							Troubleshooting 
71  N150 and N300 Wireless Routers
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.
•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.
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 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.
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. Type http://www.routerlogin.net or http://www.routerlogin.com. 
						

							Troubleshooting 
72 N150 and N300 Wireless Routers 
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 View the Internet Connection Status on page 57. 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.
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 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
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
For a wired connection, make sure that the numbered Ethernet port LED is lit 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 
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.
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 72 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 Settings 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.
•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 76.
