The following sections describe the available options.

Backing Up and Restoring the Configuration

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.

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.

Only This Computer

.

Enter the IP address that will be allowed access.

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.
