How long is the warranty period for this machine? I use one for pfSense and am getting errors on one of the Ethernet ports -- hardware errors, and they are increasing in number, as time goes by.
One year warranty.
Could you provide the order number or invoice number? The sales will contact you by email.

what kind of wifi card do i have to get for this!!

My unit will not boot unless there is a VGA cable attached. I want to use this as a headless server without the VGA cable. Is there a BIOS setting I'm missing that controls this?
No, all Qotom Mini PC must connect a monitor, HDMI or VGA

We bought 8 Q190G4 to replace existing firewalls and edge servers with pfSense services.

It is a very nice product.

I've only a question. In case of black out the box has to be powered with the press of the power button.

Can it be possible to have an automatic power on ?

Yes, Q190G4 support automatic power on. You can set it in BIOS:
Advanced -- ACPI Settings -- Restore AC Power Loss (Choose Power On) -- F10 Save & Exit

I'm sorry that it cann't run on battery supply.
The package contains power supply (12V 5A adapter and plug).
