How often should you restart or replace your router?

How often should you restart your router?

Reboot a home router roughly once a month as routine maintenance, and immediately whenever you notice sluggish speeds, dropped connections, or a security advisory telling you to.

A monthly cadence is the number that shows up again and again in guidance from ISPs and router manufacturers, and it holds up under scrutiny. Routers are small computers running embedded Linux or similar firmware, and like any computer, they accumulate cached processes and half-closed connections in RAM over weeks of uptime. A reboot flushes that memory and gives the CPU a clean slate, which is why a router that felt sluggish before a restart often feels snappier ten minutes later.

There's a security angle too, and it's not hypothetical. Many home routers rotate to a new public IP address on reboot, which quietly resets the address that outside scanners and bots had been probing. The FBI's Internet Crime Complaint Center made this concrete in a May 2025 advisory about criminal proxy networks built from compromised home routers, instructing consumers to reboot their devices as one of several defensive steps, alongside applying firmware updates and disabling remote administration. That's a federal law enforcement agency treating a reboot as an actual mitigation step, not a stalling tactic support reps use to end a call.

If you're rebooting more than once a week just to keep the internet usable, that's not a maintenance rhythm anymore, it's a symptom. At that point the problem is more likely overheating, a failing power supply, interference from neighboring networks, or a router that's simply worn out, and no amount of unplugging fixes those root causes.

What actually happens when you reboot a router

A reboot clears the router's working memory, closes stale network sessions, lets it request a fresh IP address, and gives it a chance to rescan for a cleaner Wi-Fi channel.

Picture the router's memory the way you'd picture a browser with forty tabs open. Nothing has crashed, but every open connection, cached DNS lookup, and half-finished data transfer is quietly eating RAM the device could use for actual traffic. A power cycle closes all of it at once. On low-memory consumer routers, especially older ones, this is often the single biggest reason performance degrades over weeks of uptime and then mysteriously fixes itself after a restart.

Rebooting also forces the router to rejoin its network cold, which means it renegotiates its connection with your modem or ONT and typically requests a new public IP address from your ISP. That matters for two reasons: it can resolve odd modem-router handshake issues, and it interrupts anyone who had mapped your old address for scanning or attack purposes.

One underappreciated benefit is channel selection. Wi-Fi routers pick a radio channel on boot based on what's congested at that moment, and neighborhood congestion shifts throughout the day as other households' devices come and go. A router that booted at 2am chose its channel based on 2am conditions and never revisits that choice unless you restart it or its firmware includes automatic channel-hopping, which many budget models don't.

Reboot vs. reset: don't confuse the two

A reboot is a simple restart that preserves your Wi-Fi name, password, and settings; a factory reset wipes everything back to out-of-box defaults.

This distinction trips people up constantly, and it's worth being precise about it before you touch anything. Rebooting means power-cycling the device, typically by unplugging it for thirty seconds to a minute and plugging it back in, or by using the restart option in the router's app or web interface. Everything you configured stays intact: your network name, your password, port forwarding rules, guest network, all of it.

A factory reset is different and far more drastic. It's usually triggered by holding a small recessed button for ten to thirty seconds, and it erases every custom setting, reverting the router to whatever configuration it shipped with. You'd only want to do this if you're troubleshooting a serious fault, selling the router, or migrating to a completely new setup, because afterward you'll need to redo the entire configuration from scratch, including reconnecting every device in the house.

If a guide or a support agent tells you to "reset" your router when they mean a quick power cycle, that's loose language, and it's worth asking which one they actually want before you find yourself re-pairing a dozen smart home devices for no reason.

How often should you replace your wifi router?

Plan on replacing a home router every three to five years; tighten that to two or three years in a heavy-use household with many connected devices.

