Solutions
Verify in Windows Explorer that file extensions are
displayed and the ini file is not XXX.ini.ini by mistake.
Also verify that the extension ini is in lowercase letters.
Verify that the TFTP server settings are as follows:
Timeout = 2 sec,
# of retransmission = 10
An old ini file was probably loaded. Check which ini file
was loaded by using the Syslog server. The Gateway
displays contents of ini file before it began.
Check the ini file syntax
Check that only your BootP server contains the TP-
1610's MAC address.
