Cant connect to node x60
Last year, I bought 2 TP-Link x60 Wi-Fi extenders. I placed one on the ground floor and the other on the upper floor, connected by an Ethernet cable. After around 4 months, the extender on the upper floor stopped working properly. It shows that it's connected to the system, but no device can connect to it. It doesn't perform "roaming," meaning that it doesn't matter if it's closer to the extender on the upper floor, it still connects to the one downstairs. I've tried resetting the extenders and even swapped their positions, but I can't find a solution
