Wireless screen mirroring technology may encounter various connection problems during use. Mastering the correct troubleshooting methods can quickly restore functionality and ensure the smooth progress of teaching and meetings.
- Unable to discover devices
- Incomplete device list
- Frequent device disconnections
- Picture freezing and lag
- Frequent connection interruptions
- Audio-video desynchronization
- Network connectivity test: Verify that all devices are connected to the same network and check for network congestion or failures.
- Device status confirmation: Ensure the receiving device (projector, TV, etc.) is powered on, in screen mirroring mode, and not in sleep state.
- Distance and obstacle check: Confirm that the transmitting device (phone, computer) is within the effective wireless range and that there are no thick walls or metal obstacles blocking the signal.
- Network frequency band adjustment: Switch the wireless screen mirroring device to the 5G Hz band (less prone to interference) if it was previously using 2.4G Hz.
- Interference source identification: Move away from devices that may cause interference, such as microwaves, Bluetooth speakers, or other high-power electronic equipment.
- Device compatibility verification: Check if the transmitting device supports the protocol of the receiving device (e.g., Miracast for Android, AirPlay for Apple) and update device drivers or system versions if necessary.
Establish a daily maintenance mechanism:
- Regular device inspections: Check the working status of wireless screen mirroring devices, antennas, and network routers weekly.
- System update management: Timely update the firmware of screen mirroring devices and the operating systems of transmitting devices to fix known bugs.
- Backup plan preparation: Prepare wired connection alternatives (e.g., HDMI cables) or spare wireless screen mirroring adapters for emergency use during critical teaching or meetings.
