Best Cable Modem Reviews 2018

When it comes to shopping for modems, there are typically two reasons people need one: they have existing internet that is connected directly to a single computer and they want internet for other computers or devices (which requires a Wi-Fi/Wireless Modem) or they don’t want to rent or use the one that has been provided by their internet service provider. For the purpose of this review, we are focusing on the second option. We have done extensive research and come up with a short list of five of the best cable modem brands, featuring a great Ethernet modem from each one. We hope that you will find a product that rings true to you from those featured below. If it turns out you were looking for a Wi-FI modem, we have a review for those too.

How Do I Choose the Best Cable Modem?

The internet is arguably man’s greatest invention since Thomas Edison’s incandescent electric bulb. It is virtually impossible to lead a productive life today without unfettered access to the internet. From shopping on Amazon to watching movies on your computer, to booking an appointment online, the internet has made life simple.

However, you cannot enjoy these benefits without first establishing access to the Internet, and not just any access, but a steady and robust one. You don’t want a simple search on Google to take you 5 minutes or for your favorite online shop to load in 10 minutes. Assuming your ISP has enough bandwidth to distribute to its customers, the kind of internet modem you have will go a long way to determine how good your internet experience will be.

Modems enable you to access the internet and they can be Ethernet cable modems or Wi-Fi Modems. A Wi-Fi modem bypasses telephone systems and connects directly to a wireless network. Through this, it directly accesses the internet provided by your ISP and can be used to connect multiple devices without the use of wires and cables. Note that for your desktop computer or device to be able to access the internet wirelessly, it must have a wireless network card. Most computers these days, especially laptops and tablets have this by default. A cable modem, on the other hand, permits your computer to communicate with an ISP over a landline connection. It does this by converting an analog signal to a digital signal in order to grant you access to broadband internet.

You might discover that although you have access to the internet in your workplace or home, some people in certain locations are unable to access it at all or they have a poor connection. In this case, you may also need a Wi-Fi extender. Wi-Fi extenders enable internet service to get to places that are ordinarily outside the coverage of your LAN.

Now that we understand the two types of modems, let’s turn our attention to some specific things you should look for when shopping for the best Ethernet modem for your location. If you were looking for a wireless modem, you may want to check out our Wi-Fi Modem buying guide.

Price

The type of cable modem you buy and its price is determined by a few factors. While it’s important that you don’t exceed your budget, you should also ensure you buy what you really need. Yes, you can find lots of cheap cable modems out there however in many cases this means sacrificing quality not only of the physical product, but of the connection too. We came across many of these during our research but didn’t add them to our top five reviews because we want to present to you only products and brands that offer you value for money (along with durability and peace of mind).

That said; here are a number of things that affect a cable modem’s price: The speed of download from or upload to the internet, how many ports it has, the warranty on it, its Wi-Fi capability and the brand you are buying from.

Products from popular brands tend to cost more even if they offer similar value with less popular brands. But as a general observation, the prices of very functional and versatile cable modems range from $60 to about $110 and the greatest determinants of price are the warranty and the brand of the modem. Apart from these, most of them have basically the same specs. For the products we have reviewed, you will be making a great a buy irrespective of whichever you go with

Features

Buying the right modem can be a herculean task but once you know the key features to look out for, then your selection process becomes a bit easier. These features determine, to a great extent, the kind of internet experience you will have with your modem.

You will want to pay attention to things such as:

Compatibility with major ISP cable providers
Broad router compatibility
High-speed Internet connectivity
IPv4 and IPv6 dual stack support
Upload and download speeds
Modulation
Frequency range (downstream)
Easy plug-and-play setup

Construction and Design

Good cable modems (and indeed all high quality modems) are built to be strong. You don’t want a modem that breaks or shatters just falling once. So, ensure that the modem you want to buy is made from high quality materials. Also, you need to ensure that the heat output is minimal, especially if you are using it in a non-air conditioned place for prolonged periods.

There are some modem brands that come in different colors - predominantly black or white. This may be an important consideration if you are not the only one who has access to this modem. Too many hands touching the modem could make a white colored modem dirty in no time. In this case, consider buying a black or dark colored cable modem to save you the stress of always cleaning the modem.

Performance and Ease of Use

Modems should be easy to install and use in any laptop or desktop computer. So, its plug and play feature is key in determining which modem to go for. For the ultimate in simplicity, the modem choose for shouldn’t require a CD for installation. It should be plug and play.

Ensure also that the download and upload speeds really meet your needs depending on the kind of activity you carry out on the internet. If you all you do is check your emails and do some Google searches, you will do just fine with just about any download/upload speed (but we really doubt this is the case or else you wouldn’t be on this page). Heavy video streaming, gaming and using online apps demand that you pay serious attention to your download and upload speeds; the higher, the better.

Some modems come with stands and some don’t. If a modem comes with a stand, then you have more placement options. A good modem should be easily placed wherever you want it, especially if internet reception is better at one location than the other.

If you’re on a budget and need to move a single modem from one place to the other then portability will be a serious consideration when choosing the best Ethernet modem for your needs. If you use the same modem between work and home, then you don’t want moving the modem to be a hard task. Again, this is where a modem with plug and play features make a lot of sense, or you might decide to go with a Wi-Fi modem so you don’t have to keep undoing and re-connecting the cables.
