Forget what it optically looks like. The reason I explicitly say that you 
should bend the motherboard is simple: this was a common issue. (Then 
something in the PCB assemble process was finished, to solve the contact 
issue).

So basically:
start on your pc: ping 192.168.0.9
connect the network cable to the device
hold the mainboard corners between your thumb and index finger, now 
slightly 'twist' the board. (either in one or the other direction). if you 
suddenly see it replying the reason is known.

The mysterious thing with this issue seems to be that when you do connect 
the daughterboard (having compoorts) usually it 'just works'.


I have recently applied a quick fix (because i needed a working camera) by 
applying a tiny piece of wood to the right rear corner of the camera when 
it was inside the housing, so the board remains 'working' because 
of the pressure. Obviously the proper solution is to send it back and get 
a working one, the board then goes again into the PCB oven, and basically 
reflows the connections 'under' the Axis Etrax chip.
