@crispyoz , I was able make the WiFi SSD of the Omage2+ show up somehow after login to the device through serial. I have run wifimanager and enabled the wifi. I am not sure this is what resolved the issue but it was one of few things I have tried.
However, I have a different issue now. I cannot connect the device to my wifi with Omega2 Setup Wizard. It would say "Unable to connect to SSD_name. Please try again" on the web and I see following in the terminal having the devices connected via serial. Is there something I am doing wrong?
