I am experiencing issues with video playback on my Android devices when connected to a TP-Link Deco XE75 mesh router.

Problem:

When using video streaming apps like TVer or Amazon Prime Video on my Android devices (Google Pixel 7 Pro, Amazon Fire TV Stick 4K, XGIMI Horizon), the videos fail to start and time out. This issue is specific to Android devices connected to the Deco XE75, as I have tested with other routers ( including the Archer C9) and iOS devices without encountering the same problem.

　(TVer is a free Japanese streaming service that lets you watch TV shows you missed on terrestrial television.)

Troubleshooting:

I have tried various troubleshooting steps, including:

• Restarting the router and devices
• Clearing app cache
• Resetting network settings
• Replacing the main Deco unit
• Adjusting Deco settings (default, priority, mesh off)

Environment:

• Router: TP-Link Deco XE75 (Firmware version 1.2.9, Rev 2.0JP)
• Network: Fiber optic (nuro)

I have contacted TP-Link support in Japan, but they were unable to provide a solution.

I would appreciate any assistance in resolving this issue.
