Poor WiFi in back room

[MattynoMates]

I have recently moved from Virgin Media to Sky. Since doing so I am getting poor WiFi signal in back room (2 outside walls between Sky puck and router). The Sky engineer suggested I ask about a Sky WiFi booster "pod". Despite being upon Full Fibre 500, just checked WiFi speed in back room using Fast.com and typically  only getting 9 - 15 mbps. How do I get a Sky WiFi booster?
