@Julielivingston if you do not want help from the community why post in the first place? You need to call Sky them.
Before you do consider that Sky cannot directly control wifi speeds in your home that is down to you. You can test the speed your TV is connecting at by running the Network test in the Get Help menu in the Netflix app. To stream video you may need to pay for a better WiFi connection either by buying a Sky add-on or your own equipment.
