Troubleshooting
If you cannot connect after several minutes, you may be using an incorrect Service Name, User
Name or Password. There also may be a provisioning problem with your ISP.
Troubleshooting Internet Browsing
If your modem can obtain an IP address but your computer is unable to load any Web pages from
the Internet:
•
Your computer may 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 will provide the addresses of one or two DNS
servers for your use. If you entered a DNS address during the modem’s configuration, reboot
your computer and verify the DNS address as described in
“Verifying TCP/IP Properties” on
page C-6
. Alternatively, you can configure your computer manually with DNS addresses, as
explained in your operating system documentation
.
•
Your computer may not have the modem configured as its TCP/IP modem.
If your computer obtains its information from the modem by DHCP, reboot the computer and
verify the modem address as described in
“Verifying TCP/IP Properties” on page C-6
.
Troubleshooting a TCP/IP Network Using the Ping Utility
Most TCP/IP terminal 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. Troubleshooting a TCP/IP
network is made very easy by using the ping utility in your computer.
Testing 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 PC running Windows 95 or later:
1.
From the Windows toolbar, click the Start button and select Run.
Note:
Unless you connect manually, the modem will not authenticate using PPPoE or
PPPoA until data is transmitted to the network.
