Best Modem

Article Contents

Modems are one of the most important computer devices when it comes to setting up a network connected to the Internet. The modem connects directly to an incoming Internet signal, provided by your Internet Service Provider (ISP), and then relays that signal to other devices. There are quite a few different types of modems out there, based on the type of Internet signal you receive and the setting for your network.

Cable and DSL modems are used for high-speed internet, replacing older dial-up modems that established an Internet connection through a phone line. Satellite modems work in a similar way, communicating with a satellite relay to receive and send signals. In-car Internet modems are interesting devices, used to receive a signal in a vehicle so that you can connect to the Internet while on the road. With so many options and devices available, take a look at the modem buyer’s guide below for more information on picking the right model for your setup.

Best Cable Modem:

In looking at cable modems, there are a few major concerns to keep in mind. Look at the speeds that various modems support, though your actual internet service will largely determine your data rates. Reliability is a big issue, since you want a modem that is going to last you awhile, check the different manufacturers and look at user reviews to see where people have problems and how the manufacturers dealt with those issues. The number and types of connections on these modems is also important to be sure they can easily connect to other devices. As technology improves, it is also worthwhile to make sure you pick a model that offers some future-proofing through support for the latest standards.

These cable modems were chosen because they run fast with support for at least 131MB upstream and 172MB downstream speeds. Such fast data rates are possible thanks to at least four download channels and four upload channels with each of these modems. You get support for DOCSIS 3.0 as well as IPv4 and IPv6 standards with these modems, making them ideal for all modern networks and a wide range of cable Internet Service Providers.

                      Best In-Car Internet Modem:

                      While there are a number of ways to create networks for internet connections in remote locations, in-car devices are actually fairly rare. Many modern mobile phones, for example, can be used to create a hotspot that other devices can then connect to for internet access. However, the problem is that such connections in a vehicle moving quickly along a highway (often passing between signal zones) can easily be lost or interrupted. In-car internet modems are installed into vehicles and designed to maintain a strong mobile connection even while on the move. These devices are usually quite expensive and specialized, meant for more than just occasional use while sitting in a parked car while waiting for a friend.

                      We've chosen these as the best in-car modems thanks to their support for at least 3G mobile connectivity, which provides fast and reliable internet service in a vehicle.

                          Modem Buyer’s Guide

                          Despite the importance of a good modem when setting up a network, there are only a few major concerns you need to look at when picking the right device for your system. Consider the different types available and pick one that is right for the type of Internet signal you have, and also be sure that it is compatible with your particular ISP.

                          Look at the interface connection used by each modem to ensure you pick one that works with your computer or other hardware, and consider any additional features you need. The transmission rate is the most important technical feature when looking at modems, as it directly impacts how quickly you can send and receive data, so be sure to pick the fastest option you can.

                          Types of Modems

                          The type of modem usually refers to the kind of Internet signal it is designed to receive, based on the type of ISP you use. One major exception to this is an in-car modem, which is designed to receive a signal while in a vehicle.

                          Dial-Up Modem
                          These are older devices used to connect to the Internet over a telephone line. Unless you are in a very rare and specific circumstance where you only have access to dial-up Internet, there is no reason to choose this type of modem.

                          Cable Modem
                          Used to connect to a cable Internet service, this is one of the fastest options on the market. If you have cable Internet, then this is the modem to choose, and just be sure to pick one that is fast enough and compatible with your specific ISP.

                          DSL Modem
                          Digital Subscriber Line or DSL uses traditional telephone lines to deliver high-speed Internet access. If you have a DSL signal, then choose this type of modem, but be sure that it works with your ISP.

                          Satellite Modem
                          A satellite modem receives a wireless Internet signal from a satellite, providing you with a connection just about anywhere. These are specialty devices that you really do not need to worry about unless you already have satellite Internet from a provider.

                          In-Car Modem
                          This is another specialty item that turns your vehicle into an Internet hotspot. While many modern mobile phones can act as wireless hotspots, using one in a moving vehicle can be difficult as you transfer from one signal area to the next. In-car modems ensure consistent coverage and signal strength no matter where you go.

                          Gateway Modem
                          A gateway modem receives and sends signals along the Internet just like other modems, but also creates a Local Area Network (LAN). This is typically used in a residential household or small office if you want to connect to the Internet and create a small local network all with a single device. If you plan on using a separate router, however, then you probably do not need a gateway modem.

                          Interface

                          The interface refers to the connections available on a modem, which you then use to connect a router, computer, or other hardware to it. Most modems have one input connection that you use to connect to the source of your Internet signal, either a phone line or cable input. From there, you get at least one interface output connection, which you use to connect your modem to other hardware. This is usually an Ethernet or Cat-5 cable that connects to a port on your router, computer, or other device.

                          Some models can include a PCI or PCIe connection or even a USB port for connecting other devices. Choose a modem based on the connections you have on your computer or router to make sure you can easily plug your modem into your other hardware.

                          Maximum Data Rate

                          The data rate indicates the speed at which data is received and sent by the modem. This is important because the actual rate is determined by your ISP, based on the data rates they set, but your modem can bottleneck performance. If your modem only supports speeds that are slower than what your ISP provides, then you won’t be able to take advantage of the fast Internet you pay for.

                          You want to look at both upstream and downstream rates. Upstream indicates how fast you can send data, while downstream shows how fast you can receive it. Downstream (or received rate) is usually much faster than upstream. For high-speed Internet, you want a modem with down rates of about 300Mbps or more and up rates of 100Mbps or more.

                          ISP Compatibility

                          This can be easy to overlook, but it is very important to make sure that you choose a modem that is compatible with your ISP. Make sure you know what type of Internet you have, usually either cable or DSL, as well as the name of your ISP.

                          With that in mind, look at any modem you might be interested in and make sure it specifically works with your ISP, whether you have Cox, Time Warner, or another company. If you really want to be sure, contact your ISP and ask them if the specific modem model you plan on using is compatible with their service.

                          Additional Networking Features

                          While compatibility and data rates might be your biggest priority, there are some extra features that you should consider. Look for security and encryption features as you compare different modems, though mostly you want to be sure that any network security you plan on using will work with your chosen modem.

                          If you don’t already have a wireless router, then consider a gateway modem that provides you with a local wireless network as well as connecting to your Internet service. Finally, look for models that include some future-proofing thanks to support for the latest standards such as IPv6.

                          Manufacturer and Warranty

                          While the names of manufacturers of modems might not be familiar in every household the way that computer builders are, it’s still important to choose a company that provides reliable hardware in their builds. Manufacturers like D-Link, Netgear, and ARRIS produce good modems that work well and run nice and fast. While you can usually rent a modem from your ISP, buying one typically saves you money in the long run, but only if it lasts you a few years. A one-year warranty is the bare minimum you should look for, while two or three-year warranties are preferable.
