NWA130BE V7.40(1) Firmware Issue

Hi @Rinas ,

Thank you for joining the remote session. Here's a summary:

After downgrading to 7.30P4, we could still see high channel load, non-Wi-Fi interference, and a high noise floor, and the 5GHz SSID was still not detectable.

The symptom went away after performing a cold start. We believe this is because the environment had previously experienced RF interference causing the abnormal state — after a cold start, the radio re-establishes its state and re-selects the channel and other RF parameters, which likely allowed it to temporarily recover.

If the issue recurs, please let us know so we can look into it further.
