4-20 Diagnostics (Ping & Tracert)
The Ping / Trace Route Diagnostics can be independently selected by clicking on either
"Ping" or "Tracert" on the left hand menu. These features are handy tools for diagnosing
network faults and ISP service faults.
Ping - Operates in a similar way to most Ping utilities, It will send a ping via the ICMP
protocol and receive a response from the target if it is configured to respond. You can
choose if the ping originates from the LAN (Private) side of the router or from the WAN
(Public) side of the router.
Note: Just because a computer does not respond to a ping doesn't mean it is not
functional or on the same IP address. Computers and routers can be
configured to NOT respond to pings and yet they can still transfer TCP / IP
data. Most Windows default installations will respond to a Ping.
Hint: For testing WAN (internet) connectivity it is handy to perform a DOS ping to a
website from a computer that has confirmed internet access via another router
or modem to obtain a IP number for your router test see the screen shot
