Poor WiFi connection

[DEBFT]

I have recently upgraded my broadband and the WiFi works fine in my lounge where the hub is but in my office the connection still appear week. I live in a bungalow so wouldn't have thought this would need a booster. When an open reach engineer came to resolve a connection issue he did mention that he was surprised my hub hadn't been upgraded, could this be the issue?

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.
