![]() Any Wi-Fi device in range of that network can use whatever password you've set to connect wirelessly to the router, and through it, to the modem and the web. From there, that router broadcasts a Wi-Fi network. ![]() Instead of wiring each of your devices to your modem, you just wire a router to it. Chris Monroe/CNET Your router connects your devices to your modem without wires This Asus router offers wireless access to your modem's connection with the web (hence the antennas). Gee, if only there was a device for that, some way to "route" all of those wireless signals to the right place. For that, you'll need a way for those devices to connect to your modem without wires at all. Wired connections to the modem like that are great for a connection that's as fast and reliable as your ISP allows, but they aren't practical if you want to be able to connect from anywhere in your house, or if you want to use things like wireless smart home gadgets. You'd plug your modem into your home phone line for a dial-up connection with your internet service provider, and then you'd wire the modem to your computer to connect that computer to the web. In the early days of the internet, a modem was all most people used to get online. All of that happens within a fraction of a second, and you see it play out on your screen because your modem is connecting you with Amazon through the web. Then, Amazon responds by sending the confirmation that your bulk order of red gummy bears is, indeed, in your cart. Here's a practical example: When you're at home shopping on Amazon and you click "Add to cart," your modem sends that request to Amazon's servers. What's more, plenty of home internet providers will let you skip an equipment rental fee if you use your own modem or router, so buying your own hardware could save you money over the long run, too. ![]() From there, you'll have a much easier time fixing problems as they arise, and you'll have a better sense of when and how to best upgrade your network, too. A good start is to build a sense of familiarity with what those different devices are doing, and how they work together to get you online. There's no shame in that, but it's still well worth understanding how the Wi-Fi works. All of that depends on the hardware running our home networks - typically a modem and a router, or a gateway device that combines the two - but for a lot of us, that hardware is hard to understand and best left to technicians and tech-savvy friends and family to set up on our behalf. The download speed is always the larger number, and is usually listed first-in some cases, it is the only number listed.Our home internet connections have never been as important as they are now, with millions of us continuing to work, learn and socialize from home. ISPs may list the download and upload speeds as two numbers, such as 300/20 Megabits per second (Mbps). Upload (or upstream) speed represents how fast you can send data to Internet services, like when you upload photos to Facebook. This is a nuisance for any WiFi user, but it’s especially frustrating for streamers or gamers, who rely on a steady WiFi connection.ĭownload (or downstream) speed denotes how fast data comes into your home when you’re doing things like streaming movies from Netflix. If your modem can’t support the speed of your service, it will create a bottleneck, resulting in a slow or spotty connection. When purchasing a cable or DSL modem, be sure to choose the appropriate type of modem for your service, and be sure that it’s compatible with the download and upload speeds you subscribe to from your ISP. Cable modems are most prevalent in retail, but you won’t find Fiber-based products in stores-services like Verizon FiOS and AT&T U-verse require consumers to use unique devices for their respective services. There are three kinds of modems-Cable, DSL, and Fiber-that operate via different cable mediums depending on your Internet Service Provider (ISP).
