Antenna genius suddenly powered off...Now, when I toggle the power.....it powers up..then a second later it powers down....

That sounds like a fuse kicking in.
It's usually caused by a short circuiting caused by a faulty cable (pins are connected wrongly or something like that).

I suggest disconnecting all peripherals and powering it on.
If it stays powered on then it's some peripheral - keep connecting one at a time to find which one causes the problem.

Ok...well...all that is connected is the ethernet cable....power and antennas..

Do you have another power supply to try?
