TP-LINK TAPO C425 Camera Wifi Signal Weak

Firmware Update v1.2.25

Research confirms a known software logic defect in firmware version 1.2.23 that prevents the camera from roaming to the strongest available mesh node. This update recalibrates the RSSI threshold logic and roaming aggressiveness, ensuring the radio selects the node with the lowest path loss. This resolves the symptom of the camera connecting to a distant, weak signal source instead of a nearby one.

If firmware optimization does not resolve the issue, the root cause is environmental attenuation (physics) where the 2.4GHz signal is absorbed by structural materials like concrete or masonry. Adding a dedicated mesh node closer to the camera's location reduces the free-space path loss (FSPL) and improves the signal-to-noise ratio (SNR) by shortening the physical distance between the transmitter and receiver.
