Netgear RAX20-100CNS power adapter

Hi, I have a Netgear RAX20-100CNS router and I'm looking for the exact dimensions of the barrel plug so I can connect it to a custom 12V power supply and what else if needed to know to make that work. I am an electronics repairman but want to be sure of the physical dimensions. Also if there are other specifics so I can order a correct barrel plug. 

 

Thank you.

    The standard plug size for netgears 12v plugs should be 5.5mm outside diameter / 2.1mm inside

        I have seen reports here of one or two devices with adapters that aren't standard when it comes to tip size.

         

        Have you looked into generic adapters with sets of tips?

        Some of the transformers sold on line even lay claim to be compatible with Netgear devices.

         

        Netgear's devices seem to be pretty standard. I have various old power bricks lying around from old USB drives and the like that work just fine. The key requirement is the right polarity and voltage and enough amps.
