Quick answer: A WiFi router typically lasts 3 to 5 years. Most do not fail outright; they fall behind. Firmware updates stop, newer devices outrun the old WiFi standard, and the hardware runs hot enough for long enough that speeds and range fade. If your router is 5 or more years old, predates WiFi 6, or needs a restart every few days, it is due for replacement.

Key Takeaways:
- Routers last 3 to 5 years on average. Heat wear, ended firmware support, and outdated WiFi standards are what end a router's useful life, not a single dramatic failure.
- The clearest signs your router is going bad: needing a restart every few days, speeds far below your plan on every device, shrinking range, and no firmware update in over a year.
- A restart, a factory reset, and a firmware check take 20 minutes and rule out the easy problems. If those do not help and the router predates 2019, a WiFi 6 router is the fix.
Not sure which box is the problem?
If your internet drops for every device at once, including anything plugged in by Ethernet, the modem may be the culprit instead. Our guide to how long modems last and the signs one is going bad covers that side. This article is about the router: the box that makes your WiFi.
How Long Do Routers Last?
A wireless router lasts 3 to 5 years of useful life. Well-built models can keep running for 7 or 8 years, but "still powers on" and "still doing its job" are two different things. By year five, most routers have stopped receiving firmware updates, cannot keep up with the number of devices in a modern home, and are one or two WiFi generations behind the phones and laptops connecting to them.
That is why a router that seems to work can still be the reason your WiFi feels slow.
Why Routers Wear Out
Three things end a router's useful life:
- Heat. A router runs 24 hours a day, every day. Its processor and radios generate constant heat, and the components around them (capacitors especially) degrade faster the hotter they run. A router in a closet, a cabinet, or on top of a warm cable box ages faster than one on an open shelf.
- Ended firmware support. Manufacturers typically issue firmware updates for 3 to 5 years after a model launches, then stop. Once updates end, security holes stay open and compatibility bugs with newer devices never get fixed. An unsupported router is a security problem, not only a performance one.
- Outdated WiFi standards. Each WiFi generation adds speed, range, and the ability to serve more devices at once. A WiFi 5 router from 2016 was built for a home with 8 to 12 devices. The average home now has 20 or more, and the router simply was not designed for that load.
Router Lifespan by WiFi Generation
The WiFi standard printed on the box is the fastest way to gauge a router's age and how much life it has left.
| WiFi Standard | Also Called | Introduced | Status in 2026 |
|---|---|---|---|
| WiFi Standard: WiFi 4 | Also called: 802.11n, "Wireless N" | Introduced: 2009 | Status: Replace now. No firmware support, no gigabit capability. |
| WiFi Standard: WiFi 5 | Also called: 802.11ac, "AC1200," "AC1900" | Introduced: 2013 | Status: Aging out. Fine for light use in small homes; most models no longer get updates. |
| WiFi Standard: WiFi 6 | Also called: 802.11ax, "AX1800," "AX3000" | Introduced: 2019 | Status: Current sweet spot. Handles gigabit plans and 30+ devices. |
| WiFi Standard: WiFi 6E | Also called: 802.11ax on 6 GHz, "AXE" | Introduced: 2021 | Status: Current. Adds an uncrowded band for dense apartments. |
| WiFi Standard: WiFi 7 | Also called: 802.11be, "BE3600," "BE9700" | Introduced: 2024 | Status: Newest. Built for multi-gig plans and the longest runway. |
If your router's model name starts with "AC" or "N," it is WiFi 5 or older. If it starts with "AX" or "BE," it is WiFi 6 or newer and probably has years left.
30-second router age check
How old is your router?
Pick the year you bought it (or the year your provider gave it to you) and we'll tell you where it stands.
Past its useful life. It predates WiFi 6, has almost certainly stopped getting firmware updates, and was built for far fewer devices than you own now. Replacing it is the single biggest WiFi upgrade available to you.
