Restarting your router clears its temporary memory, drops and re-establishes the connection to your provider, and reloads its settings. This fixes many common problems like slow speeds, dropped connections, and devices that will not get online. Your Wi-Fi name, password, and settings are kept, because a restart is not a reset. Expect the internet to be down for about one to five minutes while it reconnects.
Why this happens
A router is a small computer that runs constantly. Over time its memory can fill, its connection to the provider can get stuck, and minor software glitches build up.
Restarting clears the memory, forces a fresh connection to your provider, and reloads a clean copy of the settings, which resolves many temporary faults.
Is this normal?
Yes. Restarting the router is the single most common home network fix and is completely safe to do as often as needed.
Does it cause any problems?
The only effect is a short internet outage while it reboots, usually one to five minutes. Your settings are not lost, and a restart does not erase anything.
How to fix or check it
- Use the power button if it has one, or unplug the power cable.
- Wait about thirty seconds so the device fully powers down and clears memory.
- Plug it back in and wait until the status lights return to normal, which can take a few minutes.
- If you have a separate modem, restart the modem first, wait for it to come online, then restart the router.
- Reconnect a device and test the connection.
Frequently asked questions
Is restarting the same as resetting the router?
No. A restart just reboots it and keeps all settings. A reset erases everything and returns it to factory defaults.
How often should I restart my router?
Only when you have a problem, though an occasional restart, such as once a month, can help keep a busy home network running smoothly.
Will restarting change my Wi-Fi password?
No. Your network name and password stay the same. Only a factory reset changes those back to the defaults.
