Internet speed
What is a good internet speed?
A good internet speed is the one that covers what you actually do at the same time, with a little room left over. For one person browsing and streaming a single HD screen, 25 Mbps download is comfortable. For a household with two people on video calls while a third streams 4K, 100 Mbps down and 10 Mbps up is a safer floor. For a large household with several 4K screens, cloud backups and a working-from-home day in parallel, 200 Mbps and up starts to make sense.
Bandwidth is only half the story. Latency — the round-trip time to the server, measured in milliseconds — is what makes a connection feel quick or sluggish. A 200 Mbps line with 80 ms latency feels worse to use than a 50 Mbps line with 12 ms, particularly in calls and games. That is why the internet speed test reports three numbers rather than one.
| Task | Download | Upload | Note |
|---|---|---|---|
| Browsing and email | 5 Mbps | 1 Mbps | Anything above this is comfort. |
| HD streaming, one screen | 5–10 Mbps | 1 Mbps | Netflix suggests 5 Mbps for HD. |
| 4K streaming, one screen | 25 Mbps | 1 Mbps | Multiply for every screen at once. |
| Video calls | 8 Mbps | 3–5 Mbps | Upload is the part that breaks calls. |
| Online gaming | 15 Mbps | 3 Mbps | Latency matters more than bandwidth. |
| Cloud backup | 25 Mbps | 10 Mbps+ | Large uploads are limited by upload speed. |
Why your result is lower than the plan
Providers advertise "up to" speeds measured on a cable, with nothing else running, often at an ideal time of day. What arrives at a browser is reduced by the wireless link, the router, the network adapter, other devices in the house, a VPN, and contention on the street. Testing on Wi-Fi and again on a cable separates the two: a small gap means the line is fine and the wireless side is the problem, while a gap that stays in both means the line itself is delivering less than expected.
Before you upgrade a plan, fix what is already there. Moving the router out of a cupboard, switching from 2.4 GHz to 5 GHz, replacing an eight-year-old router or adapter, and stopping background sync and backup all recover speed that a bigger plan would not have given you. If the connection drops entirely rather than simply slowing down, work through Wi-Fi connected but no internet instead — that is a fault, not a bandwidth problem.
And if pages load slowly while the speed test looks healthy, the browser is usually the culprit: see why your browser slows down.
