Wi-Fi Awful for weeks and no help from sky

[simotl2020]

For three plus weeks we lose connection to WiFi and tv's drop out every day. 
Sky send open Reach out who each time am have told us something else is wrong? Unsure why this couldn't be done in one visit. After the last visit 3 days ago our wifi is now worse : I work at home and am having to now use my phone data to work as it's constantly loses signal : box been every colour of the rainbow 

sky app no help they just keep sending open reach or it tells me it's not working g at this time?!?!? Helpful! Any ideas we have never had good WiFi from Sky at our old house but they blamed the house lol we have moved and it's still poor

Neither Openreach or an ISP are actually responsible for WiFi within a property: the ISP may offer some limited (and typically additional cost) options there but can ultimately just leave the residents to find their own solutions.

The cabled broadband connection to the property is different: there an ISP can only book Openreach to investigate, and can't intervene themselves in the external network.
