Regular router reboots recommended for speed and security, Engadget says
FBI and NSA recommend regular router reboots to maintain speed, security and stability, Engadget reports.
A router is a small computer that runs around the clock, handling a huge amount of data for every device in your household, from phones and laptops to smart TVs and thermostats. Over time, its memory fills with temporary files and caches, causing slower speeds, dropped connections and buffering. Rebooting once a month gives the router a fresh start and helps clear those issues. It also makes the router rescan Wi-Fi channels and select less crowded options, which can improve wireless performance.
Security is another reason to make rebooting a monthly habit. Engadget notes that the FBI advises users to restart their router when they notice anything suspicious, while the NSA suggests scheduling a weekly reboot for all internet-connected devices, including routers, smartphones and computers. A reboot restarts security processes and can wipe away suspicious temporary connections that attackers might exploit.
The process takes about two minutes and requires no technical knowledge. Unplug the router for 30 seconds to a minute, then plug it back in. If you have a separate modem, unplug both, connect the modem first, wait a minute, then restore the router. Some routers have a physical power switch, but unplugging is the best way to perform a full reboot. If the router's power outlet is hard to reach, a smart plug can let you cut and restore power from an app.
Many modern routers allow you to schedule automatic reboots through their settings or companion apps. This lets the device refresh itself overnight when you are not using the internet. Turning on automatic firmware updates is also recommended, as this installs security patches and bug fixes without manual effort. If your router lacks these options, set a recurring monthly reminder on your phone.
Rebooting is different from resetting. A reboot turns the device off and on while keeping all your settings. A factory reset, however, wipes everything back to the original defaults, including the network name and password. Only do a factory reset during major troubleshooting or before giving the router away.
Signs that your router may need a reboot include slower-than-usual internet speeds, spotty Wi-Fi that regularly disconnects, devices falling off the network, or consistent buffering during streaming or downloads. If those problems persist even after a reboot, you may need to consider a mesh Wi-Fi system or range extenders for better coverage.
