I was like your mum, didn't understand the internet at all. I am with BT Broadband and I have no complaints at all about them. They came and installed the home hub and showed me how to work it, and activated wifi for me so I can use it with my laptop. Yes someone has to come in but they do it by appointment, they check your wiring and bring extra kit into the house. It didn't take long to actually install it - as I recall, it was about 3 weeks from order to completion.
