Diagnostic
34.1 Diagnostic Overview
The Diagnostic screen displays information to help you identify Internet connection problems with the
Zyxel Device.
34.1.1 What You Can Do in this Chapter
• The Diagnostic screen lets you select different methods to test an Internet connection (Section 34.2
on page 265).
34.2 Diagnostic
Use this screen to ping, traceroute, nslookup, or speed test for troubleshooting. Ping and traceroute are
used to test whether a particular host is reachable. After entering an IP address and clicking one of the
buttons to start a test, the results will be shown in the screen. Use nslookup to find the IP address for a host
name and vice versa. Use speed test to perform an upload and download throughput test for
applications such as file transfer, web browsing and email. Use TR-471 test to perform an Internet
connection quality test through a TR-471 test server for applications such as live streaming, online games
and VoIP.
Note: Not all Zyxel Devices support speed test.
