WLAN Profile Security Settings
Description
Passphrase
The passphrase consists of up to 63 characters.
Note: Lantronix recommends using a passphrase of 20
characters or more for maximum security. Spaces and
punctuation characters are permitted.
Note: The passphrase input is not the same as ASCII input (as
used on some products.) ASCII is translated directly into
hexadecimal bytes according to the ASCII table, while a possibly
larger passphrase is hashed into a key and provides better
security through a larger range of key values.

WLAN Profile WEP Settings
WEP security is available in both Infrastructure and AdHoc modes. WEP is a simple and
efficient security mode encrypting the data via the RC4 algorithm. However, WEP has
become more vulnerable due to advances in hacking technology. State of the art equipment
can find WEP keys in five minutes. For stronger security, please use WPA, or better, WPA2
with AES (CCMP).
WLAN Profile WEP Settings
Description
Authentication
Selects the authentication method to be used.
 Shared = encryption keys of both parties are compared as
a form of authentication. If mismatched, no connection is
established.
 Open = a connection is established without first checking
for matching encryption keys. However, mismatched keys
will result in garbled data and thus a lack of connectivity at
the IP level.
Key Size
Key size in bits. Select 40 for WEP40 and WEP64, select
104 for WEP104 and WEP128.
TX Key Index
Selects one of four indexes listing keys for transmitting data.
Reception is allowed with all four keys.
Note: For operability with some products that generate four
identical keys from a passphrase, this index must be one.
Keys 1-4
Enter one or more encryption keys in hexadecimal format.
Enter 10 hexadecimal digits (0-9, a-f) for WEP40 and 26 for
WEP104. The configured keys are not shown for security
reasons.
