Subscribing to internet service through a cable provider can entail a whole new set of fees in addition to your base subscription price. Most notably, there are rental fees for the cable modem and router that can add $100 or more per year to your cable bill. Over the service life of this equipment, a cable subscriber could shell out hundreds of dollars. What’s more, the modem and router often aren’t the latest models, so not only are they prone to breaking down sooner than expected, they may not be able to properly handle a high-speed internet connection.
There’s a solution to this dilemma. Getting a cable-modem router combo, also known as a gateway, gives you control over the quality of your internet and cable connections and eliminates one or more rental fees from your cable bill. What’s not to like?
A cable modem-router combo is a highly efficient setup. It receives a data signal from the cable provider via a coaxial cable running from a nearby network node to the device. That data signal is processed by the cable modem and delivered wirelessly throughout the house via its onboard WiFi transmitter. It’s important, before making a purchase, to make sure a particular gateway would deliver optimum performance for your particular internet setup.
That screamingly fast cable modem-router combo at the top of the price range may not be the right device for your needs. It must be compatible with the service and internet speed your cable company delivers. For example, if you have a 50Mbps (megabits per second) internet connection, a gateway designed to handle 1Gbps (gigabits per second) is overkill. And if the cable company doesn’t support the gateway, it won’t work at all.
Internet speeds continue to rise, and the WiFi spectrum is evolving, too. A cable modem-router combo must be compatible with new technologies for at least a few years after its purchase.
Most gateways advertise fast download speeds (the speed at which you receive data, such as streaming video) but downplay upload speeds (the speed at which you send data, like uploading photos to Facebook). Upload speeds are typically much slower than download speeds.
One downside to the cable modem-router combo is that putting both a modem and a router into a single device limits some of your options. For example, if the router becomes obsolete or can’t be upgraded through a software update, you may need to replace the entire combo. Also, combo routers tend to have fewer features than standalone routers.
The tradeoff for fewer features and options is a single device that takes up less space, is easy to set up, and will run reliably for quite some time.
A cable-modem router combo can cost a lot more than a separate router or a separate modem. See our Cable Modem-Router Combo Prices section for more in-depth information on costs.
On the surface, a cable modem-router combo seems to have just a few features: randomly blinking lights, a smooth outer shell, and perhaps a couple of Ethernet ports. Of course, much more is going on inside the unit.
Modem: This part of the combo receives the signal from the internet service provider and can connect that signal to just one device.
Router: Connecting to multiple devices, both wirelessly and through an Ethernet port connection, is accomplished by the router.
Multiple ports: Cable modem-router combos typically have at least four Ethernet ports, giving users the option of a direct-wired Ethernet connection to the internet.
Multiple WiFi connections: Users with a WiFi-enabled device and the gateway password can access the internet from anywhere in the home.
Guest account: Gateways increasingly include a guest WiFi account that can be protected with a separate password, left open for use with no password (not recommended), or disabled by the owner.
Downstream channels: Look for a combo with at least 16 downstream channels to handle faster internet speeds.
Upstream channels: There will always be fewer upstream than downstream channels. For example, there may be 24 x 8 — 24 downstream and 8 upstream channels.
Low-end cable modem-router combos start as low as $63 and range up to about $105, though they may not have the performance you need. For just a bit more, starting around $120 and moving up to $190, you can get a reliable device with a range of features that are compatible with most cable companies’ DOCSIS standards.
For peak performance in the gigabit-plus speed range and compatibility with fiber-optic internet providers, cable-modem router combos start around $250 and go as high as $350.
Q. How do I find out if the cable modem-router combo I want to buy would work with my current internet service?
A. Check your cable company or internet service provider’s website for a list of compatible devices, or call or chat with their customer service department directly. Some independent websites can also provide information on which gateways are supported by your internet provider.
Q. If I buy a super-fast cable modem-router combo, will my internet speed be faster?
A. The speed of your internet service is determined by two big factors: the internet plan you subscribe to and the limits of the cable company’s network. Traditional cable companies overwhelmingly use the DOCSIS delivery protocol. While this delivery method is pretty close to miraculous, it’s still much slower than fiber optic cable-based networks. If your internet service is capped at 50Mbps, for example, buying a gateway that delivers gigabit speeds wouldn’t make your service any faster than 50Mbps.
The main reason to buy a faster gateway is to future-proof it against major speed upgrades from your provider in the next few years. Call your provider (or check the news) to find out if a speed upgrade is planned. If so, buy a gateway that matches that planned speed. If no speed upgrades are planned, save your money.
Q. I see a number figure, 8 x 4, in the description of the cable-modem router combo I’m considering. What does that mean?
A. That number figure, or similar figures like 32 x 8, describe the number of downstream channels vs. upstream channels the modem has. Almost all modems have more downstream than upstream channels. This is a good thing, especially if you’re planning to stream video or play online games. A cable modem-router combo today needs at least 16 downstream channels to handle high-speed internet.
