Yes, Routers Need to Be Replaced. Signs You Need a New One

There can be a lot of fingers to point when it comes to slow internet. Your internet provider could be throttling your speeds, your plan might be too slow for all devices using it or your router may be in the wrong spot.

But sometimes, you’ll need to upgrade your older equipment altogether. In general, experts recommend swapping your router every five years at a minimum. Make that every two to three years if you use lots of smart home gadgets, or if you make a regular habit of buying the latest laptops, phones and other primary Wi-Fi devices. That means there are probably lots and lots of us that would stand to benefit from upgrading to a new router in 2024. Here’s how to wrap your head around all of that, and make the right upgrade at the right time.

Are your speed issues the router’s fault?

A good router should be able to take full advantage of whatever internet speeds you’re paying for — but if your network seems more sluggish than you’d expect, then you’ll want to take some steps to be sure that your router is, indeed, the culprit.

Sometimes, a simple reboot is all your network needs, so start with the obvious and unplug both your router and your modem, then plug them both back in. Dave Coleman, a Wi-Fi expert, author and director of wireless networking in the office of the CTO at Extreme Networks, the company that ran the Wi-Fi at Super Bowl 55, also recommends rebooting the Wi-Fi drivers on your phone, laptop and other important client devices.

“It’s amazing how that’ll solve like 90% of the problems, because the drivers are the interface between the radio and the operating system, and they can get discombobulated,” Coleman says. “I know it sounds simple, but it’s the first troubleshooting thing people should do.”

It’s also a good idea to try bypassing the router altogether, which you can do by wiring your computer directly to the modem with an Ethernet cable. Is that hardwired level of online performance noticeably better than what you’re getting when you’re connected wirelessly at a short distance, in the same room as the router? That’s a clear sign that the router is falling short of your network’s potential.

If problems like those persist, try running some speed tests in various spots around your home using a few different devices — both your phone and your laptop, for instance. I like the Ookla speed test, which is fast, free, reliable and easy to use — you can run it in your browser by clicking here, or you can download Ookla’s speed-testing app to your Android or iOS device, or even to an Apple TV. (Ookla is owned by the same parent company as CNET.) Whatever devices you use, those results should give you a clearer sense of whether the problem is tied to a specific client device or location in your home, or whether it’s a bigger issue affecting everything.

With the numbers giving you a better understanding of the status quo, making some quick tweaks can give you a nice speed boost. Try repositioning the router to a spot that’s more open and central within your home, preferably in a location that’s as high as possible. While you’re at it, adjusting the angle of the antennas might help boost the signal to specific spots around the house. It’s also a good idea to blast the ports in the back and the airflow vents with a can of compressed air to break through dust build-up — gunk like that can cause your router to overheat and its performance to dip.

None of that worked and your internet still stinks? Yeah, you probably need a new router.

Is it time to upgrade to the next generation of Wi-Fi?

Router technology and security are always improving, and we’ve seen some significant jumps in the past few years with the arrival of Wi-Fi 6, Wi-Fi 6E and, in the past several months, Wi-Fi 7. Generational advances like those leave yesterday’s routers in the dust, so it’s worth upgrading to a router that supports them as soon as it makes sense for you to do so — even if the one you’re using now is still getting the job done.

Outside of that, the mere fact that so many of us are spending so much more time at home these days makes the idea of upgrading your router even more compelling. 

“People are running into problems where Mom’s trying to do a Zoom call, but it goes south, because the kids are upstairs streaming Netflix videos,” Coleman says. “That’s one sign that you might need to upgrade your Wi-Fi network.”

Upgrading to Wi-Fi 6, a newer generation of Wi-Fi that’s better suited for dense, crowded environments where you have lots of devices competing for bandwidth, is definitely one way to give your network a boost. And with the arrival of Wi-Fi 7 in 2024, you can now find Wi-Fi 6 and 6E devices for significantly reduced prices.

Do you need a mesh router?

Is your connection strong in some places throughout your home, but weak or nonexistent in others? If so, upgrading to a mesh system, which uses multiple devices to extend the range of your network and spread a steadier signal throughout your entire home, might be one of the most meaningful tech upgrades you can buy into.

Mesh routers have been around for several years now, but it’s only in the last year or two that we’ve seen decent options available for less than $300. Now, in 2024, you’ve got plenty of systems to choose from, with prices ranging from entry-level models that cost as little as $150 or less to top-of-the-line systems that cost as much as $1,000.

For my money, the best strategy for that spectrum of mesh options is to aim for the middle ground. Tri-band design, which adds in a second 5GHz band to serve as a dedicated backhaul channel for transmissions between the main router and its satellites, has been the biggest difference-maker in my tests, and it’s worth paying a little extra for it. 

Your router can’t work miracles

One last point: It’s important to understand that your router doesn’t generate speed or bandwidth — it takes whatever bandwidth you’re paying for from your internet service provider and sends it out into your home so that wireless devices can connect. If that incoming bandwidth is limited to begin with, there’s really not much your router can do about it.

Eventually, improvements to things like satellite internet and continued 5G and fiber deployments should help bridge the bandwidth gap in parts of the country that lack access to high speeds. But until that happens, paying extra for an upgraded router is probably overkill.

“I wish there was an answer to say, ‘Yeah, you could upgrade your router, and that’ll solve your bandwidth problem on the ISP,'” Coleman says. “But the answer is not really.”

In a “small pipe” situation like that, Coleman’s recommendation is to focus on conserving your bandwidth — especially in the situation he described earlier, where Mom’s work calls are dropping due to the kids’ Netflix habits. His suggestion: Look for a router with good parental control settings.

“If you’re a parent, you can do time settings and firewall settings to restrict access of certain kinds of applications, as well as certain times when certain individuals could use it,” Coleman says. “My kids are grown now, but I used to do it back in the day!”
