	This test can be left running and will not use a significant amount of bandwidth or resources on the computer. Then, when you have a connection problem, you can check if these pings are still showing the regular replies or if it shows the interruption. If there is a sudden increase in latency, for example, this is ~~often be~~ caused by ~~bufferbloat~~ which occurs when a device on the network is uploading a large amount of data. You can try turning off devices or individual apps, and observing the effect on the continuous ping, to track down the offender.

If there is a sudden increase in latency, for example, this is likely caused by buffer-bloat which occurs when a device on the network is uploading a large amount of data. You can try turning off devices or individual apps, and observing the effect on the continuous ping, to track down the offender.

	Here is an example of a continuous ping to CloudFlare (1.1) showing latency spikes going above 100 ms which was caused by performing a large upload. Latency over 100ms will cause noticeable delays in voice calls and lag in online gaming.

It is available for virtually all operating systems (Windows, MacOS, etc.), including most embedded network software.

	Ping measures the round-trip time for messages sent from the originating host to a destination computer that are echoed back to the source. The name comes from active sonar terminology that sends a pulse of sound and listens for the echo to detect objects under water. The program reports errors, packet loss, and a summary of the results, typically with the minimum, maximum, the mean round-trip times.

	The connection between your computer and router/modem can be tested by pinging the gateway. You can find the IP of your gateway in your connection info, ~~for example it could~~ be 192.168.1.1 in which case you would ping it by running <code>ping 192.168.1.1</code>. The pings to your gateway should show replies with less than ~~1 ms~~ of latency, otherwise there is a problem with the connection to your router, which could be caused by a weak WiFi signal, for example.		The connection between your computer and router/modem can be tested by pinging the gateway. You can find the IP of your gateway in your connection info or by running the <code>ipconfig</code> command. For example, this might be 192.168.1.1 in which case you would ping it by running <code>ping 192.168.1.1</code>. The pings to your gateway should show replies with less than 1ms of latency, otherwise there is a problem with the connection to your router, which could be caused by a weak WiFi signal, for example.
