... one hour later - I changed nothing - the Onion Wifi appeared. I could log in and go through the setup, but only to step 2. Then the Wifi disappeared again.

Dear all,
I,m pretty new here and did my first steps with my new Onions. Somehow I forgot to order docks for my 4 new Onions. So I tried to set it up without a dock. I followed the guide "Powering the Omega with No Dock" https://docs.onion.io/omega2-docs/hardware-prep-no-dock.html and used the same "LD1117 3.3V Regulator". I measure a 3.3V and Onions LED blinks and it seems the it should boot.
But somehow I don't see a Onion Wifi. Tried almost everything now. Different power sources, different clients to enter Onions Access Point and also tried out 4 Onions...

I'm sure that I missed something or made a simple mistake - but I cant solve this by my own. Does anyone has a hint for me?

Thanks in advance.
Chris
