@Sans36 Have u change the adapter? Maybe the adapter is not working properly that's why Deco stuck on yellow light.

@Juhis Use parental control and block the internet for your IoT devices.

@pjs_gsy How did you test the ping? From phone or PC ?

@DF8 Hope this firmware resolve your issues.

@lapsmith I have Deco M4 (V2) which support Connection Preference for client devices aswell.

@lapsmith Hmmm i think you have to update to the beta firmware 1.7.0 because David-TP said the firmware from July 2025 does'nt support Connection Preference but the beta firmware from September 2025...
