Hi, Thank you very much for the feedback.

I think "-65dbm" is a quite good wireless signal level. Distance as well as the wireless interference over the same WiFi band will affect the final wireless signal strength.

You can read more details here: https://www.metageek.com/training/resources/understanding-rssi/

On the different applications, they might use different RSSI levels and there are 3 levels(Strong/Medium/Fair) of Signal Strengths on the Deco APP:

Strong：>-50dbm

Medium：-50dbm~-70dbm

Fair: <-70dbm

Best regards.
