Getting Started with HC15
Confidential / Preliminary
Select the Security tab to verify or edit authentication options for PPP connections.
By default, MS Windows XP enables the
option Typical with unsecured passwords
for the commonly used but unsafe PAP
authentication method. As this is the
minimum level of security supported in all
networks the setting usually enables the
subscriber to make a connection, though at
the expense of security.
Many network operators apply more secure authentication methods for PPP connections,
such as CHAP. For access to these networks, activate the Advanced (custom setting) option
and press the Settings button. On the resulting Advanced Security Settings property page,
enable / disable the authentication protocols according to the information provisioned by your
service provider.
Note: If an attempt to connect to a HSDPA or GPRS network fails, check that the
authentication protocols are properly set.
