Broadband speed vs Wi-Fi speed
Published by Pulse (SearchSwitchSave.com). Reviewed April 2026 by the UKSpeedTest editorial team led by Dr Alex J Martin-Smith.
Broadband speed is what reaches your router. Wi-Fi speed is what reaches a specific device in a specific room. They are related, but not the same.
Why results differ
- Distance and obstacles reduce Wi-Fi throughput.
- Neighbouring networks can add contention.
- Older devices or routers can cap wireless rates.
How to compare properly
Run Pulse on Ethernet for a line baseline, then run in the actual room on Wi-Fi to assess in-room delivery.
Pulse measures download speed, latency, and jitter. Upload speed is not measured in the current release.

FAQ
Is Wi-Fi speed supposed to match package speed?
Not always. Your package headline usually describes the line capability, while Wi-Fi adds distance, interference, and device limits. Expect Wi-Fi to be lower in many rooms, especially on busy channels.
Can better router placement close the gap?
Often yes for moderate gaps. Moving the hub out of cupboards, away from metal objects, and towards where people work can lift real-world throughput without any contract change.
When should I wire devices?
Wire desktops, TVs, and work laptops where stability matters most. That frees Wi-Fi airtime for phones and tablets and gives clearer evidence if the line itself is slow.
Does Pulse help with both checks?
Yes. Run Pulse on Ethernet for a line-leaning baseline, then run in the rooms you actually use on Wi-Fi. The difference tells you how much of the problem is inside your home.
