icameforthefood Ok so this is a new installation.
The main problem is whether the house does or does not have a hose starting from the street cabinet (from now on : chiostrina) to the house.
As all the technicians who came seem to have failed so far, I suppose this is not the case.
This is quite weird, as from the way Italian buildings are built, this hose needs to be installed very early in the production stage.
This leads me to believe that:
• the hose is there, somewhere, but you didn't find/are not quite sure what (or where) to look for
• you bought the house in a state when the hose hadn't been installed yet
As every building is different in layout, we cannot just tell you what to do.
I can anticipate you that, a wired connection, will require at least some effort on your side (whether is finding the hose, or try create a different path for the cable).
Regarding the wireless solution, do Eolo offer you a 100 or a 30 Mbps connection? The former being a quite good and reliable connection, backed by a direct fiber optic link thus performing great. The latter... avoid it.
Regarding the wired connection:
Some images of the building from outside would be welcome, at least to try and see if it is possible to bring the connection with an overhead cable.
BTW, where are you from?
