@Daniel281076 incredibly common issue as in many homes you need multiple wifi sources to get usable WiFi in every room. Wifi signals lose strength passing through walls etc the denser the wall the more strength thst is lost. Make sure you hub is not losing signal unecessary so endure it is out in the open on a surface above obstructions like radiators.
Sky will sell you their WiFi Max bundle which can supply up to 3 pod extenders if required see https://www.sky.com/help/articles/sky-wifi-max or you can buy your own equipment if you prefer.
