@Debbie401 wifi can be a problem and for any crtical work ethernet is a far better connection. However you can do things to improve WiFi . Make surecyour Sky hub is not on the floor or worse under other kit. Wifi signals are like light so pkacectge hub on a table or shelf so thecsignals are not blocked by radiators and other kit. A lot depends on the layout and type of construction of your home and how many neighbour's networks are within range as interference is a very common issue.
