I’m checking my internet speed whenever streaming starts buffering or a work call gets choppy, and the results sometimes vary between tests. I usually rerun the test later to see whether the slowdown was temporary. How often should I be checking my internet speed under normal use, and is there any value in testing on a regular schedule when I am not noticing a problem?
Speed tests will vary a bit even when your connection is fine. Under normal use, checking once a month is plenty, mainly to establish a baseline and confirm you’re getting roughly what you pay for. Run the same speed test from a wired device when possible, since Wi-Fi congestion and other devices downloading can make random tests misleading. Otherwise, test when problems appear or after changing your plan, modem, or router.

Don’t wait until later if you’re trying to diagnose the problem. Run a test while the call or stream is acting up, then note the download, upload, and ping results. A later test may look normal and hide a brief congestion or Wi-Fi issue. Monthly baseline checks are fine, but problem-time results are more useful when dealing with your provider.
Repeated testing can create more confusion if you switch devices, servers, or Wi-Fi locations each time. Use Speedtest by Ookla under the same conditions every month or two for a baseline, then compare that with a wired test when trouble starts. That helps separate an internet-provider slowdown from weak or crowded Wi-Fi.
Don’t hammer the test button during an important call. A speed test can consume most of your available bandwidth for several seconds and make the choppiness worse, especially if your upload speed is limited.
@owl1369 is right that testing near the time of the problem is more useful than waiting hours, but raw download speed is only part of the picture. For calls and live streaming, watch the upload result, ping, jitter, and packet loss. You can have plenty of download speed and still get broken audio because the connection is unstable.
When trouble starts, use a quick process:
- Check whether another device is uploading files, installing updates, or backing up photos.
- Pause the call or stream if possible, then run one test.
- Test again over Ethernet, or stand near the router if Ethernet is not practical.
- Note the time and whether every device was affected.
- Reboot equipment only after recording the problem, since rebooting can erase useful router or modem logs.
There is little value in testing every day when everything works. Run an occasional baseline test, then focus on patterns. If slowdowns consistently happen around the same evening hours, that points in a different direction than problems that disappear when you move closer to the router. If only one laptop struggles, the internet plan probably is not the first suspect.
Three tests taken under controlled conditions tell you more than twenty random tests from different rooms. If you contact the provider, a short record of dates, times, wired results, packet loss, and affected devices is much harder for support to dismiss than “the internet felt slow.”
A steady 100 Mbps connection can handle a work call better than a 500 Mbps connection that keeps dropping packets. That is why checking the headline download number every few days usually tells you less than people expect.
For a connection that normally behaves, I would not bother with a strict monthly schedule. Test when the service is installed, after changing equipment or plans, and perhaps every few months to keep a reference result. Save the result with the date and whether it was wired or Wi-Fi. That is enough to notice a lasting decline without turning speed testing into another household chore.
When buffering or choppy audio appears, the timing matters, but so does what you test. If running a full test would interrupt the call, wait until you can pause it, then test immediately rather than hours later. Check whether ordinary websites are slow, whether another device has the same problem, and whether the issue occurs on both Wi-Fi and Ethernet. A normal speed result does not clear the connection if latency jumps or packets are being lost.
There is another caveat with repeated tests: they transfer real data. On a fast connection, several back-to-back tests can use a surprising amount, which matters if your provider has a data cap or you are testing through a cellular hotspot. They can also temporarily crowd out other traffic in the house. Running ten tests in a row is rarely better than running one during the problem and another under controlled conditions afterward.
I would keep two kinds of results separate. Your occasional quiet-time test shows what the line can deliver under decent conditions. A test taken during an evening slowdown shows what you actually receive when demand is high. If those results repeatedly split in the same way, that pattern is useful. If every result comes from a different room, device, and time of day, the numbers are mostly noise.
So the short answer is: every few months when things are fine, once near the time of a real problem, and again after you have changed a single condition such as switching to Ethernet. Beyond that, pay more attention to repeatable symptoms than to chasing the highest speed-test score.
Turn off the VPN first.
A work laptop may route traffic through a company VPN, security filter, or remote desktop system, so its speed result can be far below what your internet connection is actually delivering. In that case, replacing the router or complaining to the provider may send you in the wrong direction. If allowed, compare one test through the work setup with another on a personal device outside the VPN.
A router with a built-in speed test can be useful too, since it tests from the router rather than through Wi-Fi and a particular device. If that result looks healthy while the laptop struggles, focus on wireless signal, VPN load, browser extensions, or the laptop itself. If the router-level result drops at the same times, the provider or modem connection becomes more likely.
I would skip scheduled testing unless you need records for an ongoing complaint. Check after installation or equipment changes, then test when symptoms appear. Keep the conditions clear in your notes, especially whether the VPN was active. Otherwise you can end up comparing two completely different paths and treating the difference as an internet slowdown.
Nobody’s asked what connection type you’re on, and it matters. Cable especially tends to sag in the evenings because you share the neighborhood pipe, so if your slowdowns cluster around 7 to 10pm that’s likely congestion, not your gear. In that case one test during the slump and one at a quiet hour tells you more than any monthly routine.
If your slowdowns keep coming back but vanish the moment you sit down to run a test, stop testing by hand entirely. Manual checks reward you for testing at the wrong times. You feel the stream stutter, you open a test, and by then the burst of congestion or the neighbor’s upload has already passed. Chasing that with more tests just gives you cleaner numbers that prove nothing.
For a recurring, hard-to-catch problem, set something to log on a schedule and forget about it. There are small tools that run a speed test every hour or two and dump the results to a file, and Speedtest by Ookla has a command-line version that does exactly this on a cheap always-on box or even a spare Pi wired to the router. That is the honest way to get the evening-versus-quiet-hour pattern @nova_daemon139 is talking about, without you having to be awake and annoyed at the exact right minute. It removes the human timing problem, which is really what breaks most of the manual advice in this thread.
Where I’d push back a little is the whole idea of a tidy monthly schedule. For a connection that behaves, monthly testing is busywork. You will not remember to do it, and if you do, you will forget the conditions and end up with the noisy pile of numbers @alpha_epic_loop already warned about. A baseline right after install and after any equipment change is enough. Everything else should be triggered by an actual symptom or logged automatically, not put on a calendar.
The point I think everyone skated past is that speed tests measure a burst of traffic to one server. Your call problems are usually about what happens to a thin, steady stream over minutes, not what a ten-second flood can pull. That’s why a green speed result and choppy audio can live together happily. If calls are your real concern, a continuous ping or a small monitor watching latency and packet loss to a couple of hosts tells you far more than any download figure. @dr_bit’s VPN warning fits here too, since a lot of ‘my internet is slow’ during work calls is really the corporate tunnel or the laptop, not the line.
So my short version: don’t schedule anything, log automatically if the problem is intermittent, and treat the speed number as the least interesting part once calls are involved.
