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
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, 2003. This means the modem router has not yet 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 has an automatic daylight savings time
setting.
To change the modem router setting for daylight savings time:
1.
Select ADVANCED > Security > Schedule.
2.
Select the Automatically adjust for daylight savings time check box.
3.
Click Apply.
Your change is saved.