Shop WiFi 6 RoutersTested refurbished, 90-day warranty and 30-day returns. Most pay for themselves in under a year of skipped rental fees.In the gray zone. A WiFi 6 router from this window is probably fine. A WiFi 5 model bought on a budget in 2019 or 2020 is nearing the end of its firmware support and struggles with today's device counts. Check the model name: "AX" means keep it, "AC" means start planning.
Shop Mesh WiFi SystemsIf your router is fine but your coverage is not, mesh fixes dead zones without replacing everything else.Your router is not the problem. Anything sold in 2022 or later is WiFi 6 at minimum and still supported. If WiFi is slow or spotty, the cause is placement, interference, an old modem, or a plan slower than you think. Work through the checks further down this page before spending anything.
One room with weak signal?A WiFi range extender reaches the room your router can't, and keeps the router you already have.Signs Your Router Is Going Bad
Routers rarely die with a bang. They decline in ways that are easy to blame on the internet provider, the phone, or the weather. Here is what a failing or outdated router looks like from the couch.
You Restart It Every Few Days
This is the most common sign and the one people tolerate longest. A healthy router should run for months without a reboot. If a restart fixes your WiFi for a day or two and then the slowdowns return, the router's memory or processor is struggling to keep up. Aging components and firmware that was never updated for modern traffic both cause this pattern.
Speeds Are Far Below Your Plan on Every Device
Run a speed test on a laptop plugged into the router by Ethernet, then run one over WiFi standing next to the router. If the wired test matches your plan and the WiFi test is a fraction of it, the router is the bottleneck. A WiFi 5 router can deliver roughly 300 to 500 Mbps in ideal conditions and far less through walls, so anyone on a gigabit plan with an older router is paying for speed they never see.
The Signal Doesn't Reach Rooms It Used To
Range that shrinks over time is a hardware symptom. The radio amplifiers in a router weaken with years of heat, and the result is a signal that used to reach the back bedroom and now stops at the hallway. If nothing changed in your home and coverage got worse anyway, the router is wearing out.
Devices Drop Off and Reconnect
Phones that show full WiFi bars but no internet, a laptop that disconnects during video calls, a smart TV that buffers on a plan fast enough to stream four things at once: these are signs the router is overwhelmed. Older routers were designed to juggle a handful of connections at a time. Once you pass 15 to 20 devices, they start dropping the ones they cannot keep up with.
The Router Runs Hot to the Touch
Warm is normal. Hot enough that you pull your hand back is not. Excessive heat is both a cause and a symptom of a failing router: the components are working harder than they were designed to, and the heat accelerates their decline. Discolored or warped plastic is a late-stage version of the same problem.
No Firmware Update in Over a Year
Log in to your router's admin page (our router login guide walks through it) and check the firmware date. If the last update is more than a year old, the manufacturer has most likely ended support. That means known security vulnerabilities stay open, and every device on your network is exposed through the one box that is supposed to protect them.
Newer Devices Connect Slowly or Not at All
A new phone that connects fine everywhere except home, or a smart device that refuses to finish setup, often points to an old router that does not speak the newer WiFi standards properly. Everything is backward compatible in theory; in practice, old firmware and new devices make a bad combination.
The Lights Do Something New
A WiFi light that blinks amber, a power light that flashes on its own, or a router that reboots itself without being asked are all hardware warnings. If the pattern started recently and a factory reset does not clear it, the router is failing.

What's your WiFi problem?
Try This Before You Replace It
Four checks, about 20 minutes, and they resolve a surprising share of "my router is dying" complaints.
- Power cycle it properly. Unplug the router and the modem, wait a full 30 seconds, plug the modem in first, wait for its lights to settle, then plug in the router. Our restart and power cycle guide covers the order and timing that make this work.
- Update the firmware. Log in to the admin page and check for an update. Many routers ship with auto-update off. If an update is available, install it and give the router a week before judging.
- Factory reset. Years of accumulated settings, half-applied updates, and forgotten port forwards can bog a router down. A reset wipes the slate. You will need to set up your WiFi name and password again, so note them first. The restart vs. factory reset guide explains the difference and how to do each.
- Move it. A router behind the TV, in a cabinet, or in a basement corner performs like a router two generations older. Central, elevated, and in the open is the goal.
