Hi,
I have couple of onion 2S+ modules.

I have played with the "wireless" and "network" configurations and for some combinations, the wireless section won't work. I don;t remember exactly what are those, but a working config is provided below. Please compare with your Omega.

@ab09 We need to know what firmware version you are using.

Make sure you have you updated to the latest firmware version.
Perform a factory reset to you can be sure it is nothing you have done to mess up the configuration.
When booting do you see the Warp Core splash screen?

Some people have had issues connecting to WiFi if they have the device set to US frequencies. In /etc/config/wireless look for this :

config wifi-device 'radio0'
option type 'ralink'
option variant 'mt7628'
option country 'US'

Remove it and reboot.

If that doesn't fix the issue, try fixing the channel instead of option channel 'auto' set it to a valid channel for your region. Channel 11 is usually good but your situation may differ so you can try anything in the range 1 - 11 for 2.4Ghz
