I have several units of the Roteador Wi-Fi 6 Gigabit Dual Band AX1500 EasyMesh TR-069 EX141 (versions v1.0 and v1.8) presenting the same issue: the 2.4 GHz Wi-Fi signal disappears, while the 5 GHz Wi-Fi signal continues to function normally.

I performed bench tests using all firmware versions available for the EX141 model on the official TP-Link website. However, the issue persists — the 2.4 GHz signal keeps dropping, while the 5 GHz Wi-Fi signal remains stable and operational.

I have also tried the following solutions without success:

Separating the networks (disabling Band Steering):
Accessed the web interface → Wireless menu → configured different SSIDs (e.g., “MyNetwork_2.4” and “MyNetwork_5”) to prevent automatic device steering.

Changing channel and channel width:
Manually set the 2.4 GHz channel to 1, 6, or 11 and fixed the channel width to 20 MHz (avoiding “Auto” or 40 MHz for better stability).

Firmware update:
Installed the latest firmware versions as well as tested previous versions available on the official website.

Reboot and factory reset:
Performed a simple reboot and a full factory reset (holding the reset button for 10 seconds), followed by complete reconfiguration.

Even after all these procedures, the problem continues to occur.

Has anyone experienced this issue with this model and found a definitive solution?
