Can’t Connect to Wireless Screen Mirroring? A Complete Guide to Common Issues & Solutions

Wireless screen mirroring is a handy feature, but you may occasionally run into connection troubles. Don’t worry—this article compiles common issues and their troubleshooting methods.

Issue 1: Unable to Find the Screen Mirroring Device

Cause 1: Device does not support the feature or is not activated
Solution: Confirm that your TV or screen mirroring device is powered on and in the signal-waiting interface.
Cause 2: Devices are not on the same network
Solution: Ensure your phone/computer and the screen mirroring device are connected to the same Wi-Fi network.

Cause 3: Network isolation

Solution: On corporate networks, network isolation may block device discovery. Try using the screen mirroring device’s Wi-Fi Direct function (direct connection without a router).

Issue 2: Connected Successfully but with Lag or High Latency

Cause 1: Wi-Fi signal interference

Solution: Connect the device to the 5GHz Wi-Fi band—it has less interference than the 2.4GHz band, which helps reduce lag.

Cause 2: Insufficient network bandwidth

Solution: Pause other devices that are consuming network resources (such as those downloading files or streaming videos) to free up bandwidth.

Cause 3: Device performance bottleneck

Solution: Restart both the screen mirroring device and your phone/computer to clear background processes and free up system resources.

Issue 3: Screen Mirroring Suddenly Disconnects

Cause 1: Fluctuating network connection

Solution: Check the router’s status (e.g., whether it’s overheated or disconnected from the internet) to ensure a stable network.

Cause 2: Device sleep mode

Solution: In your phone or computer settings, extend the “auto-lock” or “sleep” time to prevent the device from entering sleep mode and disconnecting the mirroring session.
