N150 Wireless ADSL2+ Modem Router DGN1000Bv3
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 five minutes, and check the date
and time again.
• T
ime is off by one hour. The modem router has an automatic daylight saving time setting.
To change the modem router setting for daylight saving time:
1. Select Security > Schedule.
2. Select the Automatically adjust for daylight savings time check box.
3. Click the Apply button.
Your changes are saved.
TCP/IP Network Not Responding
Most TCP/IP terminal devices and routers have a ping utility for sending an echo request
packet to the designated device. The device responds with an echo reply to tell whether a
TCP/IP network is responding to requests.
Test the LAN Path to Your Modem Router
You can ping the modem router from your computer to verify that the LAN path to your
modem router is set up correctly.
To ping the modem router from a Windows computer:
1. From the Windows taskbar, click the
Start button, and select Run.
2. In the field provided, type ping followed by the IP address of the modem router, as in this
example:
ping 192.168.0.1
3. Click the OK button.
A message such as the following one displays:
Pinging <IP address> with 32 bytes of data
If the path is working, you see this message:
Reply from < IP address >: bytes=32 time=NN ms TTL=xxx
