Diagnostics

During normal operation, you do not need to use diagnostics.

 To use diagnostics:

Select Mana

gement > Diagnostics.

The following features are available on the Diagnostics screen.

• Pin

g 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.

• Dis

play the Routing Table. View the internal routing table. This information is used by

technical support and other staff who understand routing tables.

• Reb

oot 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.
