The problem with the wifi "by air" is the bandwith, it is restricted to get signals to the box, the more people use it the worse the signal gets it devides the time for all the connections.
The best way is hardwired through coax or better fiberoptic. The fiber goes into the house to the wifi-router. All connections by air are only for low speed. It is good if you live in the mountains and there is no phoneline but thats it.
My neighbour has a phone and internet connection provided by Movistar, so over the phoneline he gets 10 megabit, no problem what so ever but it depends on the distance from the central point to the house. Higher speed like 25 50 or 100 megabit is not available on the phoneline here in LM.
The wifirouters password is usually available, the provider normally has a backdoor. You also need the password to change the settings if you use a security camera, you need to open a special port to use it.
Prices are also high in Spain compared to Holland where I live, I pay 23 euro a month for 2 phonelines and a 22 megabit connection, fiber is not available where I live but where it is, speeds to 300 megabit are available for a reasonable price.
