Weak to no signal in the house from Broadband - need a booster or something?

[Adrenatropin]

We have Sky Stream and Sky Broadband.

The broadband disconnects quite frequently, but the most annoying thing, there is practically no signal upstairs or at the back of the house.

You end up switching WiFi off and just using roaming data, because the signal strength is so weak.

If there anything that can be done to help with this?

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.

Thanks, I'll check out those links.

How do you know if you have Sky Q? I don't even know what package I purchased, but it's Sky Broadband and Sky TV streaming - no satellite. Assuming it comes through fibre cables?
