We use microwave broadband. There's a dish up on the roof of our shed that brings in the signal and it's a lot faster than our old BT broadband.
What I have done is buy a router that you put a sim card in and use that, mobile data but stays in the house.
Another thing I do is use the data off my phone by using the phone as a hotspot.
Neither are ideal and are relatively expensive but I want to use the internet so I will pay it.
