 ==== Commands Useful for Access Points ====
-For the purposes of clarity, I use **wlan0** as an example name in these. I do this to avoid putting square brackets and braces around command variables. Style choice.
+For the purposes of clarity, these are examples, not prototypes.
-.Get stats on all the wireless clients connected to your access point.
+Get basic info, channel, mode, etc..
