Request timed out
If the path is not functioning correctly, one of the following problems might be occurring:
•
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 that the appropriate LEDs are on for your network devices. If your
modem 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
modem 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
modem 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

page 305 display. If you do not receive replies, do the following:
•
Check to see that the IP address of your
modem router
is listed as the default router in your computer.
If the IP configuration of your computer is assigned by DHCP, this information is not visible in your
computer’s Network Control Panel. Verify that the IP address of the
modem router
is listed as the
default router.
•
Check to see that the network address of your computer (the portion of the IP address specified by
the netmask) is different from the network address of the remote device.
•
If your ISP assigned a host name to your computer, enter that host name as the account name. For
more information, see one of the following sections:

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 modem,
but some additionally restrict access to the MAC address of a single computer connected to that
