N300 Wireless ADSL2+ Modem Router DGN2200
Changes Not Saved
If the modem router does not save the changes you make in the modem router interface,
check the following:
•
When entering configuration settings, always click the
Apply
button before moving to
another screen or tab, or your changes are lost.
•
Click the
Refresh
or
Reload
button in the Web browser. The changes might have
occurred, but the old settings might be in the Web browser’s cache.
Incorrect Date or Time
Select
Security > Schedule
to display the current date and time. The modem router uses the
Network Time Protocol (NTP) to obtain the current time from one of several network time
servers on the Internet. Each entry in the log is stamped with the date and time of day.
Problems with the date and time function can include the following:
•
Date shown is January 1, 2000. This means the modem router has not yet successfully
reached a network time server. Check that your Internet access is configured correctly. If
you have just finished setting up the modem router, wait at least 5 minutes, and check the
date and time again.
•
Time is off by one hour. The modem router does not automatically sense daylight savings
time. In the Schedule screen, select the
Adjust for daylight savings time
check box.
