When the Vigor router has an unexpected reboot or crash, we usually advise customers provide the console logs for our support team to troubleshoot the issue.

Since firmware version 3.8.4, Vigor Routers have new telnet command:

“sys con2tel enable

This command provides an easy way to collect console logs.

This article demonstrates how to use telnet to collect the console logs. Use the steps below to capture the console logs.

1.   Open the Windows Command Prompt.

  • Type “telnet” and then press Enter.


2 .  Type “set logfile xxxx.txt” to create the file that the logs will be saved into. The file path is the same as the telnet path used in step 1. (In this example, the file will be saved to C:\Users\User)


3.   Telnet to Vigor Router by typing “open Router’s IP”.

For example, if the router IP is enter the command:



4. Enter the login credentials.


5. Type “sys con2tel enable”. Then press “Ctrl+s” to start debug mode.

Debug logs will appear when there are events that match to R&D’s debug code.


6. Click l (lowercase L) will show the current memory usage status. (Same as CLI command “sys q”)


7. Keep collecting the logs until the issue occurs. Then send the log file to support.
