Wifi commands don't work

[mich181189]

In the documentation, it says

# If connecting to non-wpa2enterprise networks
settings.set("wifi_wpa2ent_username", None)

however when I try that I get:

>>> settings.set("wifi_wpa2ent_username", None)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "settings.py", line 29, in set
KeyError: wifi_wpa2ent_username
>>>

For me this wasn't needed anyway.

Clarified this here slightly, but yeah, only needed if you are on a WPA2 network
