Other problems
Cause
The NTP server IP address or
domain name is not correct.
The route to the registered
NTP server is not specified.
The filtering function of the
product is enabled.
Depending on the provider,
name resolution is not
possible immediately after
registration/update.
The product is connected
via a network provider
connection.
A private IP address is
assigned by the provider.
Internet connection may
be made automatically by
software or a device of the
PC (if the Internet connection
is made by the auto-connect
function).
Remedy
• Check that the setting is correct
by comparing with the NTP server
information you have obtained.
• Execute the ping command to the
NTP server, to make sure that the NTP
server is running.
Check the provider setting and routing
setting.
Check whether inbound filters or policy
filters block NTP port traffic (port
number 123), and if blocked, make
modifications to the filter settings.
Retry after a while.
If the product is connected via a network
provider connection, the netvolante DNS
service is not available. Directly specify
the IP address for connection.
You cannot use the netvolante DNS
service in the environment where no
global IP address is assigned to the
product.
Troubleshoot according to the
explanation of "Communication charges
of the USB data communication terminal
are abnormal" (page 181).
Troubleshoot by referring to "If you have
forgotten the password" (page 187).
