@Kbc if you are using any wifi connection interference can cause packet loss and therfore latency issues. If you are gaming if at all possible use a cabled connection. Video streaming can also be affected.
You mention a hub and booster which is not an ideal set up unless the two form a mesh network. Sky supply older boosters comparable with the Sky Q mesh which the black hubs supportvand tgecexpander pods which match the white Sky Max hubs. If at all possible so dont mix the two. Third party boosters wont mesh with the hubs so are not recommended unless there is no overlap in signal.
While the main cause of interference is WiFi networks within range you can also have issues with other wireless devices and any electrical device thst produces a spark or is malfunctioning like a microwave with a slight radiation leak.