If the router still restarts itself, still runs hot, or still delivers a fraction of your plan after all four, the checks have done their job: they confirmed the hardware is the problem.
Rebooting and it still won't behave?
A router stuck in a reboot loop or dropping the connection every few minutes has its own set of causes. Start with the restart and power cycle guide, and if the pattern survives a factory reset, the hardware verdict is in.
Is It the Router or the Modem?
The two boxes fail differently, and the test takes two minutes.
- Everything drops at once, wired devices included: the modem or the line from your provider. Check the modem's lights and see our modem lifespan guide.
- Wired devices are fine, WiFi devices are not: the router.
- One room is bad, the rest is fine: coverage, not failure. A range extender or a mesh system fixes it without replacing the router.
If you have a combo unit from your provider (one box that is both modem and router), the router half almost always ages out first. Pairing your own router with that box in bridge mode, or replacing the whole thing with a purchased modem router combo, gets you out of the monthly rental fee at the same time.
Best Replacement Routers in 2026
Every router works with every internet provider, because a router connects to your modem or fiber gateway rather than to the provider directly. That means you can shop on home size and plan speed alone. These picks are sold directly by ModemGuides as tested refurbished units unless noted, with a 90-day warranty and 30-day returns.

How to Make Your Next Router Last Longer
- Give it air. Open shelf, nothing stacked on top, not inside a cabinet. Heat is the number one thing that shortens a router's life.
- Turn on automatic firmware updates. Most current routers offer it in the app. It keeps the security patches coming without you remembering to check.
- Use a surge protector. Small surges from storms and grid fluctuations cause cumulative damage over years. A basic surge strip is cheap insurance.
- Buy one generation ahead of your plan. A WiFi 6 router on a 300 Mbps plan has headroom for the day your plan gets faster. A WiFi 7 router bought today should still be current in 2030.
- Restart it monthly. Not because it needs it, but because it clears memory and applies any pending updates. A reboot schedule in the router's settings does it for you.
Frequently Asked Questions
How often should you replace your router?
Every 4 to 5 years for most homes. Replace sooner if it predates WiFi 6 (2019), has stopped receiving firmware updates, or needs restarting more than once a week. Replace later if it is a WiFi 6 or newer model that is still supported and still meets your plan speed.
Can a router just go bad?
Yes. Routers wear out from heat, power surges, and years of continuous operation. The usual failure is gradual: shrinking range, more frequent freezes, and dropped devices, rather than a router that suddenly stops working. Sudden total failure usually means a dead power supply, which is sometimes replaceable on its own.
Do routers slow down over time?
The hardware does not get slower, but the world around it does get faster. More devices, faster internet plans, and newer phones and laptops all demand more than an older router was designed for. Firmware that stops being updated also leaves compatibility bugs in place. The router performs the same; it falls behind.
How do I know if my router is outdated?
Check the model name. "N" or "AC" in the name means WiFi 4 or WiFi 5, which is outdated in 2026. "AX" means WiFi 6 and "BE" means WiFi 7, both current. You can also log in to the admin page and check the firmware date: no update in over a year usually means support has ended.
Should I replace my router or my modem?
If wired devices work fine and only WiFi devices have problems, replace the router. If everything drops at once, wired included, look at the modem first. If you rent a combo gateway from your provider, replacing it with your own modem and router (or a purchased combo) fixes the problem and ends the monthly fee.
Is a refurbished router a good replacement?
Yes, and often a better one than a new budget router at the same price. Routers lose price much faster than performance, so a refurbished WiFi 6 or WiFi 7 model gives you stronger hardware and longer remaining firmware support than a new entry-level unit. ModemGuides tests every router by hand and backs it with a 90-day warranty and 30-day returns.
Does a new router make internet faster?
It makes WiFi faster, up to the limit of your internet plan. If your plan is 500 Mbps and your WiFi 5 router delivers 150 Mbps in the living room, a WiFi 6 router will get you much closer to 500. It will not make a 500 Mbps plan deliver 1,000. Run a wired speed test first so you know the ceiling.
