Collecting router's Syslog

There are several ways to collect Syslog: While Syslog Explorer offers a quick way to review and download Syslog, Saving to USB disk allows the router to keep more logs and will include more information. And for some models that don't support Syslog Explorer or USB Application, we can use Syslog Tool to collect the full Syslog.

Syslog Explorer

Go to Diagnostics >> Syslog Explorer, check Enable Web Syslog and choose a Syslog Type, and the router will start to record the logs. To save the Syslog file, please click Export. Then, a file named web_syslogxxxxxxxx will be downloaded to your computer, where xxxxxxxx is the current date.
