Hey there!
I bought Omega2+ without Power Dock and try to power it with LD33v (LD1117V33) (in output i have stable 3.28v).
At first all be ok, i'm loggin to 192.168.3.1 and set my settings and install python via SSH. But after 3-5 restarts (power on-off) my Omega didn't respond to open web-interface, but it was connected to my network (i saw this connection in router) and LED light.
I'm ask my seller about this situation and I decide to return Omega for diagnostics. Next day they said me "We make factory reset, now all must be okay." and sending me back my Omega.
When I got it second time, I got new problem. I can't connect to 192.168.3.1 (or omega-XXXX.local). Try to use different browsers - it doesn't help. Connecting to Omega's network going ok, LED stop flashing.

Soooo... I asking you help me with this situation. What i need to do? Is it right to try to buy a Power Dock or Expansion Dock?
Any help is appreciated.
