Hello again,
The factory reset did seem to fix the connectivity issues. However, my setup for wifi was No Smart Connect / Hidden / WPA 2-3. It seems that as soon as I set the wifi to hidden, or WPA 2/3, the windows clients at my house can't connect anymore. Those settings were working in firmware 1.04. For now I'll stick to No Smart Connect / Visible / WPA 2. I have the feeling that my older setup (Invisible / WPA 2-3) immediately broke connectivity when firmware 1.10 got auto-installed.
Could somebody test No Smart Connect / Hidden / WPA 2-3 (instead of 2 only) too?
Thanks!
