Weak WiFi in bedrooms

[Butlerhouse]

I've upgraded to sky max, and the WiFi is actually worse in the upstairs rooms in the house. Videos constantly buffering, no Internet connection in bathroom at all. What can be done to resolve this as I'm not getting what I upgraded for, actually getting less. I've done all the checks and online tools. Are sky WiFi boosters still a thing and if so how do we get one?

@Butlerhouse  If you have Sky broadband Max then you can ask Sky for a Pod which is the new booster, it should not cost you anymore as you have the Max subscription.

No , can I please have a booster

@Sarah127 

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.
