Wi-Fi card for Mac Pro 2014 Mid

Your system choice needs to be checked, there is no 2014 after Apple produced the 2013 the Mac Pro Trash Can, Apple didn’t make a new Mac Pro until 2019 which went back to the Cheese Grater design.

Assuming you have an older 2009~12 system your system offers a special port for a AirPort adapter which gets you Bluetooth and WiFI services, but they are older versions of the Bluetooth and WiFI standard (802.11n) Mac Pro Airport card (09/10/12).

Today I recommend using an Ethernet to WiFI bridge so via the systems Ethernet port so you can span the distance or just hard wire the connection. You then get better throughput as well!
