You need to be connected to your modem in order to send and receive data from the web; your router lets you do that without the need for a wire. It's basically a big, fancy antenna for your modem that lets you connect with it wirelessly, over Wi-Fi. You can also use that local Wi-Fi network to connect with other devices at home, like printers or remote storage servers.
It depends on what you need and how many people and devices need to connect, but a small- to medium-sized home or apartment can probably get by with a well-tested dual-band router in the $100 range. If your home is larger, it's probably worth spending more on a mesh system that can spread more consistent speeds from room to room. If you're working from home, gaming online or sharing bandwidth with multiple housemates or family members, upgrading to something like a high-speed tri-band router is probably a good investment too.
The old-fashioned way is to plug the thing in and connect it to your modem via Ethernet cable, then type its IP address into a browser's URL bar to begin the setup. The easier, more modern way is to use the router's app, which will typically walk you through setup in about 5 to 10 minutes. After setup, you can also use either approach to access the router's settings or change your Wi-Fi password.
You can think of your router like a radio -- it sends and receives signals through airwaves. Whereas a radio picks up audio broadcasts in AM or FM airwaves, a Wi-Fi router sends and receives data through 2.4 and 5GHz airwaves (as well as 6GHz airwaves if it's a fancy Wi-Fi 6E router).
Nearly all routers include separate radios for those bands, which lets you connect to whichever band is best. Some routers will automatically steer your connection between the multiple bands available, but you can usually turn that off as well, making each band its own, separate Wi-Fi network. The 2.4GHz band offers a better range than higher bands, but speeds are limited. With 5GHz (or 6GHz), you'll be able to hit much faster speeds, but those speeds will drop off at range faster than you'll see with 2.4GHz.
In general, the 5GHz band is going to be your best bet for a reliable, high-speed connection at close and medium range, while the 2.4GHz band is great for devices at the far reaches of your Wi-Fi network, where the improved range is worth the speed trade-off.
In most cases, you won't need to worry about updating your router more than once every five years or so, if not longer. That said, there are a few things to watch for that might give you good reason to consider something new.
First, you should know that the Wi-Fi standard gets a generational update once every several years. The latest of which, Wi-Fi 6, ushered in faster top speeds and better efficiency for crowded networks with lots of devices. The next big update, Wi-Fi 7, is expected to arrive in 2024, and it stands to offer even faster top speeds and better use of the 6GHz band once it becomes a fully ratified standard. You shouldn't feel compelled to upgrade to a new generation as soon as it arrives, but it's definitely something to keep an eye on if you're looking for top-tier Wi-Fi performance.
More important is to make sure that your router is still receiving regular firmware updates against the latest security threats. If it isn't, then it might make sense to go ahead and upgrade. I'd also look for something new if my router didn't support WPA3, the most recent Wi-Fi security protocol.
If you're thinking of upgrading because your home's internet speeds aren't satisfying, try testing those speeds out across different distances (and remember that you can connect only as fast as your ISP plan allows). If speeds seem fine when you're close to the router, but they plummet when you're a few rooms away, then upgrading to a router with stronger radios or a mesh router with multiple devices, could be a worthwhile investment.
The fastest Wi-Fi router in CNET's testing was the Linksys Hydra Pro 6, which retails for $200. On a 940Mbps fiber internet connection, it delivered average download speeds of 536Mbps and upload speeds of 467Mbps across our testing facility.
Mesh routers use multiple devices to relay a better Wi-Fi signal throughout your home, with fewer dead zones. It's definitely the right approach if you live in a large, multi-story home or if there are multiple spots in your home where you can't connect as reliably as you'd like.
There are lots of great mesh systems up for sale at this point, and prices have come down significantly in the last few years. For more information and our top recommendations, be sure to check out our full rundown of the best mesh Wi-Fi systems of the year.
The best fit for your network depends on a few factors, from the size and layout of your home to the content you stream. We've tested dozens of the latest models to help find options for every situation. Expect regular updates to this post as we continue testing networking devices periodically. When we find a new router that merits strong consideration, we'll add it to this list with links to our most recent test data so that you can always find the best router.
