I just setup a completely new RPI3+ HassOS instance. Only SSH & Web terminal add-on was installed.
After boot up, I can connect perfectly via LAN cable.
After setup WIFI connection and static IP address and reboot, I can connect via LAN calbe and also via WIFI.
I used this guide: Guide: Connecting Pi with Home Assistant OS to wifi (or other networking changes)
If I disconnect LAN cable, it is stop communication on WIFI as well. Not possible to connect via WIFI. Even if I set up DNS and GATEWAY (my router is using 192.168.1.1).
USB stick and my-network file setup method is not working at all for me. Does nothing.
Any idea or suggestion?
