Problem Troubleshooting Suggestion
specified for the PC is valid. Correct the address
or configure the PC to receive this information
automatically.
• Verify that a Network Address Translation rule
has been defined on the Ethernet Modem
Router to translate the private address to your
public IP address. The assigned IP address
must be within the range specified in the NAT
rules (see Chapter 4). Or, configure the PC to
accept an address assigned by another device
(see “Quick Start Part 2 — Configuring Your
Computers”). The default configuration includes
a NAT rule for all dynamically assigned
addresses within a predefined pool (see the
instructions in Chapter 8 to view the address
pool).
My LAN PCs cannot
display web pages on
the Internet. Verify that the DNS server IP address specified on
the PCs is correct for your ISP, as discussed in the
item above. If you specified that the DNS server be
assigned dynamically from a server, then verify with
your ISP that the address configured on the Ethernet
Modem Router is correct, then You can use the ping
utility, described on page 173, to test connectivity
with your ISP’s DNS server.
Web Configuration Program
I forgot/lost my Web
Configuration user ID or
password. If you have not changed the password from the
default, try using “admin” as both the user ID and
password. Otherwise, you can reset the device to the
default configuration by pressing the Reset button on
the back panel of the device three times (using a
pointed object such as a pen tip). Then, type the
default User ID and password shown above.
WARNING: Resetting the device removes any
custom settings and returns all settings to their
default values.
I cannot access the Web
Configuration program
from my web browser. Use the ping utility, discussed in the following
section, to check whether your PC can communicate
with the Ethernet Modem Router ’s LAN IP address
(by default 192.168.1.254). If it cannot, check the
Ethernet cabling.
Verify that you are using Internet Explorer v5.0 or later,
or Netscape Navigator v6.1 or later. Support for
Javascript® must be enabled in your browser. Support
for Java® may also be required.
Verify that the PC’s IP address is defined as being on
the same subnet as the IP address assigned to the LAN
interface on the
Ethernet Modem Router .
My changes to Web
Configuration are not
being retained. Be sure to use the Commit function after any changes.
This function is described on page 46.