This is where manufacturer guidance actually converges on a fairly narrow range. Netgear has told consumers three years is a reasonable point to consider an upgrade, while representatives from Google and Linksys have both pointed to a three-to-five-year window as appropriate for most households, according to reporting from Consumer Reports. Eero, Amazon's mesh brand, lands in a similar three-to-four-year range. None of these are hard expiration dates, they're reflections of how fast Wi-Fi standards, security protocols, and typical household bandwidth needs move.

Household composition changes the math more than age alone does. A house running a handful of laptops and phones can comfortably stretch a router toward the five-year mark. A house with a few 4K streaming devices, cloud gaming, video doorbells, smart thermostats, and a dozen other always-connected gadgets is putting far more concurrent load on the same processor and radio chips, and that's the profile where a two-to-three-year cycle makes more sense.

Consumer Reports also found that a meaningful share of consumers, about one in five, hold onto a router for more than four years past whatever the recommended window was, which suggests the gap between guidance and actual behavior is wide. If your router falls into that camp, it's worth checking its status rather than assuming that because it still connects, it's still fine.

For a side-by-side look at current router options across price tiers, our wifi router hub breaks down what's worth considering when you do decide to upgrade.

Signs your router needs replacing, not just rebooting

Overheating, an end-of-life status from the manufacturer, persistent slow speeds that survive a reboot, and random restarts all point to hardware replacement rather than a quick power cycle.

The clearest signal is also the most official one: check whether your router still appears on its manufacturer's active support list. The FBI's May 2025 advisory on router-based cybercrime specifically flagged devices that no longer receive firmware updates as prime targets for compromise, noting that routers manufactured around 2010 or earlier typically stopped getting manufacturer patches years ago. If your model has aged off that list, no amount of rebooting closes the security gap that unpatched firmware leaves open.

Physical symptoms matter too. A router that's hot to the touch even in a well-ventilated spot is a sign internal components are stressed, and that kind of heat tends to get worse, not better, over time. Indicator lights that flicker unpredictably, buttons that stop responding, or a device that reboots on its own without you touching it are all consistent with aging hardware rather than a software hiccup a restart can fix.

Performance is the other half of the picture. Run a wired speed test with a laptop plugged directly into the router via ethernet and compare it against what your ISP advertises. If the wired number matches your plan but Wi-Fi speeds lag badly throughout the house, and a fresh reboot doesn't change that, you're likely looking at aging radio hardware or a router that was undersized for your home's layout from the start, not a memory problem a restart would solve. Our best wifi router guide and our wireless router picks both group current options by how many devices and how much square footage they're built to handle, which is the more useful lens than birthdate alone when you're deciding whether to upgrade.

Does upgrading to a newer Wi-Fi standard justify replacing early?

It can, if your other devices already support the newer standard and you're on a plan fast enough to benefit, but a Wi-Fi standard alone isn't a reason to replace a router that's otherwise healthy.

The Wi-Fi Alliance introduced Wi-Fi CERTIFIED 7 in 2024, built on the IEEE 802.11be standard that was formally published in July 2025. Per Wi-Fi Alliance documentation, Wi-Fi 7's 320 MHz channels in the 6 GHz band are engineered to roughly double the throughput ceiling of Wi-Fi 6, and its multi-link operation lets a device use more than one band at once for steadier connections in a busy household. Wi-Fi 6 itself, ratified as IEEE 802.11ax, began shipping in consumer routers starting around 2019 to 2020 and is now solidly mainstream.

The catch is that these gains only show up when the client device on the other end, your phone, laptop, or streaming box, also supports the newer standard. A five-year-old laptop with a Wi-Fi 5 chipset won't get faster just because you bought a Wi-Fi 7 router; the connection negotiates down to whatever the older device supports. So the standard is a legitimate reason to upgrade only when you already own several newer devices that can use it, or when you're also upgrading your internet plan to speeds a Wi-Fi 6 router would bottleneck.

If you're shopping specifically because your devices have moved past what your current router supports, it's worth comparing options built around wireless standards side by side rather than replacing on a hunch that newer is automatically better for your specific setup.
