@Anna_1602 your home might becsmall but if it has solid brick walls internally it can be very difficult to network using WiFi.. You maybe able improve things by making sure the hub is on a surface out in the open so it is above obstructions like radiators.
Sky can supply extenders if you buy their WiFi Max package https://www.sky.com/help/articles/sky-wifi-max but in buildings with solid walls that system is not thst effective. There is third psrt equipment you can buy powerline adapters are one solution that can work as tgst uses mains wiring to carry thecdata.
