You pay for 200 Mbps. The speed test says 40. Or the test says 200 and pages still crawl. This is one of the most common complaints in home broadband, and the reason is almost always the same: the speed on your bill describes the line coming into your home, not the WiFi inside it. Those are two different things, and they fail in different ways.
Here is how to work out which one is letting you down, in about ten minutes.
First, separate the connection from the WiFi
Run these three tests in order. The pattern tells you almost everything.
- Test standing next to the router. Phone in hand, a metre away. This is the closest you get to measuring the connection itself.
- Test in the room where it feels slow. Same app, same time of day.
- Test on a cable if any device can take one. A laptop or desktop plugged into the router bypasses WiFi entirely.
Now read the result:
- Fast on cable, fast beside the router, slow elsewhere → your connection is healthy. It is a WiFi coverage problem.
- Fast on cable, slow even beside the router → the WiFi itself or the router is the bottleneck.
- Slow on cable too → the problem is the connection, and that is one to raise with your provider.
That one distinction saves most people from upgrading a plan that was never the problem.
Why WiFi loses speed that the line is delivering
Distance and walls
WiFi weakens quickly with distance, and concrete walls, metal cupboards, mirrors and water tanks all absorb signal. Two rooms away through two walls can easily cost you most of your speed, regardless of what you pay monthly.
You are on the wrong band
Dual-band routers broadcast on 2.4 GHz and 5 GHz. The 5 GHz band is much faster but travels a shorter distance; 2.4 GHz reaches further but is slower and far more congested. A phone that clung to 2.4 GHz while sitting next to the router will report a disappointing number.
Interference from everything else
Microwaves, cordless phones, Bluetooth speakers and your neighbours’ routers all compete on 2.4 GHz in particular. In a dense apartment building this is a genuine and underrated cause.
The device itself is the limit
An older phone or laptop may simply not be capable of high WiFi speeds. If one device reports 40 Mbps and a newer one on the same spot reports 180 Mbps, the connection is fine and the older hardware is the ceiling.
The router is the limit
A router several years old, or a single-band one, will cap what it can deliver no matter how fast the line behind it is. This is a common mismatch after a plan upgrade: new speed, same old hardware.
When the plan really is too small
Bandwidth genuinely runs out when several demanding things happen at once. Two 4K streams use roughly 50 Mbps together, before anyone makes a video call or downloads anything. The signature of a capacity problem is distinctive: everything is fine when one or two people are online, and everything slows at the same moment when the household is all using it together.
If that matches your home, how much internet speed you need at home works through the numbers, and the Plan Finder will suggest a tier.
And when it is none of those
Two further possibilities worth knowing about:
- Peak-hour congestion. Fast all day, slow every evening, even on a cable, usually means a shared connection competing with the neighbourhood. Fibre-to-the-home is not contended in the same way.
- Upload, not download. Video calls freezing while downloads behave normally points at upload speed. Many connections give far less upload than download; symmetrical fibre does not have that gap in the same way.
A short checklist before you call anyone
- Test beside the router, in the slow room, and on a cable
- Check whether the device is on 2.4 GHz or 5 GHz
- Pause any large downloads, cloud backups or console updates
- Move the router out of the cupboard, off the floor, away from the TV
- Try a second, newer device in the same spot
