![]() It's important to use multiple tools and tests to diagnose latency issues and ensure that your network is running smoothly. These scenarios using ping can help troubleshoot network latency issues and identify specific points of failure in the network infrastructure. If there is high packet loss, it could indicate issues with the network infrastructure or the remote host. The output will display the packet loss rate. Type ping -f in the command prompt or terminal. Ping Flood Test: Use the ping command with the -f flag to perform a flood test and identify the maximum packet rate before lost packets occur. If there is a high response time at a specific router, it could indicate an issue with that router or network segment. The output will display the response time and the IP address of each router the ping passes through. Type ping -T in the command prompt or terminal. Ping Traceroute: Use the ping command with the -T flag to perform a traceroute and identify the specific point where latency is occurring. If the response time is high or there are lost packets, it could indicate issues with the remote host or the network infrastructure. Type ping in the command prompt or terminal. Ping a Remote Host: Ping a remote host on the internet to check if latency issues are due to the network infrastructure or the remote host. If the response time is high or there are lost packets, it could indicate issues with the local network or router. ![]() Ping the Default Gateway: Ping the default gateway to verify that your computer can communicate with the local network. If the response time is high, it could indicate an issue with your computer's network adapter or other hardware problems. ![]() Type ping localhost in the command prompt or terminal to check if the response time is within an acceptable range. Ping the Local Host: Start by pinging the local host to ensure that your computer is functioning correctly. Here are some scenarios using ping to troubleshoot network latency (the following commands are different on mac and linux): The Ping statistics at the bottom of the output show that the minimum, maximum, and average round-trip times were 9ms, 12ms, and 10ms, respectively. The "time" value for each packet represents the round-trip time in milliseconds, or the amount of time it took for the packet to travel from the computer to the Google server and back. In this example, the Ping command sent four packets of data to the IP address associated with and received all four packets back without any loss. Minimum = 9ms, Maximum = 12ms, Average = 10ms Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),Īpproximate round trip times in milli-seconds: ![]() Here is a an example of what the results of the Ping Command might look like: Pinging with 32 bytes of data: Repeat the test several times over a period of minutes or hours with multiple sites and devices to get a more accurate picture of network latency over time. ![]() If the RTT is high (over 100 ms) or fluctuates significantly, you may have latency issues that require further investigation. If the RTT is consistently low (less than 50 ms), your network latency is likely performing well. You will see the results of each ping attempt in the Command Prompt or Terminal window, including the round-trip time (RTT) in milliseconds.Īnalyze the results of the ping test. The command will send several packets of data to the target device (in this case, the Google website) and test the time it takes for the responses to be received. Type ping followed by the IP address or hostname of the device you want to test. Open a Command Prompt or Terminal window on your computer. Here is an example of using the Ping command to test network latency: You can verify this on multiple devices and scenarios in your network This can be a quick and easy way to get a basic measurement of network latency. Ping is a simple command-line utility that sends a small packet of data to a specific IP address and tests the time it takes for the response to be received. ![]()
