Hi.. I need some help. I have AX88U setup as AiMesh Router. RT-AC1900P as node.

Everything seems to work fine until this weekend. When I update the RT-AC1900P with newest firmware. My internet Devices connect to the AiMesh setup are unable to get connect. THe newest firmware is: 3.0.0.4.385.20585 . I tried to reconnect. But they all seem to unable to connect.

To trouble shoot, i turn off RT-AC1900P. Devices connected.... So that firmware is making my 2.4g band unable to connect. Note: Its not all devices on 2.4. Only few specific one. Like Phillips Air purifier. Chamberlain Home Bridge.

After i down grade back to previous version: FW_RT_AC1900P_300438520490, my devices power cycle are able to automatic get connected.

I have update to the latest firmware. I did some experiment with 2.4 Wifi Setting. I already disable AX/Wifi 6 Related configuration. I notice that there was a recommendation when IoT is having issue. For 2.4G, I also disable Target Wake Time. This seems to work. My IoT devices now can connect to the AiMesh Node.;)
