Your broadband speed can be affected by your Wi-Fi signal, router location, device, and how many people are online.
For example, your speed may drop if someone is streaming, a games console is downloading an update, your router is hidden in a cupboard, or you are running the speed test far away from the router.
If your broadband speed is still poor when testing close to the router or with a cable, your current broadband plan may not be enough for your home.
