Why you might need to clear your Eero's cache
Your Eero router stores temporary data about the websites you visit, the devices on your network, and how traffic moves between them. This cache usually speeds things up — your router doesn't have to look up the same information twice. But sometimes that stored data gets corrupted, outdated, or just too full, and clearing it fixes connection drops, slow speeds, or devices that won't connect.
You don't need to clear cache often. Most people never do. But if you've restarted your router and the problem persists, or if you're troubleshooting a specific device that won't join your network, clearing the cache is a straightforward next step that takes less than five minutes.
Key Takeaways
- Clearing cache on an Eero router means resetting the temporary data it stores, which can fix connection problems without erasing your passwords or network name.
- You can clear cache through the Eero app by going to Settings, selecting your router, and choosing the cache-clearing option — the exact menu name depends on your Eero model and app version.
- A full factory reset erases everything including your network name and passwords, so use the cache-clear option instead unless you're selling the router or starting completely fresh.
- After clearing cache, reconnect your devices to the network using your existing password — they won't automatically rejoin.
How to clear cache through the Eero app
Open the Eero app on your phone and tap the menu icon (three horizontal lines) in the bottom right corner. Select Settings, then tap the name of your router or the specific Eero device you want to clear. Scroll down until you see an option labeled Clear Cache, Restart, or Reboot — the exact wording varies depending on your Eero model and which app version you have installed.
Tap that option and confirm when the app asks you to verify. The router will restart, which takes about two to three minutes. You'll see a loading screen in the app. Don't unplug the router during this time. Once the light on the device turns solid green again, the cache is cleared and you're ready to reconnect your devices.
If you can't find the cache-clearing option in your app, check that you're running the latest version. Open your phone's app store, search for Eero, and install any available updates. The menu layout sometimes changes between versions, and an older app might not show the option at all.
Clearing cache by restarting your router manually
If the app isn't working or you prefer not to use it, you can restart your Eero router the old-fashioned way. Unplug the power cable from the back of the device, wait 30 seconds, and plug it back in. The router will restart and clear its cache in the process.
This method clears the cache but doesn't erase your network name, password, or any settings you've configured. It's gentler than a factory reset and works just as well for most cache-related problems. The restart takes about three to five minutes, and you'll know it's done when the light on the front of the device turns solid green.
The difference between clearing cache and a factory reset
Clearing cache removes only the temporary data your router has collected while running. Your network name (SSID), password, and any custom settings you've made stay in place. After clearing cache, your devices will still remember your network and should reconnect automatically — though sometimes you need to manually reconnect them.
A factory reset erases everything: your network name, password, port forwarding rules, and any other configuration. You'd have to set up your Eero from scratch as if it were brand new. Only do a factory reset if you're selling the router, giving it away, or if clearing cache didn't solve your problem and you want to start completely fresh. To factory reset, hold the reset button on the back of the Eero device for 10 seconds until the light blinks orange.
What to do after clearing cache
Once your router has restarted and the light is solid green, your network is back online. Most of your devices will reconnect automatically using the password they already have stored. Check your phone, laptop, and any smart home devices to make sure they're connected.
If a device doesn't reconnect automatically, forget the network on that device and rejoin it manually. On an iPhone, go to Settings > Wi-Fi, tap the network name, and select Forget This Network. Then tap the network name again and enter your password. On Android, long-press the network name in your Wi-Fi list and select Forget, then rejoin the same way.
When clearing cache doesn't fix the problem
If you've cleared the cache and your connection is still dropping or devices still won't connect, the issue is probably something else. Check that your router is in a central location away from thick walls and metal objects, and make sure it's not sitting on the floor or inside a cabinet — these things block the signal.
If the problem only happens with one device, restart that device instead of the router. If it happens across multiple devices, try moving closer to the router to see if it's a range issue. If clearing cache, restarting, and repositioning don't help, contact Eero support through the app — they can see your network's performance data and tell you whether the router itself is failing.
Frequently Asked Questions
Will clearing cache erase my Wi-Fi password?
No. Clearing cache only removes temporary data. Your network name and password stay exactly as they are. Your devices will still know the password and should reconnect automatically.
How often should I clear my Eero's cache?
Most people never need to. Clear it only when you're troubleshooting a specific problem like slow speeds or devices that won't connect. If you're clearing cache more than once a month, something else is probably wrong with your setup or hardware.
Does clearing cache make my router faster?
It can, but usually only if the cache was corrupted or full. A healthy cache actually helps your router work faster by storing information it uses frequently. Clearing it helps only when something has gone wrong.
What's the difference between clearing cache and unplugging the router?
They're essentially the same thing. Unplugging the router for 30 seconds clears the cache and restarts it. Using the app to clear cache does the same restart automatically. Both methods work equally well.
Can I clear cache on just one Eero device if I have a mesh system?
Yes. If you have multiple Eero devices working together, you can clear cache on individual devices through the app. Select the specific device in Settings and choose the cache-clear option. You don't have to restart the whole system.
