Sorry guys! Just saw SDuquet and his findings just sum up the solution to my problems!

Guess maybe just this title will help someone troubleshoot this more promptly than me !

I've received the Omega today and found out that it doesn't find my home's wifi AP. I wanted to upgrade its firmware through the serial connection but when I run 'screen' the screen just goes blank and I get no output whatsoever.

Also I noticed that maybe the Omega doesn't stand too firm on the Expansion Dock because sometimes the RGB led turns on and cycles through different colors as the pins in the Omega make contact or not.

Any tips?
