Clear Cache on eero Router Easily | Improve Wi-Fi Performance Now
Modern Wi-Fi networks rely on temporary memory to speed up internet browsing and maintain smooth device connections. Your eero router, like many mesh Wi-Fi systems, uses a cache to store frequently accessed network information, including IP addresses, DNS queries, and device routing paths. Over time, this cache can become cluttered with outdated or incorrect data. When that happens, your network might slow down, devices may disconnect, or websites may fail to load.
Clearing this cache is often the simplest way to refresh your network. By doing so, you help your eero gateway and mesh nodes operate efficiently, improve Wi-Fi stability, and prevent common connectivity issues.
In this guide, we will explain everything from power cycles to soft and hard resets, show how to manage your network through the eero app, and share best practices for cache maintenance and DNS optimization.
What Does “Clearing Cache” Mean on an eero Router?
Your eero router cache acts like a temporary notebook. It stores small bits of information to speed up network responses. Examples include:
- Recently visited IP addresses
- DNS lookups for websites
- Routing paths between devices
While this speeds up routine traffic, cached data can sometimes include errors. These errors may result in:
- Slow website loading
- Network disconnections
- Devices failing to connect or reconnect
In addition, clearing cache helps when implementing Warmup Cache Request techniques or applying Cache Warming Strategies for Modern Web Apps, which can ensure smoother data retrieval across your home network.
Signs You May Need to Clear Cache on Your eero Router
You might consider clearing your eero cache if you notice any of the following:
- Wi-Fi is slower than usual
- Specific websites or apps fail to load
- Devices disconnect randomly
- Streaming or gaming is lagging
- Your network is congested during peak hours
How to Clear Cache on eero Router: The Quickest Method
The most straightforward method is a power cycle, which effectively clears temporary data and rebuilds cache.
Steps:
- Unplug your eero device from the power outlet.
- Wait 30 seconds.
- Plug it back in.
- Wait up to 3 minutes for the LED indicators to stabilize.
Tips:
- Start with your gateway eero first, then move to other mesh nodes.
- Ensure your modem is fully online before restarting other devices.
- This process is safe and does not delete your network settings.
Clearing Cache via the eero App
The eero app allows you to manage your network and restart devices without physically unplugging them.
Steps:
- Open the eero App on your smartphone.
- Tap the eero device you want to restart.
- Select More Options → Restart.
- For a full network restart, go to Settings → Advanced Networking → Restart Network.
Advantages of using the app:
- No need to physically access your devices.
- Ensures all firmware updates are applied during restart.
- Maintains logs, IP reservations, and device configurations.
Soft Reset vs Hard Reset: What You Need to Know
Understanding the difference between resets is crucial:
| Reset Type | What It Does | When to Use | LED Indicator |
|---|---|---|---|
| Soft Reset | Reboots device, clears temporary cache, resets Wi-Fi channel | Minor issues, cache rebuild | Yellow flashing |
| Hard Reset | Factory reset, deletes all settings and user data | Severe network issues or selling device | Red flashing, then Blue ready |
Key Notes:
- Always start with a soft reset before performing a hard reset.
- Soft resets rebuild caches without erasing routing tables or reserved IPs.
- Hard resets are irreversible; only use when necessary.
Step-by-Step Guide: Soft Reset on eero Router
- Locate the reset button on your eero device.
- Hold the button until the LED flashes yellow (approx. 7–8 seconds).
- Release the button and allow the gateway to fully restart.
- Restart additional leaf nodes one by one.
- Verify connectivity via the eero app.
Tips:
- Always start with your main gateway eero.
- Wait for solid white LED before resetting other nodes.
- Avoid pressing the button too long, as it may trigger a hard reset.
Hard Reset: Step-by-Step Guide for eero Routers
A hard reset is a factory reset that deletes all settings, logs, and saved configurations. Only use this when troubleshooting severe issues or when setting up a new network.
Steps:
- Locate the reset button on the bottom or back of your eero device.
- Hold the button for approximately 15 seconds until the LED flashes red.
- Release the button. The LED will flash white during boot-up, then blue when ready for setup.
- Open the eero app and follow the on-screen instructions to add your device back to the network.
Important Notes:
- Hard reset will remove reserved IPs, port forwarding rules, and Wi-Fi passwords.
- Only use manual serial number entry in the app if prompted.
- Ensure your modem and internet connection are stable before setting up the eero again.
Troubleshooting Common eero Router Issues
Even after clearing cache or resetting, some issues may persist. Here’s how to fix them:
1. Slow Wi-Fi or Connection Drops
- Ensure eero devices are within 50 feet of each other.
- Avoid interference from metal objects, mirrors, thick walls, or microwaves.
- Restart gateway first, then other nodes.
2. Devices Not Reconnecting
- Check if your device is connected to the correct Wi-Fi network.
- Remove old networks and reconnect via the eero app.
- Power cycle both the modem and eero devices.
3. Firmware or App Issues
- Update the eero firmware via the app.
- Ensure the eero app is the latest version for your OS (iOS/Android).
- Restart the app after firmware updates.
4. DNS Issues
- If websites don’t load, the problem may be a DNS cache.
- Consider flushing DNS on your computer or mobile device (Windows/macOS/Android/iOS).
Flushing DNS Cache on Your Devices
While this is separate from clearing the router cache, it complements the cache refresh process.
| Device | Command / Method | Notes |
|---|---|---|
| Windows | ipconfig /flushdns | Run in Command Prompt as administrator |
| macOS | sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder | Use Terminal, varies by macOS version |
| iOS | Toggle Airplane Mode on/off or reboot device | Clears device-level DNS cache |
| Android | Reboot or toggle Airplane Mode | Device-level DNS cache cleared |
Placement & Network Optimization Tips
Your eero cache performs best when devices are placed strategically. Use these guidelines:
- Place the gateway eero in a central location.
- Avoid floors or enclosed spaces; shelves or open tables work best.
- Keep mesh nodes within 50 feet of the gateway or adjacent nodes.
- Minimize interference from large electronics, thick walls, or metallic objects.
Tip: Regular restarts using Warmup Cache Request and Cache Warming Strategies for Modern Web Apps can keep your network consistently fast.

FAQs
1. What is the easiest way to clear cache on an eero router?
The fastest method is a power cycle: unplug your eero device for 30 seconds, then plug it back in. This clears temporary memory without affecting your settings.
2. How often should I clear my eero cache?
A soft reset or power cycle every 2–3 weeks is recommended. For heavy network usage, weekly restarts can improve stability.
3. What is the difference between soft and hard reset?
A soft reset refreshes your router and clears temporary cache, keeping network settings intact. A hard reset wipes all settings, user data, and requires reconfiguration via the eero app.
4. Can I clear cache using the eero app?
Yes. Open the app → tap your device → More Options → Restart. For the entire network, go to Settings → Advanced Networking → Restart Network.
5. My eero nodes won’t reconnect after reset. What should I do?
- Start with the gateway eero first.
- Wait until the LED shows solid white.
- Restart other mesh nodes one by one.
- Ensure devices are within 50 feet of each other.
6. Does clearing eero cache affect my Wi-Fi password?
No. Power cycles and soft resets do not remove passwords. Only a hard reset deletes Wi-Fi settings.
7. How do I perform a hard reset on eero?
Hold the reset button for ~15 seconds until the LED flashes red. Release and follow the eero app instructions to set up the device again.
8. How can I fix slow website loading after clearing cache?
- Check DNS settings on your device.
