DWR-921 4G LTE Router
User Manual
In some cases NTP servers addresses are provided by your ISP. In this case, you need to move the
Get NTP server addresses using DHCP switch in the NTP Settings section to the right and
click the APPLY button. Contact your ISP to clarify if this setting needs to be enabled. If the Get
NTP server addresses using DHCP switch is moved to the right, the NTP Servers section is
not displayed.
To allow connected devices to use the IP address of the router in the local subnet as a time server,
move the Run as a server for the local network switch to the right and click the APPLY
button.
When the router is powered off or rebooted, the system time is reset to the default value.
!
If you have set automatic synchronization for the system time, the internal clock of the
device will be configured after connecting to the Inter net. If you have set the system time
manually, you need to set the time and date again (see above).
