I recently bought a Mac Pro. Unfortunately it came without an Airport card. I purchased a Belkin Wireless G+ MIMO USB Adapter. Is there a way to make my Mac Pro connect to WiFi with it? When I connect the adapter, nothing happens.
Just open the System Preferences -> Network pane and once there select the wireless device (if it recognized by the Mac). The installed Airport card is a standard wireless card so I am trying to figure out why you bought a third party redundant wireless card.
