Poor connectivity in part of house

[JAMIECATTELL]

I recently installed two ring doorbell cameras. the front door bell ( furthest from router) has no connection. Since installing doorbell cameras i have lost internet connection on tv ( through Sky Q box) and phone connection is poorer than it was when away from the router in the house. Do i need a booster to get full connectivity ? or can Sky internet be set to increase wifi signal arround the house

Sky loans wireless booster hardware free under the terms of the 'WiFi Guarantee' element of 'Broadband Boost' and the 'Enhanced Wall to Wall WiFi Guarantee' part of the 'WiFi Max' subscription supplement: they don't otherwise provide or sell them except to resolve issues with Sky Q. Inevitably some have leaked onto a certain auction site, but Sky won't offer support with using these. 

Confusingly the 'Wall to Wall WiFi Guarantee' doesn't actually provide booster hardware, and is essentially a sales lead generator for the supplements mentioned above.
