I bought half a dozen Onion Omegas early on with the kickstarter. I am now retired and want to run MQTT, and node -red for PWM board on them. I cannot find any literature/ updates etc on the original onion omega. Help would be much appreciated.

I found two Onion Omega 1 (from the first kickstarter) and tried to set them up. Could not get beyond the wifi setup (froze there as it said "unable to connect to 'network' please try again", even thouh it showed up on my network. I was unable to (on ssh) to get oupgrade to work (cannot connect to the server). I was on my network then with the Omega 1 clearly on it as well, but it couldnt find the server. Would love some advice as to where to go from here.
