How often should you actually restart your router?

A restart every few weeks, or whenever performance genuinely feels off, is the sensible middle ground, not never and not daily. Routers do benefit from occasional restarts, but not for the reasons or frequency most people assume, and needing to restart much more often than that is usually a sign of an underlying problem, not normal router behavior.
Why restarting occasionally helps
Routers accumulate memory usage and minor glitches over long uptime, similar to any always-on device, and clear these with a restart. It also lets the router reapply the latest firmware if an update was downloaded but not yet installed, many routers download updates in the background but wait for a restart to actually apply them.
Why daily restarts aren't necessary
A well-functioning router with decent hardware and updated firmware can comfortably run for weeks without issue. Restarting daily is unnecessary and, if the network briefly drops during the reboot, more disruptive than helpful, especially inconvenient if it happens to interrupt something in progress like a video call or download.
When frequent restarts are actually masking a real problem
If you find yourself needing to restart the router every few days just to keep things working, that's not normal router behavior, it's a sign of an underlying issue, aging hardware, a specific device causing repeated conflicts, or outdated firmware, that a restart is only temporarily papering over rather than actually fixing.
Our practical recommendation
"A restart every few weeks, or whenever performance genuinely feels off, is a reasonable middle ground. If you're restarting more often than that just to keep things working, that's usually a sign of an underlying issue worth diagnosing properly instead of treating a frequent restart as the actual solution," says Mustafa Husain, Founder of SAS4HomeIT.

- Firmware
- The built-in software that runs a router's hardware; updates are often downloaded automatically in the background but only take effect after a restart.

Why does restarting a router actually help?

Is it normal to need to restart my router every few days?
No, needing to restart every few days just to keep things working is a sign of an underlying issue, like aging hardware, a specific device causing conflicts, or outdated firmware, that a restart is only temporarily masking rather than fixing.
