Stable connections are essential during the use of wireless screen mirroring. Mastering optimization techniques is crucial to ensuring the normal operation of
smart classrooms.
- Difficulty in searching for devices
- Frequent connection interruptions
- Authentication failure issues
- Picture freezing and latency
- Resolution adaptation problems
- Abnormal color display
- Use the 5GHz frequency band: Reduces interference compared to 2.4GHz and provides higher transmission rates.
- Reasonable AP deployment: Install access points (APs) in locations with uniform coverage, avoiding obstructions.
- Optimize network bandwidth: Allocate dedicated bandwidth for screen mirroring and limit non-essential network usage.
- Update drivers: Keep wireless network card drivers and firmware of receiving devices (projectors, screens) up to date.
- Optimize system settings: Adjust power management (disable wireless sleep mode) and firewall configurations to allow mirroring protocols.
- Eliminate signal interference: Keep devices away from sources of interference such as microwaves, Bluetooth devices, and other wireless transmitters.
- Regularly check device status: Inspect wireless modules, antennas, and network connections for abnormalities.
- Keep systems updated: Install operating system updates and patches to fix known connectivity bugs.
- Establish contingency plans: Prepare backup wired connections (e.g., HDMI cables) and spare devices for critical teaching scenarios.
