Section 11 - Troubleshooting
1. From the PC’s Windows toolbar, Click Start and in the search box at the bottom, type cmd and
press Enter.
2. Type ping -n 10 <IP_address> where -n 10 species a maximum of 10 tries and <IP address> is
the IP address of a remote device such as your ISP’s DNS server. Example: ping -n 10 10.1.1.1.
3. Press Enter and then observe the display (see the previous procedure).
4. If the path is not working, do the following:
• Check that the PC has the IP address of your rewall listed as the default gateway. (If the
IP conguration of your PC is assigned by DHCP, this information is not visible in your PC’s
Network Control Panel.)
• Verify that the network (subnet) address of your PC is dierent from the network address
of the remote device.
• Verify that the cable or DSL modem is connected and functioning.
• Ask your ISP if it assigned a hostname to your PC. If yes, select Network > Internet >
WAN1 Settings or WAN2 settings, select DHCP as the Connection Type, and enter the
Host Name.
• Ask your ISP if it rejects the Ethernet MAC addresses of all but one of your PCs.
Many broadband ISPs restrict access by allowing trac from the MAC address of only your
broadband modem; but some ISPs additionally restrict access to the MAC address of just a single
PC connected to that modem. If this is the case, congure your rewall to clone or spoof the MAC
address from the authorized PC.
