LEAP is a security protocol that provides authentication and encryption for wireless networks. 
Authentication is provided through the use of user names and passwords. There are multiple options 
for caching of these credentials available to the administrator of the device through the registry.

There are multiple password caching options used for LEAP. The methods are:

•

Save the password in the registry.

•

Save the password until a warm boot (soft reset), but not saved in the registry. This method 
also has a timeout available.

•

Never save the password, requiring a dialog box on every power-up (suspend/resume).

The default is set to cache the password until a warm boot, with no timeout. If a different password 
caching option is desired, the Spectrum24DS.reg registry file in the Platform folder must be re-
configured.

All password caching options are configured in the file Spectrum24DS.reg, located in the Platform 
folder. The file must be edited on a PC and copied back onto the device after editing is complete. The 
section of this file which needs editing reads “[HKEY_LOCAL_MACHINE\Comm\NETWLAN1\Parms].”

To cache the password, edit the registry file using a text editor with the following changes:

1.

Change the LCachePwd value from 1 to 0:

LCachePwd = dword:0

2.

Uncomment the UNAME and UPwd values (deleting the semicolons at the beginning of each 
line):

UNAME = yLEAPUserName

UPwd = myLEAPPassword

3.

Change myLEAPUserName and myLEAPPassword to the correct username and password. 
Note that the user name and password should be in quotes. If a domain name is required, 
this can be entered in the user name as: domain\username.
