Slow wifi in one bedroom

[stehobo]

I have an extension bedroom at my house and forgot some reason it's the only bedroom we are not getting good quality wifi. I have recently got the sky ultrafast 500 which is great everywhere else but just this one room,only getting on average about 30 mbps in there. What steps apart from the sky instructions can I do to improve it?

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.
