Access the network without logging into the captive portal on Android? I want to access the local network on a hotspot on my Android devie without logging in, but if i connect to it, i get the "Sign in to network" notification and the sign in site, but all my other traffic go through LTE.

Also other apps see like that I am not connected to any wifi network.

How should i force Android to use the wifi network as a "normal" wifi network (without logging in), and do not use LTE?

Make sure you have enabled root access for ADB in developer options
Connect you phone to your computer via usb or open a terminal emulator on your device (skip step 3)
Type adb shell to open a shell (Assuming you have adb installed)
Type su to gain superuser permissions
Tyoe settings put global captive_portal_detection_enabled 0 to prevent the Wi-Fi from disconnecting if there is no internet connection
