@TP-Link thank you will try these.

@TP-Link Hi, How do perform steps 3 (SSID) to 4? For step 5, tried connecting the problematic satellite Deco via ethernet cable to the main deco and it worked. But how do I connect/add it wireless?...

Hi Guys, Just want to ask if anyone can help me with the issue I'm facing with my M5. So I have 3 nodes and for 3 weeks they are working perfectly fine until one of the nodes got disconnected...
