But if you have broadband internet in your home — and if you’re reading this, there’s a good chance you do — then you owe it to yourself to learn the basics. Not only will you feel more confident, but it could lead to tweaks that boost your internet speed.

And in some cases, it could even relieve you of the need to rent from your ISP What's the Best Router for Ending Rental Fees? What's the Best Router for Ending Rental Fees? Internet providers don't win ethics awards. Just the opposite – they perennially rank among the least liked companies in the United States. Stop paying them rental fees! Here are the best modem-routers around! Read More , thus saving you a lot of money in the long run. In this article, we’ll walk you through the fundamental differences and what to look for if you want to improve your home network.

Modem, Wi-Fi Router, or Router-Modems

A modem translates data into electrical signals. The signals travel through cables to your house (or through the air in the case of satellite internet), and a modem is required to decode those signals back into digital data.

A router is like a mail sorter. If you think of every bit of incoming data as a piece of mail, then the router determines where each piece of mail goes — whether to your computer, your tablet, or your smart TV. Or in other words, a router lets multiple devices use a single internet connection (which is provided by the modem).

Note that even though the primary function is to serve one internet connection to multiple devices, there are several reasons why you should still use a router even if you only have one PC Why You Should Use a Router Even With Only One PC Why You Should Use a Router Even With Only One PC Every household with internet access should be using a router, even if there's only one PC connected to the network. Here are a few compelling reasons why. Read More , such as for wireless connectivity.

And then there’s a third class of home networking device that’s a hybrid of the two: the router-modem. This isn’t an official term, but it aptly describes what the device does: it translates incoming data AND routes that data to the proper devices.

Router vs. Modem: Does It Matter?

When you sign up with an ISP, they MUST give you a modem at least — this is required to establish a connection to the service. However, these days, most ISPs provide router-modems.

If you see more than one (usually about five), it’s a router-modem.

So, should you buy a router, modem, or both? The answer is always both — either as separate devices or as a single router-modem device. (Router-modems are more convenient, but if they break, you lose both modem and router functionality.)

3 Important Router Features to Check

Buying a modem is surprisingly straightforward 4 Things to Seriously Consider When Purchasing a New Cable Modem 4 Things to Seriously Consider When Purchasing a New Cable Modem With just a bit of research, you can buy your own modem and save hundreds of dollars over a few years. Read More . Make sure it’s compatible with your ISP. (AT&T’s ADSL U-verse service works with surprisingly few modems.) If you subscribe to cable internet, make sure it supports DOCSIS 3.0. Finally, make sure it’s fast enough to help your internet Mbps speed. Good ones cost somewhere around $50, and you should never need to exceed $100.

As for routers, they’re a bit more complicated (but not so much that they should scare you). There are a few basic questions you should ask yourself 8 Key Questions You Must Ask When Buying A New Wireless Router 8 Key Questions You Must Ask When Buying A New Wireless Router Here are eight questions you should ask when buying a new wireless router. Read More , but if you’re in a rush, the three features listed below are the most important considerations to make.

1. Wireless 802.11ac

IEEE 802.11ac is the latest and greatest wireless standard that was approved back in 2014. It includes a lot of improvements (particularly to data transfer speeds) and additional features (such as beamforming) that make it worth the hike in price.

Backward compatibility was a big issue when it first debuted, meaning a lot of devices didn’t support 802.11ac connections, but now that a few years have passed, that’s not much of an issue anymore. These days, there’s no reason not to get an 802.11ac router Should You Buy A Wireless 802.11ac Router? Should You Buy A Wireless 802.11ac Router? 802.11ac promises blistering speeds, but many consumers are just now getting around to upgrading to 802.11n, leaving many to wonder if the new version is worthwhile.

2. Dual-Band or Tri-Band

A dual-band router can broadcast on two frequencies: 2.4 GHz and 5.0 GHz. This is important because if there are too many wireless connections traveling on the same band, they can interfere and cause congestion (i.e. slower internet speeds). The 5.0 GHz band comes in handy as a way to bypass any congestion on the more-widely-used 2.4 GHz band — or vice versa — which can significantly improve your wireless connection quality How Dual-Band Routers Can Solve Your Wireless Woes How Dual-Band Routers Can Solve Your Wireless Woes Using a router that supports the dual-band standard can significantly boost your Wi-Fi speeds in many circumstances. Read More .

A tri-band router is similar to a dual-band router except that it has one 2.4 GHz band and two 5.0 GHz bands. As we explained in our analysis of how useful tri-band routers can be How Dual-Band Routers Can Solve Your Wireless Woes How Dual-Band Routers Can Solve Your Wireless Woes Using a router that supports the dual-band standard can significantly boost your Wi-Fi speeds in many circumstances. Read More , this third band is like having an extra lane on a traffic-congested highway — it won’t raise the speed limit, but it will reduce the likelihood of congestion.

3. Guest Access

If you’re the kind of person who frequently invites friends over, hosts dinner parties and group events, offers up your home for family get-togethers, and things of a social nature, then you’ll seriously want a router with a guest access feature.

In fact, we consider it to be one of the most crucial elements 10 Crucial Features to Use in Your Wireless Router Setup at Home 10 Crucial Features to Use in Your Wireless Router Setup at Home Most wireless routers are equipped with a handful of amazing features that you probably aren't taking advantage of. Here are some of the more useful ones to start exploring right now. Read More in a modern router, mainly because it increases the security of your home network and makes it more convenient for everyone involved.

Routers with guest access can set up a separate sub-network with its own SSID and password. The guest feature means you don’t need to share your main Wi-Fi password. It also prevents guests from accessing other areas of the router, such as file sharing on the home network.

Our Device Recommendations

Maybe you don’t have the time or energy to do a lot of research. Or maybe you don’t care enough to learn the nuances. Either way, if you just want someone to tell you what to buy, you’ve come to the right place. All of the following devices assume you have a cable high-speed internet connection from your ISP.

Modems

    hi,
    there is a good amount of interresting informations provided, but i would like to add some:
    - 'if only 1 ethernet, it is a modem' most often true but not allways
    - '5 ethernet it is a router' yes for ethernet (wan) to ethernet (4*lan)
    but a modem-router would most often have only 4 ethernet and one specific port (cable or phone)
    - for x-dsl (adsl, vdsl, ...) you must choose a modem that is compatible (ask your isp)
    settings could be difficult if the isp does not give the correct info and the isp is not known by the modem
    - some isp provide voip services. then most often you must use the isp modem
    - you may also receive tv signal and there too a specific router/modem will be required

    this article speaks solely about the very low-cost end-user equipment (below 1K$) the professional equipments are way more expensive (REAL cisco, ...). even so the equipments presented here should be adequate even for sme's

    the provided info's seems very usa-centric. sorry, but 'US or ROW' (Rest Of the World) is so 'old time' now

      Hey Shaoul, thanks a lot for adding those details. You're right, especially the part about DSL connections requiring a different kind of modem than cable (because they use telephone lines, not coaxial cables). And yes, this was strictly with consumer equipment in mind, nothing about professional grade stuff.
