@Malwinder if you have bought Sky's Broadband Boost or Wifi Max packages call them to get a booster sent out which might help.
However if you havent you can buy third party kit for less than those packages cost over a year. If the room is quite distant from the hub and you need decent speeds perhaps to use it for work or gaming then consider buying a Powerline Adapter kit thst uses the mains wiring to carry the data to the target room. Many different types but plan to get roughly 30% of the rated speed on average. You can buy these units with built-in wifi access points but if gaming or working using an ethernet cable from the adapter to a la-top or console would be better.
Another solution is buying a whole home wifi kit these are not cheap but should give bettercwifi through out your home. If you think this maybwork for you post back with details of the Sky product you buy and the system you have decided to choose - prices vary widly.
