High Volts From Modem

Question

So. we had Cox services a few years ago and are switching back. Received the new modem by UPS that we tried to hook up and cannot. For some reason you get shocked when you touch the modem. Had an electrician out along with our power company and both say there is nothing wrong with my house and that it is on Cox. The weird part about this is that there is no voltage in the coax but when you connect it to the modem you get 33 volts on a voltage reader.&nbsp;Something is not right here....Waiting on the tech to come out.&nbsp;

Yea, defiantly need a technician. Some questions when the technician gets there:
Does the voltage go away when you unplug the coaxial from the modem(gateway)?
What about when you unplug the power and leave the coaxial in?
Does swapping to a new gateway make a difference?

Will keep these to ask. The voltage is on the modem even without the coax connected.

Unplug it until the technician comes just in case. Maybe a bad power supply? Can't tell from the pictures if it has a internal or external power supply.
I am just glad you had a electrician out already because the first thing that came to mind is a hot ground. However, that would show as current on the coaxial.

Do you have it plugged in to a grounded outlet or a grounded power strip?

Plug is grounded, checked by electrician, and it's plugged into a surge protector.&nbsp;
