User’s Manual
These macros specify the WEP keys to use for WEP encryption. These keys can be
either 40-bit or 104-bit (i.e., 5 bytes or 13 bytes). They must be defined as a comma-
separated list of byte values.
Note that you do not necessarily need to define all four WEP keys. You may typically
just define one key, but make sure it matches the key used on all other devices, and set
IFC_WIFI_WEP_KEYNUM
If both
for a particular key, the hex version will be used.
The following macro must also be used to compile WPA functionality into the Wi-Fi
driver. This is necessary to enable TKIP encryption.
passphrase on your access point. It may also point to a variable.
Define an ASCII passphrase here, from 1 to 63 characters long. An example is shown
below.
If possible, you should use
WPA_PSK_PASSPHRASE
digits that matches the 256-bit (64-byte) hexadecimal key used by your access point.
Specify a 64 hexadecimal digit (256 bits) key here. This key will be used and will over-
ride any passphrase set with the

Using a passphrase is rather slow. It takes a Rabbit 5000 more than 20 seconds to gen-
erate the actual 256-bit key from the passphrase. If you use a passphrase and
WIFI_VERBOSE_PASSPHRASE
corresponding to that passphrase and SSID.

key authentication.
