Clear your Eero cache through the mobile app or by restarting the device

The fastest way to clear cache on an Eero router is to restart it through the Eero app. Open the app, tap the three-line menu, select your router, tap the three dots in the top right, and choose "Restart." The router will power down, clear its temporary memory, and restart — the whole process takes about five minutes. If you do not have the app handy, you can also unplug the router for 30 seconds and plug it back in, which accomplishes the same thing.

Clearing cache can help if your router is running slowly, if you are having trouble connecting to certain websites, or if you want to reset stored network information without losing your Wi-Fi password or other settings. It does not delete your network name, password, or any configuration you have set up — it only clears the temporary data the router uses while it is running.

Key Takeaways

  • The Eero app method (Menu > Your Router > Settings > Restart) is the cleanest way to clear cache and takes about five minutes.
  • Unplugging the router for 30 seconds and plugging it back in does the same thing if you do not have the app available.
  • Clearing cache does not erase your Wi-Fi password, network name, or any settings you have configured.
  • A cache clear can fix slow speeds or connection problems to specific websites without requiring you to set up your network again.

Using the Eero app to restart your router

Open the Eero app on your phone and tap the three horizontal lines (the menu icon) at the bottom left. Find your router in the list — if you have multiple Eero devices, select the main router, not a beacon or extender. Tap on it to open the device details page.

At the top right of the device details page, tap the three vertical dots (the options menu). Scroll down and select "Restart." The app will ask you to confirm. Tap "Restart" again. Your router will shut down, and you will see a message saying it is restarting. Wait about five minutes for the lights to return to normal and for your Wi-Fi to come back online. Once the app shows your router as online again, the cache has been cleared.

Restarting the router manually without the app

If you do not have the Eero app or prefer not to use it, you can restart the router by unplugging it. Locate the power cable at the back of the router and pull it out of the outlet. Wait 30 seconds — this gives the router time to fully power down and clear its memory.

After 30 seconds, plug the power cable back in. The router will start up, and you will see the lights begin to flash. Wait about five minutes for the startup sequence to complete. When the lights settle into a steady pattern and your Wi-Fi network appears in your device's network list, the restart is done and the cache has been cleared.

What gets cleared and what stays

When you restart your Eero router, it clears the cache — temporary data the router stores while running, such as recently visited websites, DNS lookups, and connection logs. This temporary memory helps the router work faster, but it can sometimes cause problems if it becomes corrupted or outdated.

Restarting does not erase your Wi-Fi network name, password, or any settings you have configured in the Eero app. Your network will come back online with the same name and password after the restart. Any port forwarding, parental controls, or other custom settings you have set up will remain in place.

When to clear your router's cache

Clear your Eero cache if your router is running slowly, if you are experiencing lag when browsing or streaming, or if you cannot reach a specific website even though your internet connection is working. A cache clear can also help if you recently changed your internet service provider or modem and your router is having trouble connecting to the new setup.

You do not need to clear the cache regularly — most routers manage this on their own. A manual cache clear is a troubleshooting step, not a maintenance task you should do weekly or monthly. If clearing the cache does not fix your problem, the issue may be with your internet connection, your modem, or a specific device rather than the router itself.

Difference between restarting and factory resetting

A restart (what you do to clear cache) is different from a factory reset. A restart clears temporary memory and brings the router back online with all your settings intact. A factory reset erases everything — your Wi-Fi password, network name, and all custom settings — and returns the router to the state it was in when you first unboxed it.

You should only factory reset if you are troubleshooting a serious problem, planning to give away or sell the router, or if Eero support specifically tells you to do so. For everyday problems like slow speeds or connection issues, a restart is the right move.

Frequently Asked Questions

How long does it take for the router to come back online after a restart?

Most Eero routers take about five minutes to fully restart and reconnect. The lights will flash during startup and then settle into a steady pattern once the router is ready. Your Wi-Fi network should appear in your device's network list within this time.

Will I lose my Wi-Fi password if I restart the router?

No. Restarting only clears temporary cache, not your saved settings. Your Wi-Fi network name and password will be exactly the same after the restart, and your devices should reconnect automatically if they were connected before.

What if my router does not come back online after I restart it?

Wait a full ten minutes — sometimes the startup takes longer than expected. If the router still does not come online, unplug it again for 30 seconds and plug it back in. If it still will not start after a second restart, contact Eero support, as this may indicate a hardware problem.

Can I restart just one Eero beacon or do I have to restart the main router?

You can restart individual beacons or extenders through the app if you want to clear cache on just one device. However, if you are troubleshooting a connection problem, restart the main router first — that is where most of the cache that affects your network lives.

Is there a way to schedule automatic cache clears?

Eero does not offer a built-in scheduling feature for automatic restarts. You can only restart manually through the app or by unplugging the device. Some users restart their routers monthly as preventive maintenance, but it is not required.
