Wifi wont work in all rooms

[Gmcn8704]

hi the Wi-Fi does not seem to be working in the back bedroom fully. 
As you went into the room it works but as you go over towards the bed to the window it doesn't seem to work chucks me off. Router is at the bottom of the stairs, And the back bedroom is to the top of the stairs is the bathroom and it's next door to that. My conservatory is furthest away from the router and nine times out of 10 I still get Wi-Fi in there. so do not understand why it's not working in the bedroom

Sky loans wireless booster hardware free under the terms of the 'WiFi Guarantee' element of the legacy 'Broadband Boost' add-on and the 'Enhanced Wall to Wall WiFi Guarantee' part of the 'WiFi Max' subscription supplement: they don't otherwise provide or sell boosters except to resolve issues with Sky Q. Phoning Sky to go through a telephone diagnosis is required to have a booster or pod allocated to the account. Inevitably some  Sky booster hardware has leaked onto a certain auction site and elsewhere online, but Sky won't offer support with using these. 

Confusingly the default 'Wall to Wall WiFi Guarantee' bundled with all new Sky Broadband orders where Boost or Max is not added by the customer doesn't actually provide booster hardware, and is essentially a sales lead generator for the supplements mentioned above plus a one month broadband subscription refund.
