+This program is to test an AP connected to a controller.  
+    The AP name is configurable.
+    The controler 
+     with with a specific ap mode, wifi mode (2.4 Ghz or 5 Ghz), Bandwidth (20,40,80,160) and TX power. 
 The controller will configure the AP.  
 The Lanforge radios are configured for a specific client dencity, Packet type (TCP, UDP), Direction (Downstream, Upstream) and Packet-size. 
 The transmission rate will be recorded and compared against the expected rate to determine pass or fail.
