@CosminaP if thecissue is with your broadband line dropping or spedds to your hub being below the guarantee for your line either use the service checker which can book an engineer if it picks up a fault or speak to Sky. However quite frequently the broadband connection is fine and it is an issue in your home affecting the WiFi signal to your devices. Here Sky cannot really help beyond selling you a package including extenders.
