4. 14. 2. Diagnostic
Diagnostic is used to test the connectivity between the router and the host or other
network devices.
1. Visit http://tplinkwifi.net, and log in with the username and password you set for the
router.
2. Go to Advanced >
• Diagnostic Tool - Select one diagnostic tool.
• Ping - This diagnostic tool troubleshoots connectivity, reachability, and name
resolution to a given host or gateway.
• Tracerouter - This diagnostic tool tests the performance of a connection.
Note:
You can use ping/traceroute to test both numeric IP address or domain name. If pinging/tracerouting the IP address is
successful, but pinging/tracerouting the domain name is not, you might have a name resolution problem. In this case,
ensure that the domain name you are specifying can be resolved by using Domain Name System (DNS) queries.
