Choose your local time zone, click Enable and click the Apply button. After a successful connection to the Internet, the router retrieves the correct local time from the SNTP server you have specified. If you prefer to specify an SNTP server other than those in the drop-down list, simply enter its IP address as shown above. Your ISP may provide an SNTP server for you to use. Resync Period (in minutes) is the periodic interval the router waits before it resynchronizes the router's time with that of the specified SNTP server. To avoid unnecessarily increasing the load on your specified SNTP server you should keep the poll interval as high as possible ­ at the absolute minimum every few hours or even days. 43 5. 3. 3. 2 Firmware Upgrade Your router's "firmware" is the software that allows it to operate and provides all its functionality.
