For the life of me I am trying to figure out how to get an OptiPlex 7010 USFF desktop connected via wireless using the onboard miniPCIe card. So far nobody at Dell has been able to tell me what the parts are that I need to do it. I know I need the miniPCIe card and the antenna. - The part that I cannot figure out is the adapter hat connects the miniPCIe on the board to the external antenna.

There is an opening on the back of the 7010 USFF where the external antenna can plug in, but it does me no good when it doesn't have anything to plug into. Anybody know what I need and what the actual part numbers are?
