AX88U -IoT devices lose connection

[gil80]

Hi.
The router was purchased and used in Australia with no issues.
Switched to Marlin firmware.

I have many IoT devices, however I'm getting constant issues with 4 of them.

Two types of issues:
1. Two Smart lightbulbs won't connect.
2. Camera and Air purifier connect and then will drop connection after a day or two. That is, the devices will show offline in their mobile app despite seeing them in the router's IP address.

The above two issues only started happening when I moved overseas. I took the router with me.

All devices are Xiaomi brand.

All are using 2.4Ghz antenna.
Other Xiaomi devices (1 smart lightbulb, 1 IP camera, 2 smoke detectors) never lose connection.

I'm running latest Marlin firmware as of August 18, 2022.

Is this an issue that some of you encountered?
Any ideas how to troubleshoot?

Additional note: All devices are allocated my PiHole DNS address.

Merlin not Marlin.
Do you use Dual Band SmartConnect? If not it is recommended and use default WIFI settings.
Also, there is an Asuswrt beta for the AX88U that should work well for you. Also use your RPI for something other than Pi-Hole. There are better ways to filter adds.

Hi.

What's special about the Asuswrt beta?
Is there really a better way to block ads than PiHole?
