ping -n 10 IP address

where

IP address

is the IP address of a remote device such as your ISP’s DNS server.

If the path is functioning correctly, replies as in the previous section are displayed. If you do

not receive replies:

•

Check that your PC has the IP address of your router listed as the default wireless

modem router. If the IP configuration of your PC is assigned by DHCP, this information

will not be visible in your PC’s Network Control Panel. Verify that the IP address of the

router is listed as the default wireless modem router as described in the online document

that you can access from

Preparing Your Network

in Appendix C.

•

Check to see that the network address of your PC (the portion of the IP address specified

by the netmask) is different from the network address of the remote device.

•

Check that your cable or DSL modem is connected and functioning.

•

If your ISP assigned a host name to your PC, enter that host name as the account name

in the Basic Settings screen.

•

Your ISP could be rejecting the Ethernet MAC addresses of all but one of your PCs. Many

broadband ISPs restrict access by allowing traffic only from the MAC address of your

broadband modem, but some ISPs additionally restrict access to the MAC address of a

single PC connected to that modem. If this is the case, you must configure your router to

“clone” or “spoof” the MAC address from the authorized PC.

Restoring the Default Configuration and Password

This section explains how to restore the factory default configuration settings, changing the

router’s administration password to

password

and the IP address to

192.168.0.1

. You can

erase the current configuration and restore factory defaults in two ways:

•

Use the Erase function (see

Backing Up, Restoring, and Erasing Your Settings

on

page 53).

•

Press the Restore Factory Settings button on the bottom of the router.

Using the Restore Factory Settings Button to Reset the Router

To restore the factory default configuration settings when you do not know the administration

password or IP address, use the Restore Factory Settings button on the bottom of the router:

1.

Press and hold the Restore button until the Power LED turns red (about 6 seconds).

2.

Release the Restore button. The LED blinks red three times and then turns green when the

router has reset to the factory default state. Wait for the router to reboot.

Problems with Date and Time

In the main menu, under Security, select Schedule to display the current date and time of

day. The wireless modem router uses the Network Time Protocol (NTP) to obtain the current
