A router can look perfectly healthy while still developing temporary software or connectivity problems that make home Wi-Fi less reliable. A normal reboot can often clear those issues without changing saved network settings or replacing equipment.
For security, NSA guidance recommends rebooting home routing devices at least weekly. Manufacturer maintenance recommendations vary, so owners should also follow guidance for their specific router model.
A router is an always-on network computer that manages connections, addresses, security functions and wireless traffic. Restarting it clears volatile system state and can resolve some temporary problems, although repeated issues may point to firmware, hardware or network problems that need further troubleshooting.
Weekly reboots match federal guidance
Federal cybersecurity guidance recommends regularly rebooting home routing devices. NSA guidance says users should schedule a reboot at least once a week to help remove non-persistent malicious code and improve security.
Router manufacturers also provide reboot functions that can help resolve temporary performance or connectivity problems. Some models support automatic weekly or monthly schedules, while others treat rebooting primarily as a troubleshooting step.
Firmware updates should remain a separate priority. Many routers restart automatically when an update is installed, so users should keep firmware current rather than relying on routine reboots as a substitute for software updates.
Why does a router need restarting?
A home router is essentially an always-on computer, and many routers use Linux-based or other embedded firmware. It can manage services such as network address translation, address assignment, firewall rules, quality-of-service controls and Wi-Fi radios.
Routers continually create and remove temporary network state as devices communicate. Connection-tracking entries normally expire automatically, but software bugs, resource exhaustion or unusually heavy workloads can still cause instability on some devices.
Restarting clears volatile memory and active connection state, allowing network services to start fresh without erasing saved settings. That can resolve some slowdowns, dropped connections and devices that refuse to reconnect.
Smart homes can benefit from weekly restarts
A modern smart home may have dozens of connected devices, from cameras and thermostats to televisions and voice assistants. Those devices can create many simultaneous network sessions and place greater demands on a router.
A weekly reboot is consistent with NSA security guidance for home routers and can also provide a convenient opportunity to clear temporary software state. If a network requires daily or very frequent restarts to remain usable, that points to a problem worth troubleshooting rather than a normal maintenance requirement.
Little-known fact: The average U.S. smart home now has 22 connected devices and faces roughly 29 cyberattack attempts every day.
What happens during a router reboot?
A proper reboot stops the router’s operating processes and starts them again. Volatile memory is refreshed, while active connections are terminated and rebuilt as devices reconnect.
Temporary network state, including active connection tracking, is recreated after startup. Devices briefly lose network access during the process, but stored settings such as Wi-Fi names and passwords remain intact.
Firmware updates are separate from routine rebooting. Many routers automatically restart when a firmware installation is completed, so owners should use the manufacturer’s update controls or automatic-update feature rather than relying on a manual reboot to install new software.
Reboot or factory reset?
A reboot is not the same as a factory reset, and confusing the two can create unnecessary headaches.
A reboot simply restarts the equipment, while preserving the network configuration already stored on the router.
A factory reset erases configuration such as the Wi-Fi name, password, port-forwarding rules, and other customized settings. It should generally be reserved for serious troubleshooting, setup problems, or preparing equipment for another owner.
For routine maintenance, use the router’s restart option or perform a normal power cycle. There is no reason to erase carefully configured settings simply because the network has become temporarily sluggish.
How should you reboot your router?
If a separate modem and router are installed, power both devices down and follow the manufacturer’s recommended waiting period. Guidance varies by equipment, ranging from about 30 seconds for some router-only restarts to several minutes when power-cycling an entire modem-and-router setup.
Turn the modem back on first and wait until it has fully re-established its connection with the internet provider. Then turn on the router and allow it to finish starting before testing Wi-Fi or wired connections.
Some routers include scheduled-reboot controls in their apps or web interfaces. When available, scheduling the restart during an overnight period when the network is not being used can reduce disruption.

When should you reboot more often?
NSA recommends at least weekly home-router reboots as a security measure. A reboot can also be useful when a network develops temporary symptoms such as unexplained slowdowns, dropped connections or devices that fail to reconnect.
After an ISP outage or maintenance event, restarting the modem or router can help if connectivity does not return normally. Firmware updates commonly restart the router themselves, so another reboot is usually unnecessary unless the manufacturer instructs otherwise.
Frequent restarting should not become the permanent solution to recurring failures. If a router needs attention every few days, check for firmware problems, overheating, power issues, ISP faults or failing hardware.
Frequent reboots may signal replacement time
A router that repeatedly becomes unstable may have insufficient hardware resources, buggy or outdated firmware, overheating, power problems or another underlying fault. Rebooting can temporarily clear symptoms without correcting the root cause.
End-of-support hardware creates a separate security concern because manufacturers stop issuing firmware fixes. A router that no longer receives security updates should be considered for replacement even if it still appears to work normally.
Four to five years is a useful checkpoint for reviewing a router’s support status and performance, not a fixed expiration date. Replace sooner when security support ends or persistent faults remain after troubleshooting.
Little-known fact: An FBI alert found routers from 2010 or earlier are being actively hijacked by malware that exploits their lack of security patches.
Better Wi-Fi maintenance starts elsewhere too
Rebooting is useful, but it should complement stronger security practices rather than replace them. Automatic firmware updates should be enabled when available, and remote administration from the public internet should generally remain disabled.
Strong, unique Wi-Fi credentials also reduce unnecessary security exposure. Keeping old routers indefinitely because they still produce a signal can be a false economy when important security patches are no longer available.
For smart-home owners, the best routine is straightforward: maintain current firmware, schedule a weekly reboot when practical, monitor recurring symptoms, and replace unsupported equipment. A reboot should improve a healthy network, not conceal a failing one.

TL;DR
- NSA recommends rebooting home routing devices at least weekly as part of its home-network security guidance.
- Rebooting can clear volatile memory and temporary software or connection state, but recurring instability should be investigated rather than managed indefinitely with restarts.
- A normal reboot preserves Wi-Fi settings, while a factory reset erases configuration and should be reserved for serious troubleshooting or ownership changes.
- When a modem and router are separate, bring the modem online first and wait for its connection to stabilize before restarting the router.
- Router security also depends on current firmware, strong credentials, disabled internet-facing remote administration and replacing equipment that no longer receives security updates.
