Hi @RGS9
If you have weak/no wifi in some rooms here are some options that would help:
1. Obtain wifi boosters from Sky as per @JimM1 post (but that may or may not cost you depending on what level of broadband service you are paying for).
2. 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. That said, once you have your own Mesh system, it will work with any broadband supplier if you eventually move away from Sky.
3. Homeplugs 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 inthe target room).
Personally I went with option 2 using Amazon Eero mesh devices as some rooms in our bungalow were just too far away from the router to pick up a wifi signal reliably. This also enabled wi-fi to reach our patio outside 😊
Hope you resolve things quickly whatever method you chose.
