To resolve the issue of the Collectr app stating there is no Wi-Fi connection, even while positioned next to your modem and having mobile data enabled, follow these step-by-step instructions:

1. Check Your Wi-Fi Status:
- Ensure your device is actually connected to the Wi-Fi network. Go to your device's Settings > Network & internet > Wi-Fi and confirm that the network is shown as connected.

2. Toggle Airplane Mode:
- Activate and deactivate Airplane mode. This can refresh your device's network connections and might help the app recognize the Wi-Fi connection. Navigate to Settings > Network & internet > Airplane mode.

3. Restart Your Modem and Router:
- Power cycle your modem and router. Unplug them from the power source, wait for about 10 seconds, and then plug them back in. This can resolve many connectivity issues by refreshing the internet connection.

4. Restart the Collectr App:
- Completely quit the app. For Android, tap the square app icon (recent apps button), and swipe up on the Collectr app to close it. Then reopen the app.

5. Check for App Updates or Reinstall:
- Ensure you have the latest version of the Collectr app. Go to the Google Play Store, search for Collectr, and check for any available updates. If problems persist, consider uninstalling and reinstalling the app.

6. Reset Network Settings:
- Consider resetting your network settings. Go to Settings > System > Reset options > Reset Wi-Fi, mobile & Bluetooth. This will clear all saved networks, so you'll need to reconnect to your Wi-Fi afterward.

7. Check for Background Data Restrictions:
- Ensure that the app is allowed to use data in the background. Navigate to Settings > Apps > Collectr > Mobile data & Wi-Fi, and ensure that any restrictions are disabled.

8. Test with Other Apps:
- Verify if the issue is specific to Collectr by testing other apps that require internet access. If those work fine on Wi-Fi, the problem might be with the Collectr app itself.

9. Contact Support:
- If the problem continues after trying the steps above, reach out to
