Hello @Hamish123
Wi-Fi is probably the most common issue raised with any internet provider as a single router is often not capable of covering the whole property. I am not an expert in this but have experienced the problem of wifi not reaching all rooms as we live in a bungalow with the router at the front of the property (cannot easily be moved) so rooms at the back were black spots.
If you can't get help from Sky with boosters as per @caesarome's post then two other options are:
1. Invest in further hardware and create your own wifi Mesh with sufficient devices to cover the whole house. There are multiple suppliers you can pick from that all work well, but this can be relatively costly (however once invested, a Mesh system would work with any broadband supplier if you eventually move away from Sky).
2. Homeplugs/Powerline devices can provide a hardwired solution from your Sky Broadband router to other rooms using your mains wiring, you simply need a power socket near the router and another in the "target" room that then allows devices to be hardwired (or connection of a wifi hotspot in the target room).
I went with option 1 (4 x Amazon Eeros), which also made wifi available on our patio outside which is great for the summer. This worked flawlessly when with TalkTalk and also since moving to Sky last August. Hope that I haven't jinxed it !
Good luck whatever you decide to try !
