i guess theres no solution , right?
I think there are some.
Please read the official Onion Omega2 Documentation - at least the First Time Setup carefully. There are some different methods - for example with the web based Console or with ssh or with the Serial Terminal.
Try to do one of them step by step more carefully.
Try to use the 192.168.3.1 IP address instead of omega-ABCD.local when you want to connect to Omega2's AP.
Please try to use the default onioneer password - instead of oniooner !!!.
