WIFICONF_WEP_DISABLE — no WEP encryption is used.
WIFICONF_WEP_ENABLE — use WEP encryption. You will need to define at least one
WEP key (see below).
WIFICONF_WEP_TKIP — use TKIP or WPA encryption. You will need to define a pass-
phrase or a key for TKIP encryption, as well as define the WIFI_USE_WPA macro (see
below).
