Internet Keeps Disconnecting?
Random drop-outs are, by nature, easy to miss in a short test. Choose 5 minutes (30 seconds is the default) and it logs every interruption with a timestamp and duration, so an intermittent problem has time to show up.
Test duration
Short tests are useful for quick checks. Longer tests are better for finding intermittent problems.
Free, no signup. The advanced test also moves test data to measure latency under load: up to a few hundred MB on a fast connection, so switch it off on metered data.
Customize: goal, connection type

Why a longer test catches more
A 30-second test samples your connection about 60 times. If your connection drops once every few minutes, a short test can easily land in a clean window and tell you everything is fine. Five minutes gives roughly 600 samples — enough for an intermittent fault to show up at least once in most cases, though still not a guarantee.
If problems happen rarer than every five minutes, use the continuous monitor instead and leave it running with alerts on.
What counts as a disconnect here
Two or more failed probes in a row, or no response for about 1.5 seconds, is logged as a disconnect with its start time and duration. A single failed probe is logged separately as a lost request. Every one of these appears in the detected-events table on your results page.
Narrowing down the cause
Test on Ethernet too
If drops disappear on a wired connection, the issue is likely Wi-Fi, not your ISP.
Note the time of day
Drops that cluster around the same time most days often point to a router overheating, a scheduled process, or peak-hour congestion upstream.
Restart the modem/router
A surprising number of recurring drops clear up after a full power-cycle (unplug for 30 seconds).
