@MattM96 wifi speeds can vary due to interference and simply byba device moving a few feet. Not sure what speed you normally get but as signal strength drops as it passes through walls etc it impliies you may need to think about getting a better WiFi networkto improve coverage in that area.. 40Mb/s is above the 25Mb/s speed guarantee Sky's WiFi Max bundle offers so you maybe best advised to think about buying a third party mesh WiFi system. These use multiple wifi sources working together to giveca more reliable network.