Best of all, when tested against other, similar routers from names like Asus and Netgear, the AX21 held its own with faster download speeds, better range and low latency too. Add in a functional band steering mode that automatically steers you between the 2.4 and 5GHz bands within a single network, plus guest network controls and even a quality of service engine for prioritizing traffic to the most important devices on your network, and you're looking at a decent home networking upgrade that's as simple and affordable as it gets. It isn't powerful enough to max out speeds on a gigabit network, but it can still hit consistent close-range speeds near 700Mbps or so, which is more than enough for most households.
If you've already got a budget router running your network and you're ready to upgrade to something more powerful, the Linksys Hydra Pro 6 belongs high on your list. With a dual-band, AX5400 build, full support for Wi-Fi 6, and 160MHz channel support for moving data more efficiently, it was an excellent performer in my speed tests, even managing to outperform flashier picks like the also-great Asus RT-AX86U.
The Hydra Pro 6 is a touch pricey as dual-band routers go, but the steady, consistent performance makes it a standout. Try to catch it on sale if you can, but if you just want a reliable, no-frills router that can keep up with gigabit speeds, look no further.
For the best performance from your mesh router, you'll want to prioritize getting one with support for Wi-Fi 6, plus a tri-band design that includes three separate bands of traffic: the usual 2.4 and 5GHz bands, plus an additional 5GHz band that the system can use as a dedicated wireless backhaul for transmissions between the router and its satellites. Most mesh routers like that cost at least $300 or even $400, but the TP-Link Deco W7200 gets you there for $200.
That's the best deal I've seen for a tri-band mesh router with support for Wi-Fi 6, and sure enough, it's an excellent performer. In fact, the only system that managed to outperform it outright in my at-home speed tests is the AX6000 version of Netgear Orbi, which costs more than three times as much (keep reading for more on that one). On top of that, TP-Link's setup process is about as easy as it gets, with satellite extenders that automatically join the mesh as soon as you plug them in.
Most noteworthy is the router's latency management. In fact, it leads all of the routers I've ever tested, gaming or otherwise, with the lowest average latency across all of my tests, which online gamers will definitely appreciate. Something else you'll appreciate: It offers an excellent mix of app-based controls and features, including a mobile boost mode, allowing you to prioritize gaming traffic to your phone at the touch of a button.
Gaming features aside, the RT-AX86U offers full support for Wi-Fi 6, with strong, stable speeds and good range. If you need additional range, you can add other Asus "AIMesh" devices to your home network to make it the centerpiece of a mesh.
That checks off all of the boxes that most people want from a good gaming router, and it gets you there at a price that isn't too painful for us to recommend. Even if you aren't a gamer, this is still one of the best Wi-Fi 6 routers you can buy right now.
It isn't as fully featured as systems that cost more, and it doesn't support Wi-Fi 6, but aside from that, the budget-friendly, AC1200 version of the Netgear Orbi mesh router stands out as a clear value pick in the mesh category. Currently priced around $50 for a three-device setup with the Wi-Fi router and two satellite extenders, it's an incredibly affordable system that managed to keep up with both Nest Wifi and the Wi-Fi 5 version of Amazon's Eero mesh router in our speed tests, and it'd be a great fit in homes with internet speeds of 300Mbps or less.
In fact, of those three systems, Netgear Orbi clocked in with the fastest average top speed at close range, and it displayed surprisingly strong signal strength when we mapped those signals out at the CNET Smart Home. I even like the design, with clever contours on top that vent out heat in style. If you're curious about mesh routers but put off by the high asking price, give this bargain system a shot.
Starting around $400 for the two-piece setup seen here, the AX6000 version of the Netgear Orbi is far more expensive than the dual-band version listed above, but it's also a lot more powerful. With a second 5GHz band serving as a dedicated backhaul for system transmissions between the router and its satellites and full support for Wi-Fi 6, the system is still our top-tested mesh router, with the best scores in both our lab-based top-speed tests and our at-home mesh coverage tests.
