How to test your Wi-Fi speed properly
A Wi-Fi speed test is easy to run and even easier to misread. Five minutes of method turns a random number into an actual diagnosis.
What a Wi-Fi test actually measures
A speed test measures the whole chain at once: your device's radio, the air between you and the router, the router itself, and only then your internet line. The number you get is the weakest link of that chain — which over Wi-Fi is very often the radio part, not your provider.
That is why one number in isolation proves little. Run as a comparison — near the router versus at your desk, Wi-Fi versus cable — the same test suddenly tells you exactly where the speed goes missing.
Set up a fair test
Give the test a quiet line: pause cloud backups, game downloads and 4K streams on every device, and turn off your VPN (it caps speed and adds latency wherever it is on).
Then check which band you are on. Standing next to the router, a phone on 5 GHz or 6 GHz should see hundreds of Mbps; parked on 2.4 GHz it may cap at 20–60 Mbps no matter how good your plan is. If your network broadcasts one combined name, your device chooses — and it sometimes chooses badly.
One more silent ceiling: the device itself. Old laptops and budget phones carry radios that top out at 100–200 Mbps. If two devices disagree about your Wi-Fi, believe the newer one.
Run three tests, not one
First, a baseline: wired if you can, or one meter from the router on 5 GHz. This is close to what your ISP actually delivers, and it is the number to compare against your plan.
Second, the spot that matters — your desk, the sofa, the home office. Third, the worst corner you actually use. Run each test two or three times and compare the middle result; Wi-Fi varies moment to moment, and a single run can mislead in either direction.
If evening speeds are the complaint, repeat the baseline at 9 pm. A line that is fast at 7 am and slow at night points at congestion, not at your router.
Read the numbers
Baseline good, far spot bad: coverage problem. That is placement, band choice or building materials — see the Wi-Fi guide for the fixes, and consider wired access points or mesh before any "booster" gadget.
Everything low, even next to the router: the bottleneck is the router, the plan, or the line itself. Re-test wired; if the cable number is also far below your plan, that conversation belongs with your ISP.
And watch latency and jitter, not just Mbps: for calls and gaming, a stable 25 ms beats a jumpy 8 ms. Our test also measures latency under load — the bufferbloat number that explains why calls stutter while someone streams.
Five minutes, full picture
Baseline, real spot, worst spot — three numbers, and your Wi-Fi has nowhere to hide. Run the first one now: the test is free, takes half a minute, and your results never leave your device.
