DLNA Screen Mirroring Failed? Troubleshooting Steps and Common Problem Solutions
Want to easily binge-watch shows using DLNA, but your phone can’t find the TV device, or it connects but can’t play? Don’t worry, DLNA screen mirroring has certain network requirements. This article provides detailed troubleshooting steps and solutions for common problems.
Step 1: Basic Environment Check (Solves 90% of Problems)
-
Confirm Same Network: This is the most basic prerequisite. Ensure your phone and TV/receiver device are connected to the same Wi-Fi network, and that the network can access the internet normally.
-
Enable TV DLNA Function: Some TVs’ DLNA or “Multi-Screen Interaction” functions may need to be manually enabled in the settings.
Step 2: Device and Software Troubleshooting
-
Problem: The phone app cannot find the “TV” screen mirroring button or cannot find the device.
-
Solution:
-
Restart the phone app and smart TV.
-
Update the video app and TV system to the latest version.
-
Check if the TV supports the DLNA protocol (consult customer service or the manual).
-
Step 3: In-Depth Network Troubleshooting
-
Problem: Can find the device but cannot play or playback stutters.
-
Solution:
-
Disable Router AP Isolation: This feature prevents devices from discovering each other and needs to be disabled in the router’s administration interface.
-
Check Network Bandwidth: Ensure a good Wi-Fi signal. Playing 4K video requires high network bandwidth.
-
Restart Router: Clear the router’s temporary cache to resolve potential connection conflicts.

DLNA Limitations
It should be noted that DLNA is mainly used for pushing networked videos and music. If you want to play downloaded, copyrighted videos stored locally on your phone (such as certain downloaded theatrical movies), it may fail due to encryption. In this case, you need to try screen mirroring.
By systematically following the steps above, most DLNA screen mirroring problems can be easily resolved, allowing your multi-screen interaction experience to return to smoothness.
