14. The Preamble (see Figure 22) allows you to adjust the preamble mode for a 2.4GHz/11Mb
network to Long, Short, or Auto. The default preamble mode is Long.
15. There are three different security Authentication Methods that may be selected as shown in
Figure 23. Open System or Shared Key (the default selection) allows the device to accept
connection requests from any wireless device in its operating range, while Shared Key
allows only devices with the same 64-bit WEP (Wired Equivalent Privacy) or 128-bit WEP
encryption key access to the device, and WPA-PSK (Wi-Fi Protected Access-Pre-Shared
Key) allows only devices with the same TKIP (Temporal Key Integrity Protocol) encryption
key access to the device.
16. The Encryption field can be None, 64-bit WEP, 128-bit WEP or TKIP, depending on which
Authentication Method was chosen. If Shared Key was chosen, 64-bit and 128-bit WEP
encryption keys may be manually assigned (by entering digits in the four WEP Key fields) or
automatically generated (by entering 8 to 64 letters, numbers or symbols in the Passphrase
field). In this case, the four WEP Keys will be generated when you click on the Apply button.
NOTE: You must specify which of the generated WEP Keys you want to be the default
WEP Encryption Key in the Default Key field.
17. If WPA-PSK was chosen as the Authentication Method, you must enter a Passphrase in
that field, and set the WPA Re-key Timer value (1-2,147,483,647 seconds). This will
determine the time interval before the WPA group key is changed. A shorter time interval will
make for a more secure wireless network.
