How Often Should You Restart a Router? The Correct Modem and Router Order
A healthy router should not require a scheduled reboot to stay usable. One controlled restart can clear temporary state, but frequent failures point to heat, firmware, power, radio congestion, hardware or ISP trouble.
When a restart is reasonable
A single reboot is useful after the router interface becomes unresponsive, DHCP or NAT state appears stuck, or the provider specifically asks for a power cycle. It can also complete a normal configuration change when the vendor documents that requirement.
Restarting does not repair weak coverage, an undersized router, damaged cable, recurring ISP congestion or failing power supply. If performance only recovers briefly, record how long the improvement lasts instead of scheduling daily reboots indefinitely.
Preserve evidence before power cycling
Photograph the modem or ONT and router lights, note the time, affected devices, wired versus Wi-Fi behavior and exact errors. If the management page is available, record WAN status, uptime, temperature or logs without exposing passwords or public addresses.
Check the provider's outage page and verify cables are seated without bending fiber. A red LOS light or failed cable registration usually needs the ISP; rebooting repeatedly can erase timing evidence and delay support.
Use the correct restart sequence
Shut down or disconnect the personal router first. Use the documented power switch or unplug the modem/gateway only if no update is running. Wait about 30 seconds unless the manufacturer or ISP specifies another interval.
Power the modem or fiber gateway first and wait until its online, PON or broadband indicator reaches the normal stable state; this may take several minutes. Then power the router and wait for WAN and Wi-Fi. Finally reconnect one test device before restoring the rest of the household load.
Know when not to unplug
Do not remove power while firmware is installing, lights show an active upgrade, the provider is provisioning service, or a factory reset is in progress. Interrupting these operations can corrupt firmware or leave service unregistered.
Avoid restarting medical, security, voice or work connectivity without an approved maintenance window and backup method. Internet-based emergency calling and alarms may be unavailable during the reboot; understand local service limitations.
Reboot is different from factory reset
A reboot retains normal settings. A factory reset erases Wi-Fi names, passwords, ISP authentication, port rules, parental controls and possibly voice or IPTV configuration. Do not press the recessed Reset button for routine troubleshooting.
Before any justified reset, export configuration if supported, record ISP details and confirm account access. Provider-managed equipment may need remote activation, so follow the ISP's exact instructions.
Find why the router needs repeated restarts
Check ventilation, power adapter specifications, firmware release notes, free memory, client count and whether failures affect Ethernet as well as Wi-Fi. Test with background uploads stopped and compare latency under load. Replace only after evidence identifies a device limit or hardware fault.
If the WAN drops while local Wi-Fi remains available, inspect modem lights and ISP logs. If Wi-Fi disappears but Ethernet remains healthy, focus on radio channels, firmware and hardware. If every function freezes, power or router stability is more likely.
Create a reliable maintenance routine
Keep firmware current through the official vendor or ISP channel, back up configuration after stable changes, protect equipment from heat and use a correctly rated power supply. Do not automate nightly reboots as a substitute for updates or capacity planning.
After a reboot, test wired and Wi-Fi download, upload, Ping and DNS, and confirm voice, TV, VPN or smart-home functions. Escalate with timestamps and recurrence intervals when failures return.
Frequently asked questions
Should I restart my router every day or week?
A stable router should not need it. Reboot for a specific fault or update, and investigate if routine restarts are required.
How long should a router stay unplugged?
About 30 seconds is common for a basic power cycle, but follow the manufacturer or ISP instructions for the device.
Which device should turn on first, modem or router?
Start the modem, cable gateway or fiber ONT first, wait for internet registration, then start the personal router.
Is pressing Reset the same as restarting?
No. Reset usually erases configuration, while a reboot simply restarts the device and retains settings.
After restarting, compare wired and Wi-Fi performance before reconnecting every device.
