When a phone, computer, or tablet shows the “No nearby devices found” error while trying to cast, it usually means the devices can’t see each other on the network. The fastest fix is to make sure both the casting device and the Chromecast or smart TV are on the same Wi-Fi network and powered on. This single step solves most connection issues.

Sometimes the problem goes further than Wi-Fi. Network discovery might be disabled, the Google Home app may need an update, or a router setting could be blocking connections. Restarting the router, the Chromecast, and the casting device often clears these conflicts.

If the issue continues, it may involve permissions or outdated software. Checking app permissions, updating firmware, or resetting the Chromecast can restore casting. These steps ensure devices connect smoothly for casting media or screen mirroring without constant errors.

1. Check the Basics First

  • ✅ Make sure your TV and Chromecast (or Google TV device) are turned on.
  • ✅ Confirm the Chromecast is plugged in properly and the TV is set to the correct HDMI input.
  • ✅ Ensure your phone, tablet, or PC is connected to the same Wi‑Fi network as your Chromecast.

2. Restart Devices

  • Restart your phone or computer.
  • Restart your Chromecast/Google TV by unplugging it for 30 seconds and plugging it back in.
  • Restart your Wi‑Fi router to clear network glitches.

3. Verify Network Settings

  • Open your Wi‑Fi settings and confirm both devices are on the same band (2.4 GHz or 5 GHz).
  • If your router has AP Isolation (Client Isolation) enabled, turn it off — this feature prevents devices from communicating.
  • If using a VPN, disable it temporarily, as it can block casting.

4. Update Software

  • Update the Google Home app on your phone.
  • Update your Chromecast firmware (done automatically, but only if it’s online).
  • Update your browser (if casting from Chrome).

5. Re‑Add Chromecast in Google Home

If the device still doesn’t show:

  1. Open the Google Home app.
  2. Tap + → Set up device → New device.
  3. Follow the prompts to reconnect Chromecast to your Wi‑Fi.

6. Check Permissions (Mobile Devices)

  • On Android, ensure the Google Home app has Location permissions enabled.
  • On iPhone/iPad, allow Local Network Access for Google Home (Settings → Privacy → Local Network).

7. Advanced Fixes

  • Factory reset Chromecast: Press and hold the button on the Chromecast until the LED light flashes, then re‑set it up in Google Home.
  • Try another device: If your phone can’t find it, try casting from a laptop or another phone to rule out device‑specific issues.
  • Check router firmware: Outdated router firmware can cause discovery issues.

8. When to Contact Support

If none of the above works, the issue may be hardware‑related. You can contact Google Chromecast Support or your router manufacturer for deeper troubleshooting.

✅ Quick Recap

  • Ensure all devices are on the same Wi‑Fi.
  • Restart Chromecast, router, and phone.
  • Update Google Home and Chrome.
  • Re‑add or factory reset Chromecast if needed.
  • Check permissions (Location / Local Network).

Key Takeaways

  • Casting fails when devices are not on the same Wi-Fi network
  • Restarting devices and checking network discovery often solves issues
  • Updates or permissions may be required for stable casting

Frequently Asked Questions

Casting errors often come from network issues, device settings, or software conflicts. Fixes usually involve checking Wi-Fi connections, restarting devices, and adjusting permissions for casting or Bluetooth.

Why am I getting a ‘No nearby devices found’ error when trying to cast on my Android device?

This error often happens when the phone and the cast device are not on the same Wi-Fi network. It can also occur if network discovery is off or if the cast device is not powered on. Restarting both devices usually helps.

What steps can I take to troubleshoot a Pixel device that isn’t detecting nearby devices for casting?

First, confirm that the Pixel is on the same Wi-Fi as the target device. Then check if the Google Home app recognizes the cast device. If not, restart the Pixel and router, and update system software.

How can I resolve casting issues on my Samsung device when it fails to find nearby devices?

Samsung phones may block casting if permissions are disabled. Enable Smart View or SmartThings and make sure the device has location and network permissions. Restarting the phone and cast device often clears the issue.

What should I do if my device says ‘No nearby devices were found’ while attempting to use Bluetooth casting?

Check that Bluetooth is turned on and the other device is in pairing mode. Remove old pairings that may cause conflicts. If the error continues, reset Bluetooth settings and try again.

Is there a way to fix casting problems on Roku when it cannot detect nearby devices?

Ensure the Roku and the phone are on the same Wi-Fi band, either 2.4 GHz or 5 GHz. Restart the Roku and mobile device, then open the casting app again. Updating Roku software can also fix detection issues.

Why does my device fail to cast to nearby devices even though they are in range and casting is enabled?

Firewall or antivirus settings can block casting traffic. Network isolation features on routers may also prevent devices from seeing each other. Disabling those settings or adjusting router controls usually resolves the problem.
