WIFI_WEP_KEY0–3
These are the secret keys that are programmed into each device on a WLAN to use WEP
(Wired Equivalent Privacy). Each of these keys must be entered correctly in order for
WEP to work.
Each of the four WEP keys is an array of either 5 or 13 binary bytes, not an ASCII string.
Set
to these as 64-bit or 128-bit keys. The 24 “extra” bits that are included in the marketing
description serve as a cryptographic initialization vector.
WIFI_AUTH
The authentication option is used to configure different types of authentication that the
Wi-Fi device supports. There are three types of authentication that are supported—open-
system authentication (
