If NetMirror isn’t working, you’re not alone. Many users occasionally experience problems such as the app refusing to open, failing to connect to their TV, endless loading screens, or videos that simply won’t play.

The good news is that most NetMirror issues can be fixed within a few minutes. In this guide, we’ll explain the most common causes and show you step-by-step solutions that actually work.

Why Is NetMirror Not Working?

Several different problems can prevent NetMirror from functioning correctly.

Common causes include:

• Weak or unstable Wi-Fi
• Phone and TV connected to different networks
• Outdated NetMirror version
• Temporary app bugs
• Unsupported device
• TV casting disabled
• VPN or firewall interference
• Cache corruption
• Permission issues
• Temporary server problems

Fortunately, most of these are easy to solve.

Fix 1: Check Your Wi-Fi Connection

NetMirror depends on a stable local network.

Before trying anything else:

• Make sure Wi-Fi is connected.
• Restart your router.
• Test another app to confirm internet access.
• Avoid public Wi-Fi whenever possible.

For screen mirroring, both devices should have a strong signal.

Fix 2: Make Sure Both Devices Are on the Same Network

This is the most common reason NetMirror cannot detect a TV.

Your:

• Android phone
• iPhone
• Smart TV
• TV Stick

must all connect to the exact same Wi-Fi network.

If one device uses:

• Mobile data
• Guest Wi-Fi
• Another router
• VPN network

NetMirror may never discover your TV.

Fix 3: Restart Both Devices

Sometimes the simplest solution works best.

Restart:

• Your phone
• Your TV
• Your streaming device
• Your Wi-Fi router

Then reopen NetMirror.

This clears temporary network errors and refreshes the connection.

Fix 4: Update NetMirror

Older versions occasionally stop working after system updates.

Install the newest version of NetMirror.

Updating often fixes:

• App crashes
• Black screens
• Connection failures
• Compatibility issues

Using the latest release also provides better stability and performance.

Fix 5: Clear App Cache

Corrupted cache files can prevent NetMirror from launching correctly.

On Android:

1. Open Settings
2. Apps
3. NetMirror
4. Storage
5. Clear Cache

If problems continue, choose Clear Data as well.

Then sign back into the app if necessary.

Fix 6: Check Required Permissions

NetMirror needs several permissions to work correctly.

Verify that it can access:

• Local network
• Nearby devices
• Wi-Fi
• Notifications
• Screen recording (if required)
• Storage (if needed)

Without these permissions, casting may fail.

Fix 7: Disable VPN

Many users forget they’re connected to a VPN.

A VPN changes network routing and may prevent your TV from appearing.

Try:

1. Disconnect VPN
2. Restart NetMirror
3. Scan again

If your TV appears afterward, the VPN was likely the cause.

Fix 8: Enable Screen Mirroring on Your TV

Some televisions disable casting by default.

Open your TV settings and ensure that:

• Screen Mirroring is enabled
• Wireless Display is turned on
• Chromecast is available
• AirPlay is enabled (for iPhone)

Different TV brands place these options in different menus.

Fix 9: Reinstall NetMirror

If updating doesn’t help, reinstalling often fixes hidden problems.

Steps:

1. Delete NetMirror.
2. Restart your device.
3. Install the newest version.
4. Grant all permissions again.

This removes damaged files that updates sometimes leave behind.

Fix 10: Check Whether the Service Is Temporarily Down

Occasionally, the issue isn’t your device at all.

If many users report the same problem:

• App won’t load
• Login fails
• Streaming unavailable
• Server timeout

The NetMirror service could be temporarily unavailable.

Waiting a few hours is often enough until maintenance finishes.

NetMirror Keeps Crashing

If the app opens and immediately closes, try these fixes:

• Free up storage space
• Update Android or iOS
• Close background apps
• Restart your device
• Reinstall NetMirror

Low memory is one of the most common reasons for repeated crashes.

NetMirror Can’t Find My TV

If your TV never appears in the device list, check these items:

✓ Same Wi-Fi network

✓ TV powered on

✓ TV supports wireless casting

✓ VPN disabled

✓ Router restarted

✓ Nearby Devices permission enabled

✓ TV casting enabled

Usually one of these solves the issue.

NetMirror Is Stuck on Loading

An endless loading screen usually indicates one of the following:

• Poor internet connection
• Temporary server issue
• Outdated version
• Corrupted cache
• Network timeout

Restart the app after clearing the cache.

NetMirror Has No Sound

If video works but audio doesn’t:

• Increase TV volume.
• Restart both devices.
• Disconnect Bluetooth headphones.
• Check audio output settings.
• Reconnect the casting session.

Some TVs automatically switch audio outputs during casting.

NetMirror Is Lagging

Lag or stuttering usually comes from network congestion.

Improve performance by:

• Moving closer to the router
• Using 5GHz Wi-Fi
• Closing downloads
• Disconnecting unused devices
• Reducing network traffic

A stronger wireless signal often eliminates delays.

Device Compatibility

NetMirror generally works best on:

• Android phones
• Android tablets
• iPhone
• iPad
• Android TV
• Smart TVs
• Chromecast-compatible devices
• Windows PCs (depending on version)

Older TVs without wireless display support may require an external streaming device.

Frequently Asked Questions

Why does NetMirror keep disconnecting?

The most common reasons are unstable Wi-Fi, weak signal strength, VPN interference, or power-saving settings that interrupt background connections.

Why can’t NetMirror find my Smart TV?

Make sure both devices are connected to the same Wi-Fi network, screen mirroring is enabled on the TV, and your phone has permission to access nearby devices.

Does NetMirror work without Wi-Fi?

In most cases, no. NetMirror relies on a shared local network for device discovery and screen casting.

Should I reinstall NetMirror?

Yes. If you’ve already tried restarting your devices, clearing the cache, and updating the app, reinstalling NetMirror is one of the most effective troubleshooting steps.

Final Thoughts

Most NetMirror not working problems are caused by network configuration, outdated software, missing permissions, or temporary glitches—not by permanent faults. Start with the basics: ensure your phone and TV share the same Wi-Fi network, restart both devices, update the app, and clear the cache. If the issue persists, checking permissions, disabling VPNs, or reinstalling NetMirror often resolves the problem.

By following the fixes in this guide, you can usually restore NetMirror’s functionality in just a few minutes and get back to streaming or screen mirroring without frustration.
