101  N600 Wireless Dual Band Router WNDR3400v3
Changes Not Saved
If the router does not save the changes you make in the router interface, check the following:
•When entering configuration settings, always click the Apply button before moving to 
another screen or tab, or your changes are lost. 
•Click the Refresh or Reload button in the web browser. The changes might have 
occurred, but the old settings might be in the web browser’s cache.
Incorrect Date or Time
Select Advanced > Security > Schedule to display the current date and time. The 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. This means the router has not successfully reached a 
network time server. Check that your Internet access is configured correctly. If you have 
finished setting up the router, wait at least 5 minutes, and check the date and time again.
•Time is off by one hour. The router does not automatically sense daylight savings time. In 
the Schedule screen, select the Automatically adjust for daylight savings time check 
box.
Wireless Connectivity
If you are having trouble connecting wirelessly to the router, try to isolate the problem. 
•Does the wireless device or computer that you are using find your wireless network?
If not, check the Wireless LEDs on the front of the router. They should be lit. If they are 
not, you can press the WiFi On/Off button on the side of the router to turn the router’s 
wireless radio back on. You need to press and hold the WiFi On/Off button until the LED 
status changes.
If you disabled the router’s SSID broadcast, your wireless network is hidden and does not 
show up in your wireless client’s scanning list. (By default, SSID broadcast is enabled.)
•Does your wireless device support the security that you are using for your wireless 
network (WPA or WPA2)?
•If you want to view the wireless settings for the router, use an Ethernet cable to connect a 
computer to a LAN port on the router. Then log in to the router and select Setup > 
Wireless Settings see (
Basic Wireless Settings on page 29). 
Note:Be sure to click Apply if you make changes. 
						

							Troubleshooting 
102 N600 Wireless Dual Band Router WNDR3400v3 
Wireless Signal Strength
If your wireless device finds your network, but the signal strength is weak, check these 
conditions:
•Is your router too far from your computer, or too close? Place your computer near the 
router, but at least 6 feet away, and see whether the signal strength improves.
•Is your wireless signal blocked by objects between the router and your computer?
Restore the Factory Settings and Password
To restore the factory settings, erasing the current configuration, and changing the router’s 
administration password back to password, you can:
•Use the Erase function of the router (see Erase on page 73).
•Use the Restore Factory Settings button on the back of the router. See Factory Settings 
on page 106. If you restore the factory settings and the router fails to restart, or the green 
Power/Test LED continues to blink, the unit might be defective. If the error persists, you 
might have a hardware problem and should contact technical support at 
http://www.netgear.com/support.
Troubleshoot Your Network Using the Ping Utility
Most network devices and routers contain a ping utility that sends an echo request packet to 
the designated device. The device then responds with an echo reply. You can easily 
troubleshoot a network by using the ping utility in your computer or workstation. 
Test the LAN Path to Your Router
You can ping the router from your computer to verify that the LAN path to your router is set up 
correctly.
To ping the router from a running Windows computer:
1. From the Windows toolbar, click Start, and select Run.
2. In the field provided, type ping followed by the IP address of the router, as in this example:
ping www.routerlogin.net
3. Click OK.
You should see a message like this one:
Pinging  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 
						

							Troubleshooting 
103  N600 Wireless Dual Band Router WNDR3400v3
If the path is not working, you see this message:
Request timed out
If the path is not functioning correctly, you could have one of the following problems:
•Wrong physical connections
For a wired connection, make sure that the numbered LAN port LED is on for the port to 
which you are connected.
Check that the appropriate LEDs are on for your network devices. If your router and 
computer are connected to a separate Ethernet switch, make sure that the link LEDs are 
on for the switch ports that are connected to your computer and router.
•Wrong network configuration
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 select Run.
2. In the Windows Run window, type:
ping -n 10 
where  is the IP address of a remote device such as your ISP DNS server.
If the path is functioning correctly, replies as 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 
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 Internet 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 so, configure your router to “clone” or “spoof” 
the MAC address from the authorized computer.

Factory Settings
You can return the router to its factory settings. Use the end of a paper clip or a similar object 
to press and hold the Restore Factory Settings button on the back of the router for at least 
5 seconds. The router resets and returns to the factory settings.
 Your device returns to the 
factory configuration settings shown in the following table.
