@TP-Link I suspect this happens more when the satellite Deco is connected to another satellite Deco as a signal source instead of to the main deco.

@TP-Link I have a version 3.8 deco m5. I never see metions of this version... Is it considered version 3?

@moeinio Had I known of this issue I would have searched for another product. I would advise you to search for a better product.
