Quick Tips 

This section describes tips for troubleshooting some common problems. 
Sequence to Restart Your Network 
Be sure to restart your network in this sequence: 

1. Turn off and unplug the modem.
2. Turn off the router and computers. 
3. Plug in the modem and turn it on. Wait 2 minutes.
4. Turn on the router and wait 2 minutes.
5. Turn on the computers.

Power LED 

Check the Power LED to verify correct router operation. If the Power LED does not turn off within 2 minutes after you turn the router on, reset the router according to the instructions in Factory Settings. 

Check Ethernet Cable Connections 
Make sure that the Ethernet cables are securely plugged in: 

• The Internet LED on the router is lit if the Ethernet cable connecting the router and the modem is plugged in securely and the modem and router are turned on.
• For each powered-on computer connected to the router by an Ethernet cable, the corresponding numbered router LAN port LED is lit.

Wireless Settings 
Make sure that the wireless settings in the computer and router match exactly. 

• For a wirelessly connected computer, the wireless network name (SSID) and wireless security settings of the router and wireless computer need to match exactly.
• If you set up an access list in the Advanced Wireless Settings screen, you have to add each wireless computer’s MAC address to the router’s access list.

Network Settings 
Make sure that the network settings of the computer are correct: 

• Wired and wirelessly connected computers need to have network (IP) addresses on the same network as the router. The simplest way to do this is to configure each computer to obtain an IP address automatically using DHCP.
• Some cable modem service providers require you to use the MAC address of the computer initially registered on the account. You can view the MAC address in the Attached Devices screen.

Troubleshoot with the LEDs 

After you turn on power to the router, the following sequence of events should occur: 

1. When power is first applied, verify that the Power LED  lights. 
2. After 2 minutes, verify the following:
   • The Power LED lights solid green.
   • The Internet LED lights.
   • The 2.4 GHz and 5 GHz LEDs light.

The LEDs on the front panel of the router can be used for troubleshooting. 

Power LED Is Off or Blinking 

• Make sure that the power cord is securely connected to your router and that the power adapter is securely connected to a functioning power outlet.
• Check that you are using the 12V DC, 5A power adapter that NETGEAR supplied for this product.
• If the Power LED blinks slowly and continuously, the router firmware is corrupted. This can happen if a firmware upgrade is interrupted, or if the router detects a problem with the firmware. If the error persists, you have a hardware problem. For recovery instructions, or help with a hardware problem, contact technical support at https://www.netgear.com/support/.

LEDs Never Turn Off 
When the router is turned on, the LEDs light for about 10 seconds and then turn off. If all the LEDs stay on, there is a fault within the router. 
If all LEDs are still lit 1 minute after power-up: 

• Cycle the power to see if the router recovers.
• Press and hold the Restore Factory Settings button to return the router to its factory settings as explained in Factory Settings.

If the error persists, you might have a hardware problem and should contact technical support. 

Internet LED Is Off 
If the Internet LED does not light, check the following: 

• Make sure that the Ethernet cable connections are secure at the router and at the modem or computer.
• Make sure that power is turned on to the connected modem or computer.
• Be sure that you are using the correct cable.
• When connecting the router’s Internet port to a cable or DSL modem, use the cable that was supplied with the cable or DSL modem. This cable could be a standard straight-through Ethernet cable or an Ethernet crossover cable.

2.4 GHz and 5 GHz LEDs Are Off 
If these LEDs stay off, check to see if the Wi-Fi On/Off button on the router has been pressed. This button turns the wireless radios in the router on and off. The 2.4 GHz and 5 GHz LEDs are lit when the wireless radios are turned on. 

Cannot Log In to the Router 

If you are unable to log in to the router from a computer on your local network, check the following: 

