@Donna142 if you have Sky Q boxes which are losing connection then call Sky as they should either send you a Q booster or arrange for an engineer to come out.
However that may or may nit help,with other devices like your Firestick. Whether it does depends on which Sky hub you have. The older black type will work with the Sky Q boxes so they also act as wifi hot spots. Things are more complicated if you have a white sky hub as these dont work with the Q boxes and require separate extenders which can come as part of Sky's WiFi Max package see https://www.sky.com/help/articles/sky-wifi-max
