Status
9.1 Diagnostics
The Diagnostics menu provides feedback on the connection status of the router and the DSL link.
The individual tests are listed below. If
a test displays a fail status, click Test at the bottom of this screen to make sure the fail status is consistent. If the test continues to fail, click
Help and follow the troubleshooting procedures provided onscreen.
Test
Description
Ethernet Connection
Pass: Indicates that the Ethernet interface from your computer is connected to the LAN port of your
router.
Fail: Indicates that the router does not detect the Ethernet interface on your computer.
Wireless Connection
Pass: Indicates that the Wireless interface from your computer is connected to the wireless network.
Down: Indicates that the router does not detect the wireless network.
ADSL
Synchronization
Pass: Indicates that the router has detected an ADSL signal from the telephone company.
Fail: Indicates that the router does not detect a signal from the telephone company’s DSL network.
Additional tests are added here based upon connection type.

Description
Log
Indicates whether the system is currently recording events.
The user can enable or disable event
logging.
By default, it is disabled.
To enable it, tick Enable and then Apply button.
Log level
Allows you to configure the event level and filter out unwanted events below this level.
The events
ranging from the highest critical level “Emergency” down to this configured level will be recorded to
the log buffer on the device SDRAM.
When the log buffer is full, the newer event will wrap up to the
top of the log buffer and overwrite the old event.
By default, the log level is “Debugging,” which is
the lowest critical level. The following log levels are
• Emergency = system is unusable
• Alert = action must be taken immediately
• Critical = critical conditions
• Error = Error conditions
• Warning = normal but significant condition
• Notice= normal but insignificant condition
• Informational= provides information for reference
• Debugging = debug-level messages
Emergency is the most serious event level, whereas Debugging is the least important. For instance,
if the log level is set to Debugging, all the events from the lowest Debugging level to the most critical
level Emergency level will be recorded.
If the log level is set to Error, only Error and the level above
will be logged.
Display Level
Allows the user to select the logged events and displays on the View System Log screen for events
of this level and above to the highest Emergency level.
Mode
Allows you to specify whether events should be stored in the local memory, or be sent to a remote
syslog server or both simultaneously.
If remote mode is selected, view system log will not be able to display events saved in the remote
syslog server.
When either Remote mode or Both mode is configured, the WEB UI will prompt the user to enter the
Server IP address and Server UDP port.
3: Click View System Log.
The results are displayed as follows.