• If you are using an Ethernet-connected computer, check the Ethernet connection between the computer and the router as described in the previous section.
• Make sure that your computer’s IP address is on the same subnet as the router. If you are using the recommended addressing scheme, your computer’s address should be in the range of 192.168.1.2 to 192.168.1.254.
• If your computer’s IP address is shown as 169.254.x.x, recent versions of Windows and Mac OS generate and assign an IP address if the computer cannot reach a DHCP server. These autogenerated addresses are in the range of 169.254.x.x. If your IP address is in this range, check the connection from the computer to the router, and reboot your computer.
• If your router’s IP address was changed and you do not know the current IP address, clear the router’s configuration to factory defaults. This sets the router’s IP address to 192.168.1.1. This procedure is explained in Factory Settings on page  123.
• Make sure that your browser has Java, JavaScript, or ActiveX enabled. If you are using Internet Explorer, click Refresh to be sure that the Java applet is loaded.
• Try quitting the browser and launching it again.
• Make sure that you are using the correct login information. The factory default login name is admin and the password is password. Make sure that Caps Lock is off when you enter this information.
• If you are attempting to set up your NETGEAR router as a replacement for an ADSL gateway in your network, the router cannot perform many gateway services. For example, the router cannot convert ADSL or cable data into Ethernet networking information. NETGEAR does not support such a configuration.

Cannot Access the Internet 

If you can access WNDR4300 router but not the Internet, check to see if the router can obtain an IP address from your Internet service provider (ISP). Unless your ISP provides a fixed IP address, your router requests an IP address from the ISP. You can determine whether the request was successful using the Router Status screen. 

To check the WAN IP address

1. Start your browser, and select an external site such as https://www.netgear.com/.
2. Access the router interface at https://www.routerlogin.net/.
3. Select Administration > Router Status.
4. Check that an IP address is shown for the Internet port. If 0.0.0.0 is shown, your router has not obtained an IP address from your ISP.

If your router cannot obtain an IP address from the ISP, you might need to force your cable or DSL modem to recognize your new router by restarting your network, as described in Sequence to Restart Your Network.
If your router is still unable to obtain an IP address from the ISP, the problem might be one of the following: 

• Your Internet service provider (ISP) might require a login program. Ask your ISP whether it requires PPP over Ethernet (PPPoE) or some other type of login.
• If your ISP requires a login, the login name and password might be set incorrectly.
• Your ISP might check for your computer’s host name. Assign the computer host name of your ISP account as the account name in the Internet Setup screen.
• Your ISP allows only one Ethernet MAC address to connect to Internet and might check for your computer’s MAC address. In this case, do one of the following:
  • Inform your ISP that you have bought a new network device, and ask them to use the router’s MAC address.
  • Configure your router to clone your computer’s MAC address.

If your router can obtain an IP address, but your computer is unable to load any web pages from the Internet: 

• Your computer might not recognize any DNS server addresses.
  • A DNS server is a host on the Internet that translates Internet names (such as www addresses) to numeric IP addresses. Typically, your ISP provides the addresses of one or two DNS servers for your use. If you entered a DNS address during the router’s configuration, reboot your computer, and verify the DNS address. You can configure your computer manually with DNS addresses, as explained in your operating system documentation.
• Your computer might not have the router configured as its TCP/IP gateway.
  • If your computer obtains its information from the router by DHCP, reboot the computer, and verify the gateway address.
• You might be running login software that is no longer needed.
  • If your ISP provided a program to log you in to the Internet (such as WinPoET), you no longer need to run that software after installing your router. You might need to go to Internet Explorer and select Tools > Internet Options, click the Connections tab, and select Never dial a connection.

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 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 yet successfully reached a network time server. Check that your Internet access is configured correctly. If you have just 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 2.4 GHz and 5 GHz LEDs on the front of the router. They should be lit. If they are not, you can press the Wireless button on the front of the router to turn the routers wireless radios back on.
  • If you disabled the router’s SSID broadcast, then your wireless network is hidden and does not show up in your wireless client's scanning list. (By default, SSID broadcast is enabled.)
  • If your wireless device finds the network but you cannot join the network, check to make sure your wireless device is compatible with the network that you selected (2.4 GHz or 5 GHz).
• Does your wireless device support the security that you are using for your wireless network (WPA or WPA2)?
  • If you want to check 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 Wireless Settings Screen Fields on page 29).

Note: Be sure to configure both sections (for 2.4 GHz b/g/n and 5 GHz a/n) on the Wireless Settings screen and to click Apply if you make changes. 

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 (1.8 meters) away, and see if the signal strength improves.
• Is your wireless signal blocked by objects between the router and your 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 configuration settings shown in the following table. 

Maximum Wireless signal rate derived from IEEE Standard 802.11 specifications. Actual throughput can vary. Network conditions and environmental factors, including volume of network traffic, building materials and construction, and network overhead, lower actual data throughput rate.
