Hi, thanks for the feedback.

Could you please swap the location of the two satellite Deco PX50s so it could help us decide whether there is something wrong with the hardware of a specific unit?

If it is not specific to a certain PX50, the Backhaul issue follows the location, since the powerline Backhual is highly related to the powerline wiring status, I think the location of the satellite PX50 is not ideal and it is suggested to change a different power socket and move it far from the home Appliances.

Wait for your reply.

Best regards.
