Everyone requires a modem compatible with their ISP, but it also must be able to download (and upload) at the required speed as per your preference. Read More

MODEM (Modulator Demodulator) is a device that converts analogue signals to digital data. Modulator and Demodulator are the two main functions performed by a modem. That's why their name is "modem." Technically, data transmission through the Internet is accomplished by modulation, which involves the superimposition of a digital waveform onto the radio frequency (RF) signal. The process of demodulation is performed in reverse. It separates the digital data that may be used by your home network from the RF carrier wave.

A modem connects your system to the internet service provided by your ISP. On the other hand, when one modem is installed and operational, you will usually give it another thought once there's an issue. Rental modems are available from internet service providers. However, it is typically more cost-effective to purchase your high-quality modem.

Best value for money

You need a modem that is not only compatible with your ISP, but also capable of downloading and uploading at the speeds for which you are paying.

While we mostly cover DOCSIS 3.0 modems, DOCSIS 3.1 modems are also becoming available and have the potential to reach speeds exceeding of 1Gbps; if you are connected to DOCSiS 3.1 service, you should look for a device with the ability to take full advantage of such speeds.

The ARRIS SBG7400AC2 is the greatest cable modem due to its proven reliability, high performance, and affordable pricing. Those interested in future-proofing your modem can look into the ARRIS SBG7400AC2 as an option. ARRIS SBG7400AC2 is future-proof because it has a DOCSIS 3.1 modem.

Best overall

You shouldn't feel compelled to get the lowest modem available, but you should think about options that will pay for themselves in less than a year through the money you'll save on modem rental. As a bare minimum, you should expect a warranty to last for one year, and ideally, you'd have coverage for two years.

Both the ARRIS SBG7400AC2 and the NETGEAR Orbi have a sleek design and offer remarkable speeds, with potential to increase as faster internet services become available. When compared to other competitors, its speed and potential capabilities far exceed those of the industry. Always ensure that it works with your ISP so you don't waste your money. If you don't require the absolute quickest speeds, though, the NETGEAR AC1900 WiFi Modem is an excellent option at a much reasonable price.

How to find the best Modems

When buying a modem, it is essential to ensure that it is compatible with your Internet service provider. Before making a purchase, you should ensure that your Internet service provider (ISP) supports the modem brand and model you want to buy.

In most cases, this indicates that the modem has been "approved," which denotes that it has undergone testing and has been certified to function for them. Check out the hub for approved modems if you want to learn more about modems that are compatible with your Internet service provider.

You should also think about whether you want a DSL modem or a cable modem.

There is a fixed maximum internet speed that can be supported by a modem. The vast majority of individuals find that a DOCSIS provides them with all the performance they require. However, models with the most recent version of DOCSIS (version 3.1) need to be taken into consideration for customers who require increased download and streaming speeds for activities such as gaming.

The number of download and upload channels (24 x 8 or 32 x 8) that a modem can access simultaneously is referred to as its channel capacity. The greater the number of channels that it is simultaneously able to access, the speedier the service will be.

Most modems reach temperatures of 104 degrees Fahrenheit or higher while in use. To avoid potential heating problems, we searched for models with above-average ventilation.

Best modems

It may or may not work. A variety of factors influence internet speed. Maybe most importantly, you get what you paid for. A faster modem won't help if your internet speed is already 100 Mbps and you're paying for a plan that offers more than that. Look into the average lifespan of a modem to determine if replacing yours is necessary.

While most modems have an easy set-up process, your ISP's setup may vary. In certain cases, you just need to connect to a router, download and install an app from your Internet service provider, and you'll be ready to go. Changing the cables is a simple process for some. Check the modem's compatibility with your Internet service provider before making a purchase.


The lifespan of a modem is dependent not just on its quality but also on how well it is maintained and how quickly technological advancements occur. They usually last between 2 and 5 years. If your modem is outdated and your internet speed drops, it may be the modem.


DSL modems, unlike cable modems, require a dial-up connection to function. A dial-up connection is not necessary when you use a cable modem as your Internet access method. These cable modems can be set up with a wireless router to provide wireless internet access.


If you want to connect to the internet wirelessly, you need both a modem and a router. Even if the modem and router do the same thing, the primary function of a modem is to get the internet connection home safely after it has been lost. A router's task is to split a network into several different channels. If you have both, you can use your phone or tablet to connect to the internet wirelessly.
