Reference Guide for the Model RO318 Cable/DSL Security Router
— Make sure the LAN LNK/ACT LED is on. If the LNK/ACT LED is off, follow the
instructions in
— Check that the corresponding Link LEDs are on for your network interface card and
for the hub ports (if any) that are connected to your workstation and router.
• Wrong network configuration
— Verify that the Ethernet card driver software and TCP/IP software are both installed
and configured on your PC or workstation.
— Verify that the IP address for your router and your workstation are correct and that the
addresses are on the same subnet.

Testing the Path from Your PC to a Remote Device

After verifying that the LAN path works correctly, test the path from your PC to a remote device.
From the Windows run menu, type:
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 gateway. If the IP
configuration of your PC is assigned by DHCP, this information will not be visible in the
control panel network utility. Go to the Run... window and run winipcfg. The IP address
of the router should appear as the Default Gateway.
— 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 router name in the
Wizard Setup.
— Your ISP could be rejecting the Ethernet MAC addresses of all but one of your PCs. Most
broadband ISPs restrict access by only allowing traffic 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
"borrow" or "spoof" the MAC address from the authorized PC. Refer to
