Chapter 13: Diagnosis Tools
This chapter introduces the features on your Synology Router to diagnose system and connection problems.
Check Connection Status
To grasp its current status and pin down the possible causes of a down connection, you need a quick, well-
rounded checkup on the wired and Wi-Fi connections at
Network Center
>
Status
. There you can also nd the
real-time network, CPU, memory usage, and device status.
For a detailed trafc log (up to one month long) of devices and applications, please go to
Network Center
>
Trafc Control
>
Monitor
.
Check Notications
The Synology Router sends instant notications to have you informed of system/connection errors via various
media (e.g. SRM desktop, SMS, and email). You can quickly zero in on the errors and nd remedies.
To tailor-make the notication service, please go to
Network Center
>

Diagnose with Ping
Ping (Packet Internet Groper) is a utility used to diagnose throttling connections. Ping works by sending out a
request packet to a target website or IP address and calculating the time lapse for receiving a response packet
from the target.
•
Normal connection
: The response packet comes from the target instantly.
•
Slow connection
: The response packet comes from the target with signicant delay.
Delayed packet transmission may occur in the suggested scenarios below:
• The target is busy dealing with huge trafc to and from other hosts/clients
• The target website/IP address is down/not working.
• The Internet/local network connection of your Synology Router is not properly congured.
• The ISP service is down.
If the problem is identied as extraneous to your Synology Router, you may consult the ISP or other relevant
service providers for assistance.
To diagnose connection problems with Ping, please go to
Network Tools

Diagnose with Traceroute
Traceroute is a utility used to diagnose throttling connections, and works by tracing the physical route of the
packets sent from your Synology Router to the target website/IP address. The physical route will be displayed on
a Google Map, along with the time lapse spent between two adjacent route points.
With Traceroute, you can nd out where the trafc is currently throttling. If the problem lies extraneous to your
Synology Router, you may consult the ISP or other relevant service providers for assistance.
To diagnose connection problems with Traceroute, please go to
Network Tools
>
