The NetMirror app has gained popularity for its seamless screen mirroring capabilities, often used in both personal and professional settings. However, like any technology, it can sometimes stop working as expected. When this happens, users often feel frustrated, especially if they’re relying on the app for a meeting, presentation, or entertainment. In this comprehensive troubleshooting guide, we’ll walk you through every step needed to identify and fix issues with the NetMirror app.
TL;DR: Quick Troubleshooting Overview
If the NetMirror app isn’t working, start by checking your internet connection and ensuring both devices are on the same network. Restart both your phone and the receiving device. Make sure the app and your OS are updated to the latest versions. If the problem persists, try clearing the app cache or reinstalling the app entirely.
1. Confirm Your Network Connection
NetMirror works over Wi-Fi, so the first thing to verify is that both the source (e.g., your phone or tablet) and the target device (smart TV, computer) are connected to the same Wi-Fi network.
- Open Wi-Fi settings on both devices.
- Ensure they are connected to the same SSID (network name).
- Avoid using mobile data or VPNs during mirroring.
Having the devices on separate networks or behind firewalls can disrupt the app’s connectivity. This is a common oversight that can be fixed in under a minute.
2. Restart All Devices
As basic as it sounds, restarting your devices can resolve many temporary glitches. This includes both your mobile device and the display device.
Steps to follow:
- Turn off your smartphone or tablet.
- Turn off the receiving device (TV/computer).
- Unplug your router for 30 seconds, then plug it back in.
- Power everything back on and test the connection again.
This refreshes the network environment and clears any temporary cache that could interfere with the communication process.
3. Check App and System Updates
Outdated software is a frequent culprit when screen mirroring apps like NetMirror fail to function properly. Make sure you update both the app and your operating systems.
- Go to your device’s app store.
- Search for “NetMirror” and tap Update if available.
- Check for device software updates in system settings.
Be aware that system updates sometimes introduce new security settings or permissions that may restrict casting or network access. This is particularly common with iOS and Android security patches.
4. Grant Necessary Permissions
Like many apps, NetMirror requires specific permissions to access network data, screen content, and other resources. If these permissions are restricted or not granted, the app may not function correctly.
Check permissions on Android:
- Go to Settings > Apps > NetMirror
- Select Permissions
- Allow access to all necessary features, particularly Network, Display, and Storage
Check permissions on iOS:
- Go to Settings > NetMirror
- Enable all required access toggles
After adjusting permissions, restart the app to try again.
5. Enable Screen Mirroring Feature on TV or Receiver
Not all smart devices have screen mirroring enabled by default. Make sure this feature is turned on in your receiving hardware.
For Smart TVs:
- Navigate to Settings > Network or Display
- Enable options such as Screen Mirroring, Wireless Display, or Miracast
For PCs as receivers:
- Ensure both devices support Miracast or use NetMirror’s desktop receiver app
- Start the app before you begin screen casting from the mobile device
6. Clear App Cache and Data
Over time, app cache and temporary data can become corrupted and interfere with performance. Clearing this can reset the app without affecting your saved data on the cloud.
For Android:
- Go to Settings > Apps > NetMirror
- Tap on Storage
- Select Clear Cache, then Clear Data
For iOS:
- iOS doesn’t allow cache clearing directly. You’ll need to uninstall and reinstall the app:
- Tap and hold the app icon > Select Delete
- Download it again from the App Store
7. Check for External Interference
Sometimes the issue isn’t the app—it’s the environment. Certain network configurations, appliances, or physical barriers can interfere with Wi-Fi signals and reduce connectivity quality.
- Move both devices closer to the router
- Ensure walls, microwaves, or other electronics aren’t blocking the signal path
- Switch to the 5GHz Wi-Fi band if possible for better speed and lower interference
8. Reinstall the NetMirror App
If clearing cache doesn’t help, a clean reinstall may fix persistent issues caused by corrupted installation files or configuration problems.
Steps:
- Uninstall NetMirror from your device
- Restart the device
- Re-download the app from your official app store
- Open the app and grant all permissions when prompted
After reinstalling, test it again while ensuring both devices are on the same Wi-Fi network.
9. Contact Support
If none of the above steps work, the issue might be device-specific or related to your account. NetMirror offers dedicated customer support to help resolve such problems.
You can reach out through the following channels:
- In-app support: Navigate to Help or Feedback within the app

Conclusion
NetMirror is a powerful tool when it works—but when it doesn’t, it can bring productivity and entertainment to a halt. The good news is that most issues are easily resolvable with basic troubleshooting steps like checking your network, restarting devices, updating apps, and verifying permissions. By systematically following this guide, you’ll likely be back to screen mirroring in no time. For more advanced or unique errors, always reach out to official support channels for assistance.
