Wi-Fi versus broadband
A clear diagnostic guide to tell whether slow internet is caused by broadband or home Wi-Fi.
Use case: Identify whether the line or the home network is limiting performance.
Part of Wi-Fi and networking. Use the hub to compare related problems, tools and buying routes.
Broadband is the connection into the property. Wi-Fi is the local radio network. A slow result on one does not prove the other is at fault.
How to use this guide
- Test beside the router, then in the problem room.
- Repeat over Ethernet if possible.
- Compare time of day and more than one device.
- Only then decide whether a package, router or mesh system is relevant.

Frequently asked questions
Can a new package fix bad Wi-Fi?
No. A faster line may leave an in-home coverage problem unchanged.
