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 one of the following reasons:
•
The traffic meter is enabled, and the limit was reached.
By configuring the traffic meter not to block Internet access when the traffic limit is reached, you can resume
Internet access. If your ISP sets a usage limit, they might charge you for the overage.
•
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, restart your computer.
Alternatively, you can configure your computer manually with a DNS address, as explained in the documentation
for your computer.
•
The router might not be configured as the default gateway on your computer.
Reboot the computer and verify that the router address (www.routerlogin.net) is listed by your computer as the
default 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 the
Never dial a connection
. Other browsers provide similar options.
Troubleshoot PPPoE
If you are using PPPoE, try troubleshooting your Internet connection.
To troubleshoot a PPPoE connection:
1.
Launch a web browser from a computer or WiFi device that is connected to the network.
2.
Enter
.
A login window opens.
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 page displays.
4.
Click the
ADVANCED
tab.
The ADVANCED Home page displays.
5.
In the Internet Port pane, click the
Connection Status
button.
The Connection Status window opens.
6.
Check the Connection Status window to see if your PPPoE connection is up and working.

If the router is not connected, click the
Connect
button.
The router continues to attempt to connect indefinitely.
7.
If you cannot connect after several minutes, the router might be set up with an incorrect service name, user
name, or password, or your ISP might be experiencing a provisioning problem.
Unless you connect manually, the router does not authenticate using PPPoE until data is transmitted to the network.
Changes Not Saved
If the router does not save the changes that you make in the router interface, do the following:
•
When entering configuration settings, always click the
Apply
button before moving to another page or tab, or
your changes are lost.
•
Click the
Refresh
or
Reload
button in the web browser. It is possible that the changes occurred, but the old
settings might be in the web browser’s cache.
WiFi Connectivity
If you are experiencing trouble connecting to a router WiFi network, try to isolate the problem:
•
Does the computer or WiFi-capable device that you are using find your WiFi network?
If not, check the 2.4 GHz, 5 GHz-1, or 5 GHz-2 LED on the top of the router. If these LEDs are off, you can press
the
WIFI
button on the front of the router to turn the router WiFi radios back on.
If you disabled the router’s SSID broadcast, then your WiFi network is hidden and does not display in the list of
networks that your computer or WiFi device finds. (By default, SSID broadcast is enabled.)
•
Does your WiFi-capable device support the security that you are using for your WiFi network (WPA or WPA2)?
•
If you want to view the WiFi 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
BASIC > Wireless
.
Be sure to click the
Apply
button if you change settings.
Note
•
If you are trying to connect to the 5 GHz 1 or 5 GHz 2 band, does your computer or WiFi-capable device support
this standard?
•
Did your computer or WiFi device automatically connect to a different WiFi network in your area, such as a WiFi
hotspot?
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 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 Windows computer:
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 <IP address > 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, one of the following problems might be occuring:
•
Wrong physical connections
For a wired connection, make sure that the numbered LAN 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
To 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
<IP address>
where
<IP address>
is the IP address of a remote device such as your ISP DNS server.

If the path is functioning correctly, messages display that are similar to those shown in
Test the LAN Path to
Your Router
on page 188.
3.
If you do not receive replies, check the following:
•
Check that IP address of your router is listed as the default gateway for your computer. If DHCP assigns
the IP configuration of your computers, this information is not visible in your computer 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 on the
Internet Setup page.
•
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.
Some ISPs additionally restrict access to the MAC address of a single computer connected to that modem. If
your ISP does this, configure your router to “clone” or “spoof” the MAC address from the authorized computer.
