How do I test the external antenna port on the AirPort Extreme Base Station?
1) You should have an antenna Transceiver that is made for connecting specifically to that port (usually that means the QuickerTek product has the AE product extension; i.e. 27XVR-AE). 2) The antenna or adaptor cable is connected into the external antenna port. 3) The power supply to the Base Station is disconnected for 20 seconds. 4) Then the power is reconnected. 5) This process makes sure the AirPort Base Station recognizes the external antenna port. Now, to make sure that the external antenna port is on and working. 1) Access AirPort Admin Utility. 2) Click on the Base Station in the window. 3) Enter your password when prompted, in menu bar click on “View” then “Summary”. 4) Check the line that displays Antenna external or internal. 5) If “External” then it is working. If you have everything connected correctly and it still shows “internal”, try it one more time, then give us a call.
