Diagnostics
During normal operation, you do not need to use diagnostics.
To use diagnostics:
Select Management > Diagnostics.
The following features are available on the Diagnostics screen.
•
Ping an IP address
. Use this to send a ping packet request to the specified IP address.
Ping can be used to test a connection. If the request times out (no reply is received), this
usually means that the destination is unreachable. However, some network devices can
be configured not to respond to a ping.
•
Perform a DNS Lookup
. A Domain Name Server (DNS) converts Internet names to IP
addresses. If you need the IP address of a server on the Internet, you can do a DNS
lookup to find the IP address.
•
Display the Routing Table
. View the internal routing table. This information is used by
technical support and other staff who understand routing tables.
•
Reboot the Router
. Perform a remote reboot (restart). You can do this if the modem
router seems to have become unstable or is not operating normally.
Note:
Rebooting stops any network connections to the modem router or
through the modem router. Connections to the Internet are
automatically reestablished when possible.
