Hi  @Sriracha02 

Thanks for posting here: Here are some steps to troubleshoot and potentially resolve the issue:

1. Check Network Configuration

• Verify mDNS Setup: Ensure that mDNS is correctly configured to allow communication between your main network and IoT network. This is crucial for device discovery in AirPlay.
• Review ACL Settings: Double-check the Access Control List (ACL) settings on your gateway to ensure that all necessary ports for AirPlay are open and correctly configured. The main ports to consider are:
  • UDP 5353 for mDNS ( Bonjour service discovery)
  • TCP/UDP 3689 for AirPlay
  • UDP 6000-6007 for video streaming
• Check for Conflicting Rules: Sometimes, ACL rules can conflict or be misordered, which might block necessary traffic. Ensure that the rules allowing AirPlay traffic are not being overridden by other security settings.

2. Update Firmware

• Update TV Firmware: Check if there are any firmware updates available for your Hisense TV that might improve AirPlay compatibility.
• Update iPhone: Ensure your iPhone is running the latest version of iOS, as updates can sometimes fix bugs related to AirPlay.

3. Reset Network Settings on iPhone

• Sometimes, network settings on the iPhone can cause issues with AirPlay. Go to Settings > General > Reset > Reset Network Settings. This will reset all network settings, including Wi-Fi passwords, VPN, and APN settings.

4. Check Wi-Fi Signal and Bandwidth

• Signal Strength: Ensure that both your iPhone and Hisense TV have a strong Wi-Fi signal. Weak signals can cause disconnections.
• Bandwidth: High-definition video streaming requires a stable and fast internet connection. If your network is congested or slow, it might cause the AirPlay stream to drop.

5. Disable QoS or Bandwidth Limitations

• If your router has Quality of Service (QoS) settings or bandwidth limitations, try disabling them temporarily to see if that resolves the issue.

6. Use a Different Wi-Fi Network

• Try connecting both your iPhone and TV to a different Wi-Fi network to rule out issues specific to your current network.

7. Check for Interference

• Other electronic devices or Wi-Fi networks can cause interference. Try changing the Wi-Fi channel on your router to see if that improves the AirPlay connection.

8. Contact Hisense Support

• If none of the above steps work, it might be a specific issue with the Hisense TV’s implementation of AirPlay. Contact Hisense support for further assistance.

9. Consider Third-Party Solutions

• If AirPlay continues to be problematic, consider using a third-party app that supports screen mirroring, which might offer better compatibility with your TV.
