, and this standard promises high internet speeds of up to 10Gbps. But if you don’t necessarily need such high internet speeds, you could opt for the modems that run on the DOCSIS 3.0 standard. Although this modem isn’t as fast as the DOCSIS 3.1 protocol modem, the speeds are pretty high, and you still enjoy cool speeds of up to 1Gps – this is good enough for most internet users.

But there’s a catch; while the ISPs promise to offer high internet speeds to match what is promised by the modem manufacturers, the truth is that very few ISPs are capable of offering high 1Gbps internet speeds, especially over DOCSIS 3.0 systems, and in most cases, you will have to buy a DOCSIS 3.1 modem to be able to enjoy internet speeds above 630Mbps. The good news is that the DOCSIS 3.1 modems are backward compatible, which means that these modems would support DOCSIS 3.0 ISPs, and you won’t have to worry about replacing the modem too soon.

Note that if your ISP doesn’t support DOCSIS 3.1 system, you might want to invest in a modem that supports this wireless system. Even if you feel that you won’t need that technology today, you will need it later on. So, even though investing in modems that run on the newer standards is often expensive, it often turns out to be a worthy purchase.

That said, avoid modems that only support the DOCSIS 2.x or DOCSIS 1.x protocols – they aren’t secure and also very slow.


Also called channel bonding. This is the other factor that you need to look out for in your cable modem because it will affect the internet speeds offered by your modem.

Modem channels are specified as download and upload channels expressed as numbers ‘x’ by the other number (download x upload channels). In this case, a 32×6 modem has 32 download channels and eight upload channels.

When choosing a modem, you will find that the DOCSIS number comes before the channels number. For DOCSIS 3.0 modems, the download speeds reach 43Mbps on each of the channels – hence download speeds of 688Mbps on a 16×4 modem, and subsequently 172Mbps for the 4 channels in upload speeds. The speeds on the DOCSIS 3.1 modem, on the other hand, will be higher, and it’s projected that each downstream channel would offer impressive high speeds of up to 1.89Gbps and upstream channels offer speeds of up to 0.94Gbps.

But these are only theoretical speeds, and the actual internet speeds enjoyed will depend on the ISP’s speeds. So, if you are subscribed to an ISP offering a maximum speed of 100Mbps, that is the maximum internet speed you will enjoy from your modem.

Upload and Download Speeds

Even with the specifications for the DOCSIS standard and the number of channels, modem companies will still specify the modem’s upload and download speeds. A modem that supports speeds of up to 1Gbps is a good option if you need fast internet and if you anticipate rolling out of fast internet speeds by your ISP. However, it’s important to keep in mind that the average internet download speeds you will enjoy will be about 64.17Mbps.

Ethernet ports

The only way for your modem to communicate with your router and the rest of the devices in your home is via the Ethernet port, which is why you need to invest in a modem with at least one Ethernet port that will connect to your router.

Once plugged in, the router will beam out your WiFi signals. Since you are getting the best router with at least four Ethernet ports, you will be able to enjoy wired connections to your computer and smart home hubs, among other devices.

However, if you don’t mind splurging on a modem, you might like the newer DOCSIS 3.1 modems that feature two Ethernet ports. The extra Ethernet port is designed to support a new wired internet feature, the link aggregation 802.3ad system. While Ethernet ports are designed to support Gigabit speeds, the new link aggregation feature allows you to connect two Ethernet cables to the modem (between modem and router), allowing you to enjoy a maximum combined throughput of 2Gbps. But you only get to enjoy the high speeds from the 802.3ad standard if your ISP plan exceeds 1Gbps.

ISP compatibility

Double-check with your ISP before you buy a modem. Some modems are only compatible with specific ISPs. Before you buy the modem, check the ISP website for the list of compatible modems.

Lastly, you need to consider the design. You need something that won’t take up too much space but look good. However, you should never compromise design for speed or performance.


When do I need to replace my modem?

Essentially, you will need a new modem if your older one isn’t working well if you don’t wish to pay modem rental fees anymore, and if you need an upgrade to a modem running on the latest technologies, for example, a DOCSIS 3.1 modem.

Should you buy a standalone cable modem and a router or the combo?

Well, the decision to buy a standalone modem and router over the combo device will depend on many factors, including your budget, but if you aren’t worried about technological changes in the future, and you are tired of different setups and configurations, along with the cables that come with two internet devices, the combo might be a good option for you. Just keep in mind that an issue with the combo will mean the replacement of two gadgets rather than one.

How does the Cisco cable modem HWICs work?

The Cisco cable modem High-Speed WAN Interface Cards work by allowing your router to communicate over the HSD/ High-speed data cable network for your office-to-internet/ branch-to-branch connectivity.


The modems above are among the best Cisco cable modems on the market. While Cisco cables are largely DOCSIS 3.0 standard modems, they are still fast and reliable. Just make sure that you buy a modem that’s compatible with your ISP.
