Test the Path from Your Computer to a Remote Device

After verifying that the LAN path works correctly, test the path from your computer to a remote
device.
1. From the Windows toolbar, click the Start button, and select Run.
2. In the Windows Run window, type:
ping -n 10 <IP address>
where <IP address> is the IP address of a remote device such as the DNS server of your
ISP.
If the path is functioning correctly, replies as in the previous section display. If you do not
receive replies:
•Check that your computer has the IP address of your router listed as the default wireless
access point. If the IP configuration of your computer is assigned by DHCP, this
information is not visible in your computer’s Network Control Panel. Verify that the IP
address of the router is listed as the default wireless access point.
•Check to see that the network address of your computer (the portion of the IP address
specified by the netmask) is different from the network address of the remote device.
•Check that your cable or DSL modem is connected and functioning.
•If your ISP assigned a host name to your computer, enter that host name as the account
name in the basis General system settings screen (see Configure Basic General System
Settings and Time Settings on page 23).
Problems with Date and Time
The Time Settings screen that is accessible through the Configuration > System > Basic >
Time menu choices displays the current date and time of day. The wireless access point uses
the Network Time Protocol (NTP) to obtain the current time from a network time server on the
Internet that you specify in the Time Settings screen (see Configure Basic General System
Settings and Time Settings on page 23). Each entry on the Logs screen is stamped with the
date and time of day. Problems with the date and time function can include the following:
•Date and time shown is Fri Dec 31 00:00:00 1999 or a similar incorrect date and time.
Cause: The wireless access point has not yet successfully reached the network time
server. Check that your Internet access settings are configured correctly. If you have just
completed configuring the wireless access point, wait at least 5 minutes and check the
date and time again.
•The day is correct or one day ahead or behind, and the hours are ahead or behind.
Cause: You have selected an incorrect time zone for your area. Specify the correct time
zone in the basic General system settings screen (see Configure Basic General System
Settings and Time Settings on page 23).
