Request timed out
If the path is not functioning correctly, one of the following problems might be present:
• Wrong physical connections
For a wired connection, make sure that the numbered LAN port LED is lit for the port to which you are
connected.
Check to see that the appropriate LEDs are lit for your network devices. If your router and computer are
connected to a separate Ethernet switch, make sure that the link LEDs are lit for the switch ports that
are connected to your computer and router.
• Wrong network configuration
Verify that the Ethernet card driver software and TCP/IP software are both installed and configured on
your computer.
Verify that the IP address for your router and your computer are correct and that the addresses are on
the same subnet.
Test the Path From Your Computer to a Remote Device
To test the path from your computer to a remote device:
1. From the Windows toolbar, click the Start button and select Run.
2. In the Windows Run window, type
ping -n 10 <IP address>
where <IP address> is the IP address of a remote device such as your ISP DNS server.
If the path is functioning correctly, messages display that are similar to those shown in Test the LAN
Path to Your Router on page 208.
3. If you do not receive replies, check the following:
• Check to see that IP address of your router is listed as the default gateway for your computer. If
DHCP assigns the IP configuration of your computers, this information is not visible in your computer
Network Control Panel. Verify that the IP address of the router is listed as the default gateway.
• Check to see that the network address of your computer (the portion of the IP address specified by
the subnet mask) is different from the network address of the remote device.
• Check to see that your cable or DSL modem is connected and functioning.
• If your ISP assigned a host name to your computer, enter that host name as the account name on
the Internet Setup page.
• Your ISP might be rejecting the Ethernet MAC addresses of all but one of your computers.
Many broadband ISPs restrict access by allowing traffic only from the MAC address of your broadband
modem. Some ISPs additionally restrict access to the MAC address of a single computer connected to
that modem. If your ISP does this, configure your router to “clone” or “spoof” the MAC address from the
authorized computer.
