settings. From the main menu, under Maintenance, select Backup Settings.
The following sections describe the available options.
Backing Up and Restoring the Configuration

containing your router’s configuration settings.
Note:
If the router is rebooted, the table data is lost until the router rediscovers the
devices.

To save your settings, click
Back Up
. Your browser extracts the configuration file from the router
and prompts you for a location on your computer to store the file. You can give the file a
meaningful name at this time, such as
comcast.cfg.
To restore your settings from a saved configuration file, enter the full path to the file on your
computer, or click
Browse
to browse to the file. When you have located it, click
Restore
to send
the file to the router. The router then reboots automatically.
Erasing the Configuration
Under some circumstances (for example, if you move the router to a different network or if you
have forgotten the password), you might want to erase the configuration and restore the factory
default settings. After an erase, the router’s user name is
admin
, the password is
password
, the
LAN IP address is
192.168.1.1
(or
www.routerlogin.net
), and its DHCP server is enabled.
To erase the configuration, click the
Erase
button in the Backup Settings screen.
To restore the factory default configuration settings when you do not know the login password
or IP address, you must use the restore factory settings button on the bottom of the router (see
“Restoring the Default Configuration and Password” on page 8-14
).
Tip:
Before saving your configuration file, change the administrator password to the
default,
password
. Then change it again after you have saved the configuration file.
If you forget the password, you will need to reset the configuration to factory
defaults.
Warning:
Do not interrupt the reboot process.

Note:
Be sure to change the router’s default configuration password to a very secure
password. The ideal password should contain no dictionary words from any
language, and should be a mixture of letters (both uppercase and lowercase),
numbers, and symbols. Your password can be up to 30 characters.
Note:
For enhanced security, restrict access to as few external IP addresses as
practical.

To allow access from a single IP address on the Internet, select
Only This Computer
.
Enter the IP address that will be allowed access.
3.
Specify the port number for accessing the management interface.
Normal Web browser access uses the standard HTTP service port 80. For greater security,
enter a custom port number for the remote management Web interface. Choose a number
between 1024 and 65535, but do not use the number of any common service port. The default
is 8080, which is a common alternate for HTTP.
4.
Click
Apply
to have your changes take effect.
Note:
When accessing your router from the Internet, type your router’s WAN IP address
into your browser’s address or location field, followed by a colon (:) and the
custom port number. For example, if your external address is 134.177.0.123 and
you use port number 8080, then enter
in your browser.
