When does this happen?

IF WiFi CSI sensing project reports no data or appears non-functional when using unsupported WiFi hardware.

How others solved it

THEN Verify that the WiFi chipset supports Channel State Information (CSI) extraction. Use an ESP32-S3 ($8) with native promiscuous mode for the easiest setup. Refer to the project's supported hardware table. If using Intel 5300 or Atheros AR9580, ensure modified firmware or ath9k patches are applied. Avoid consumer laptop WiFi dongles as they almost never support CSI.
