- \n
- Open Wi-Fi settings on both devices.<\/li>\n
- Ensure they are connected to the same SSID (network name).<\/li>\n
- Avoid using mobile data or VPNs during mirroring.<\/li>\n<\/ul>\n
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.<\/p>\n
2. Restart All Devices<\/h2>\n
As basic as it sounds, restarting your devices<\/strong> can resolve many temporary glitches. This includes both your mobile device and the display device.<\/p>\n
Steps to follow:<\/p>\n
- \n
- Turn off your smartphone or tablet.<\/li>\n
- Turn off the receiving device (TV\/computer).<\/li>\n
- Unplug your router for 30 seconds, then plug it back in.<\/li>\n
- Power everything back on and test the connection again.<\/li>\n<\/ul>\n
This refreshes the network environment and clears any temporary cache that could interfere with the communication process.<\/p>\n
3. Check App and System Updates<\/h2>\n
Outdated software is a frequent culprit<\/strong> when screen mirroring apps like NetMirror fail to function properly. Make sure you update both the app and your operating systems.<\/p>\n
- \n
- Go to your device’s app store.<\/li>\n
- Search for “NetMirror” and tap Update<\/em> if available.<\/li>\n
- Check for device software updates in system settings.<\/li>\n<\/ol>\n
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.<\/p>\n
4. Grant Necessary Permissions<\/h2>\n
Like many apps, NetMirror requires specific permissions<\/strong> to access network data, screen content, and other resources. If these permissions are restricted or not granted, the app may not function correctly.<\/p>\n
Check permissions on Android:<\/p>\n
- \n
- Go to Settings > Apps > NetMirror<\/em><\/li>\n
- Select Permissions<\/em><\/li>\n
- Allow access to all necessary features, particularly Network, Display, and Storage<\/strong><\/li>\n<\/ul>\n
Check permissions on iOS:<\/p>\n
- \n
- Go to Settings > NetMirror<\/em><\/li>\n
- Enable all required access toggles<\/li>\n<\/ul>\n
After adjusting permissions, restart the app to try again.<\/p>\n
5. Enable Screen Mirroring Feature on TV or Receiver<\/h2>\n
Not all smart devices have screen mirroring enabled by default. Make sure this feature is turned on in your receiving hardware.<\/p>\n
For Smart TVs:<\/p>\n
- \n
- Navigate to Settings > Network or Display<\/em><\/li>\n
- Enable options such as Screen Mirroring, Wireless Display, or Miracast<\/em><\/li>\n<\/ul>\n
For PCs as receivers:<\/p>\n
- \n
- Ensure both devices support Miracast or use NetMirror’s desktop receiver app<\/li>\n
- Start the app before you begin screen casting from the mobile device<\/li>\n<\/ul>\n

\n6. Clear App Cache and Data<\/h2>\n
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.<\/p>\n
For Android:<\/p>\n
- \n
- Go to Settings > Apps > NetMirror<\/em><\/li>\n
- Tap on Storage<\/em><\/li>\n
- Select Clear Cache<\/strong>, then Clear Data<\/strong><\/li>\n<\/ul>\n
For iOS:<\/p>\n
- \n
- iOS doesn’t allow cache clearing directly. You\u2019ll need to uninstall and reinstall the app:<\/li>\n
- Tap and hold the app icon > Select Delete<\/em><\/li>\n
- Download it again from the App Store<\/li>\n<\/ul>\n
7. Check for External Interference<\/h2>\n
Sometimes the issue isn\u2019t the app\u2014it\u2019s the environment. Certain network configurations, appliances, or physical barriers<\/strong> can interfere with Wi-Fi signals and reduce connectivity quality.<\/p>\n
- \n
- Move both devices closer to the router<\/li>\n
- Ensure walls, microwaves, or other electronics aren\u2019t blocking the signal path<\/li>\n
- Switch to the 5GHz Wi-Fi band if possible for better speed and lower interference<\/li>\n<\/ul>\n

\n8. Reinstall the NetMirror App<\/h2>\n
If clearing cache doesn\u2019t help, a clean reinstall may fix persistent issues caused by corrupted installation files or configuration problems.<\/p>\n
Steps:<\/p>\n
- \n
- Uninstall NetMirror from your device<\/li>\n
- Restart the device<\/li>\n
- Re-download the app from your official app store<\/li>\n
- Open the app and grant all permissions when prompted<\/li>\n<\/ul>\n
After reinstalling, test it again while ensuring both devices are on the same Wi-Fi network.<\/p>\n
