Hi Chen,
I’m having same issues with iPad (running iOS 17.5.1, which is same as my iPhone)
On iPad,
1) I’ve removed ASIAIR app
2) reboot iPad
3) installed ASIAIR (2.1.5, latest as of July 21, 2024)
4) privacy&security:location services: ASIAIR:always
5) local network : ASIAIR : on
6) Wi-Fi network: private ip address : off
My ASIAIR is wired to a small wifi extender: gl-ar300m, and that extender is connected to my home internet wifi wifi.
My ASIAIR is not in station mode.
My iPhone has no problem connecting to the ASIAIR over my home network. I can even turn off cellular on my iPhone, and just have on my wifi home network and it connects to the ASIAIR.
My phone settings are in the attached screenshot.
Best
Robert
