@Dominic4 very coomon issue as in many properties due the layout and type of cinstruction you need more than a single wifi source to get coverage in every room. Sky will sell you their WiFi Max package which can supply up,to 3 extenders see https://www.sky.com/help/articles/sky-wifi-max or you can buy your own wifi equipment and use that.
