@Reseigh the app,measures speed to the hub if your speed is only 100Mb/s then if you click on the broadband link it should offer support to get the issue sorted if it doesnt call Sky because slow spedds over full fibre are very rare. The speed to your device is likely simply measuring the local wifi speed which is not guaranteed.
