@Zoe2705 Wifi signal levels in your home depend on the layout, type of construction and the level of interference so every home is different. Doirbell cameras are a common issue as they are often screwed to an outside wall with a double thickness which is almost guaranteed to have poor wifi!
You can help yourself by making sure your. Sky hub is in the best position which is out in the open on a surfacecabove obstructions like radiators. Beyond thst you may need more equipment to get decent WiFi speeds in every room. There are a buge number of possible solutions what you need depends on the problems your home poses.
