You restart the router, or switch from cable to fiber, or finally move the access point out of the closet. You run a speed test. The number looks better — or does it? Now you are digging through your camera roll for the screenshot from last week, trying to remember if that was Wi-Fi or wired, morning or evening, before or after. By the time you find it, you have talked yourself out of trusting either number.
Our Internet Speed Test now holds up to three results at once, side by side, so that comparison happens on the page instead of in your head.
How it works
- Run a full test as usual.
- Click Compare this result.
- Change the thing you actually want to test — switch networks, move rooms, plug in an Ethernet cable, restart the router, whatever it is.
- Press GO again. The new run joins the same panel automatically — no extra click needed.
- Repeat once more if you want a third.
Each column gets an editable label (it guesses "Wi-Fi" or "Mobile" from your connection, but you can rename it to whatever you're actually testing — "Old router", "Bedroom", "Before firmware update"), and the fastest download, fastest upload and lowest ping in the panel are highlighted, so the winner is obvious without reading every number in every column.
A few ways to actually use it
The tool doesn't know what you're testing for, so here are the comparisons that come up most:
- Wi-Fi vs. wired. Run one test on Wi-Fi, plug into the router with a cable, run a second. If wired is dramatically faster, the connection itself is fine and the slowdown is happening over the air — see our fiber vs cable vs DSL post for what to do about it.
- Before and after a change. New router, firmware update, moved access point, added a mesh node — compare before and after in the same session instead of trusting a screenshot from a different day.
- Room by room. If you're renting the place out, our guest Wi-Fi checklist already recommends testing at the sofa, the desk and the far bedroom — now those three results land in one panel instead of three screenshots.
- Shopping for a plan. Testing at a neighbor's or a friend's place on a different provider? Three connection types, one comparison.
- Peak hours vs. quiet hours. Cable connections in particular slow down when the whole neighborhood is home in the evening. Run a test at 6 p.m. and another at midnight to see how much of your "slow internet" is actually rush hour.
Reading the panel honestly
A highlighted "best" number is the highest download or upload, or the lowest ping, among the columns you have — it is not a claim that the difference is meaningful. Back-to-back tests naturally vary by a few percent even when nothing changed, because of momentary network conditions at that exact second. If two results are within a few Mbps of each other, that's noise, not a verdict. A change worth trusting is usually large, and it holds up if you re-test. The speed test page itself says it plainly: a single run is a snapshot, not a verdict — comparing a few snapshots gets you closer to the truth than trusting just one.
Frequently asked questions
Does comparing use extra data?
Yes. Each entry in the comparison is a full, real speed test, so it uses the same data a normal test would. Comparing three results means running the test three times.
Are my comparison results saved or shared anywhere?
No. The comparison lives only in your browser tab for that visit. Nothing is sent to our server or anyone else, and it disappears when you close the tab (a page reload keeps it, closing the tab does not).
Why does my second test show a different number even though I changed nothing?
Some variance between back-to-back runs is normal — a few percent either way from network conditions at that exact moment, not a real change. Treat a small difference as noise; a change worth acting on is usually large and consistent if you re-test.
Can I compare more than three results?
Not at once. Three is the limit so the panel stays readable. Remove one of the three (the × on its column) to free a slot for another test.
