I have a box with a working ADSL Internet connection. About 40 meters away (straight), in another house, there is another, older box. There are two houses in between.
Would there be some practical way to supply an Internet connection to the older box? The neighbors are ok with us installing cables and stuff. I'd say wifi would not be practical, since the houses in between would weaken the signal too much. And using Ethernet cables might require a switch or router in between, due to Ethernet distance limitations.
