Hi  @HYEAN 

Thanks for posting here.

There are currently no reported issues related to this problem in the official firmware. Here are a few troubleshooting steps you can try:

1. Check QoS Settings: Ensure download bandwidth is not being limited.
2. Adjust Wi-Fi Channels: Use the Omada Controller to scan for interference and switch to a less congested channel (e.g., 36/149).
3. Test Wired Speeds: Verify if the issue persists over a wired connection to rule out upstream problems.
