Poor wifi coverage

[RoyanneWright]

Hi we recently upgraded our WiFi to a faster speed apparently. However my grandson is receiving a poor signal in his upstairs bedroom. Previously we needed a booster to rectify this issue bit the sales assistant assured me we should not need this after the upgrade. Can you please advise of any solutions. Thank you

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.
