+<li><strong>WiFi Scan</strong> displays a list of other 802.11 signals that the

+Access Points (AP), neighbor nodes (connected ad-hoc stations), and other mesh networks 
+(foriegn ad-hoc networks). The AREDN mesh is created on top of an 802.11 'ad-hoc' network.  
+Consequently when multiple ad-hoc networks are visiable to each other (different SSID or 
+channel), the 'network' is displayed and not individual nodes (stations).  There is also an 
+automatic scan mode. It is not recommend to run a wifi scan continously because this will degrade mesh 
+performance. A wifi scan transmits queries on all channels to discover other devices.<br><br></li>
