- Select any detection method and set the parameters: Ping (ICMP Echo): by sending a data packet to the remote party and requesting the party to return a data packet of the same size, this method can identify whether those two devices are connected. The diagnostic results include a brief summary of the received packets, as well as the minimum, maximum, and average round trip times of the packets. Trace Route: this method records the route from the local device to the remote device. If this test succeeds, you can view the network node and the time taken from one node to the other to check whether or not there is network congestion.
- Click Detect.
