@chromenumero If you have active cable TV then you should have a MoCa POE filter to prevent signal leaking to the outside, it should be placed at the highest splitter point of the network hierachy...

@FongMan Nice, what is the switch that you use now? I'm having some issues with a tplink switch.

@BillsDunk Mind if I ask how did it go? I have a tplink 2.5gpbs and it still sometimes dropped connection for 1 satellite unit. Let me know if that works for you.

@skondolf Just fiy your x55 has a new update v1.3.1 here, double check your hardware version as well : https://www.tp-link.com/us/support/download/deco-x55/v1/#Firmware

@Oxley What is your Netgear model? Also your X55 seems to have new update firmware v1.3.1 here for manually upgrade: https://www.tp-link.com/us/support/download/deco-x55/v1/#Firmware

Your topology seems to be correct when all nodes in AP mode. Why don’t you try this topology in case 2 here to see if that changes anything: https://community.tp-link.com/en/home/forum/topic/271538...
