Test the Path from Your Computer to a Remote Device

After you verify that the LAN path works correctly, test the path from your PC to a remote 
device. In the Windows Run screen, type:

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 described in 

on page 151 display. 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 is 
not visible in your PC’s Network Control Panel. Verify that the IP address of the router is 
listed as the default wireless modem router.

Check 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 ADSL 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 
modem, but some additionally restrict access to the MAC address of a single PC 
connected to that modem. In this case, configure your router to clone or spoof the MAC 
address from the authorized PC. 

Cannot Log In

If you cannot log in to the wireless modem router from a computer on your local network, 
check the following:

The router is plugged in and it is on.

You are using the correct login information. The login name is admin, and the password 

is password. Make sure that Caps Lock is off when you enter this information.

If you cannot connect wirelessly, try an Ethernet connection and view the router wireless 

settings and set up your wireless computer with corresponding wireless settings.

If you are using an Ethernet-connected computer, check the Ethernet connection 

between the computer and the router. The LAN LED for the port you are using on the 
router should light up to show your connection.

Your computer’s IP address is on the same subnet as the router. If you are using the 

recommended addressing scheme, your computer’s address should be in the range 
192.168.0.2 to 192.168.0.254. 

If the computer IP address is 169.254.x.x, recent versions of Windows and Mac OS 

generate and assign an IP address when the computer cannot reach a DHCP server. The
