NETGEAR N300 Wireless Router with External Antennas WNR1500 User Manual 
-     
Verify that the Ethernet card driver software and TCP/IP software are both 
installed and configured on your computer.
-     
Verify that the IP address for your router and your computer are correct and that 
the addresses are on the same subnet.
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 then 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 your ISP’s DNS server.
If the path is functioning correctly, replies like those shown in the previous section are 
displayed. If you do not receive replies:
•     
Check that your computer has the IP address of your router listed as the default gateway. 
If the IP configuration of your computer is assigned by DHCP, this information is not be 
visible in your computer’s Network Control Panel. Verify that the IP address of the router 
is listed as the default gateway.
•     
Check to see that the network address of your computer (the portion of the IP address 
specified by the subnet mask) 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 Basic Settings screen.
•     
Your ISP could be rejecting the Ethernet MAC addresses of all but one of your computers. 
Many broadband ISPs restrict access by allowing traffic only from the MAC address of 
your broadband modem, but some ISPs additionally restrict access to the MAC address 
of a single computer connected to that modem. If this is the case, you must configure 
your router to “clone” or “spoof” the MAC address from the authorized computer. 
Problems with Date and Time
Select Content Filtering > Email to display a screen that shows the current date and time of 
day. The WNR1500 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, 2000. 
Cause: The router has not yet successfully reached a network time server. Check that 
your Internet access settings are correct. If you have just completed configuring the 
router, wait at least 5 minutes, and check the date and time again.
