 N300 WiFi Router
WiFi Connections
If you are having trouble connecting wirelessly to the router, try to is\
olate the problem, which 
might be one of the following: 
•
The WiFi signal strength is weak.
Check these conditions:
- Is your router too far from your computer
 , or too close? Move your computer near the 
router, but at least 6 feet (2 meters) away, and see if the signal strength improves.
- Is your WiFi signal blocked by objects between the router and your compu\
ter?
• Y
our computer or wireless devices does not find your WiFi network.
Check the following:
-Is the WiFi LED 
 on the router lit? 
If this LED is off, it is possible that someone disabled the wireless radio or set up a 
wireless schedule. For more information about these settings, see Control the 
Wireless Radio on page  70.
- Did you disable the router’
 s SSID broadcast?
If you cleared the Enable SSID Broadcast check box in the Wireless Network 
screen, your wireless network is hidden and does not display in your wir\
eless client’
 s 
scanning list. To connect to a hidden network, you must type the network name and 
the WiFi password. For more information about the SSID broadcast, see Specify 
Basic WiFi Settings on page  63.
- Does your computer or wireless device support the security that you are \
using for 
your WiFi network (WEP

, WPA, or WPA2)? 
For information about wireless security settings, see Specify Basic WiFi Settings  on 
page   63.
Changes Not Saved
If the router does not save the changes you make through the NETGEAR gen\
ie screens, do 
the following:
•When you log in to the router  and change the settings on a screen, always click the  Apply 
button before you move to another screen or tab, or your changes are los\
t. 
• Click the  Refresh or  Reload button in the web browser
 . It is possible that the changes 
might have occurred, but the old settings are in the web browser’s cache.

Troubleshoot with the LEDs
The LEDs on the front panel of the router indicate its status.
Apply Power to the Router and Check the LEDs
To apply power to the router and check the LEDs:
1. 
Connect the power adapter cord that came with the  router and plug it in to a power 
outlet. 
The Power LED lights and turns amber within a few seconds. This indicates that the  self-test is running.
2.  After approximately 30 seconds, verify that the LEDS are lit as follows:\
• The Power LED 
 is lit solid green.
• The WiFi LED 
 is lit solid green. 
• The Internet LED 
 is lit solid green.
3.  If the LEDs do not light as expected, use the LED behavior to troublesho\
ot the problem.
All LEDs Remain Lit
When the router is turned on, the LEDs light for about 10 seconds and th\
en turn off. If all the 
LEDs stay lit, a fault exists within the router.
If all LEDs are still lit one minute after power-up, try the following:
•Unplug the router’s
  power adapter cord. Plug it in again and see if the router recovers.
• T
o return the router to its factory settings, press and hold the Reset button.

• Make sure that the power adapter cord is securely connected to your rout\
er and securely 
connected to a functioning power outlet. 
• Make sure that you are using the power adapter cord that NETGEAR supplie\
d 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 recove\
ry instructions or 
help with a hardware problem, contact technical support at  www.netgear.com/support.

ternet port and 
the modem.
• Make sure that power is turned on to the connected modem.
• Be sure that you are using the correct cable.
When you connect the router’s Internet port to a cable or DSL broadband modem, use 
the cable that was supplied with the cable or DSL broadband modem. 
 This cable can be 
a standard straight-through Ethernet cable or an Ethernet crossover cabl\
e.
WiFi LED Is Off
If the WiFi LED  stays off, check to see if someone disabled the wireless radio or set up a 
wireless schedule. For more information about these settings, see Control the Wireless 
Radio on page   70. The WiFi LED is lit when the wireless radio is turned on.
Cannot Log In to the Router
If you cannot log in to the router from a computer or wireless device on\
 your local network, 
check the following:
1. Make sure that your computer or wireless device is connected to the  router’s
  network.
- For a WiFi connection, select the network and entered its WiFi password.\
- For a wired connection, use an Ethernet cable to connect your computer t\
o an 
Ethernet LAN port on the router  (not the Internet port).
2.  Launch a web browser from a computer or wireless device that is connecte\
d to the network.
3.  In the address field of your browser
 , type www.routerlogin.net  or www.routerlogin.com.
4.  If a login prompt does not display
 , try the following: 
						

