@hunterkcabe If I understand well, you have 3 Deco, a main Deco somewhere, then 2 satellite Deco in the same room.
One of the satellite Deco (AX3000) is connected by an Ethernet cable to the main Deco, while the other satellite (AX4300) is connected by wifi to the main Deco or to the other satellite Deco.
Is that correct?
And you observe that your devices are all connecting to the AX3000, correct?
Is it not optimal for those devices to connect to the AX3000?
What is the purpose of having two satellites in the same room? What benefit do you expect from that?
