•
Your ISP might require a login program.
Ask your ISP whether they require 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 Basic
Settings 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 spoof 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 as described in the
online document you can access from
Preparing Your Network
in Appendix
E.
You
can
also 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 as described in the online document you can access from
Preparing Your Network
in Appendix
E.
•
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 N300 wireless modem router. You
might need to go to Internet Explorer and select
Tools > Internet Options
, click the
Connections
tab, and select
Never dial a connection
.
Troubleshooting a 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.