							Troubleshooting 
104 N300 WiFi Router 
•Close the browser and launch it again.
•Make sure that your browser has Java, JavaScript, or ActiveX enabled. If you are 
using Internet Explorer, click the Refresh button to be sure that the Java applet is 
loaded.
•If you are using a wired connection, check the Ethernet connection between the 
computer and the router.
5. If the login prompt displays, but you cannot log in, try the following:
•Make sure that you are using the correct login information.
The user name is admin and the default password is password. Make sure that 
Caps Lock is off when you enter this information.
•If you customized the IP address scheme that the router uses, see Troubleshoot IP 
Addresses on page 108.
The Router Cannot Access the Internet
If you can log in to your router, but it cannot access the Internet, see if the router can obtain 
an IP address from your Internet provider. Unless your Internet provider assigned you a fixed 
IP address, your router requests an IP address from the Internet service. You can see if the 
request was successful using the Router Status screen.
Note:The Setup Wizard can detect your Internet connection during 
installation, but if the router cannot get a WAN IP address, the Setup 
Wizard cannot automatically resolve this issue.
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.
To check the WAN IP address: 
1. Launch a web browser from a computer or wireless device that is connected to the 
network.
2. In the address field of the web browser, enter www.routerlogin.net or 
www.routerlogin.com.
A login screen displays.
3. Enter the router user name and password.
The user name is admin. The default password is password. The user name and 
password are case-sensitive.
The BASIC Home screen displays.

105  N300 WiFi Router
4. Click the ADVANCED tab.
The Router Status screen displays.
5. In the Internet Port pane, check that an IP address is shown for the Internet port.
If 0.0.0.0 is shown, your router did not obtain an IP address from your ISP.
For more information about the Internet Port pane, see View Internet Port Information on 
page 76.
6. If your router cannot obtain an IP address from the ISP, try to force your cable or DSL 
broadband modem to recognize your new router by restarting your network in this order: 
a.Unplug and turn off the cable or DSL broadband modem. 
b. Unplug the router.
c. Plug in the cable or DSL broadband modem and turn it on. 
d. Wait two minutes.
e. Plug in the router and wait two minutes.
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 if 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.
•If your ISP allows only one Ethernet MAC address to connect to Internet and checks for 
your computer’s MAC address, do one of the following:
-Inform your ISP that you 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.
Troubleshoot Internet Browsing
If your router can obtain an IP address but your computer is unable to load any web pages 
from the Internet, it might be for any of the following reasons:
•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. 
						

							Troubleshooting 
106 N300 WiFi Router 
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. If you use Internet Explorer as 
your browser, you might need to select Tools > Internet Options, click the Connections 
tab, and select the Never dial a connection check box. Other browsers have similar 
options.
Troubleshoot a PPPoE Internet Connection
To troubleshoot a PPPoE Internet connection:
1. Launch a web browser from a computer or wireless device that is connected to the 
network.
2. In the address field of the web browser, enter www.routerlogin.net or 
www.routerlogin.com.
A login screen displays.
3. Enter the router user name and password.
The user name is admin. The default password is password. The user name and 
password are case-sensitive.
The BASIC Home screen displays.
4. Click the ADVANCED tab.
The Router Status screen displays.
5. On the Internet Port pane, click the Connection Status button.
For more information, see Check the Internet Connection Status on page 78. If the fields 
show valid information, including valid IP addresses, your PPPoE connection is up and 
working.
If any of the fields show incomplete information or no valid IP address, you can attempt to 
reconnect by clicking the Connect button. The router continues to attempt to connect 
indefinitely.
If you cannot connect after several minutes, you might be using an incorrect service name, 
user name, or password. There might also be a provisioning problem with your ISP.
Note:Unless you connect manually, the router does not authenticate using 
PPPoE until data is transmitted to the network. 
						

							Troubleshooting 
107  N300 WiFi Router
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 troubleshoot a 
network by using the ping utility on 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 computer running Windows:
1. From the Windows toolbar, click the Start button 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 the OK button.
You 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
If the path is not working, you see this message:
Request timed out
If the path is not functioning correctly, you might have one of the following problems:
•Wrong physical connections
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 
lit 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. 
						

							Troubleshooting 
108 N300 WiFi Router 
2. In the field provided, 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 like those examples shown in Test the LAN Path to 
Your Router on page 107 are displayed.
If you do not receive replies, try the following:
•Check that your computer has the IP address of your router listed as the default gateway. 
If a DHCP server assigns the IP configuration of your computer, this information is not 
visible on 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 broadband 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 Setup screen.
•Your ISP might 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, configure your router to clone or 
spoof the MAC address from the authorized computer. 
Troubleshoot IP Addresses
By default, the router is set up to automatically assign IP addresses to network clients. The 
router’s IP address is 192.168.1.1 unless you changed it. Wired and wirelessly connected 
computers must have network IP addresses on the same network as the router. The simplest 
way to meet this requirement is to configure each computer to obtain an IP address 
automatically using DHCP. 
If you customized the IP address settings of your router and you’re having trouble with 
network connections, check the following:
•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 is 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. 
						

							Troubleshooting 
109  N300 WiFi Router
•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 111.
