Pass Internet over phone line
I recently moved-in to a new place all wired with phone lines (there is a phone plus in each room). The thing is I don't have a land line so I thought I could use that network to pass Internet throughout the house.
I have read that 100mbps Internet uses only 4 pins, and since a phone line is composed of 4 wires, I tried connecting the "active wires" (1, 2, 3, 6) to the phone network. It didn't work, and after many troubleshooting, I realized that if only one of the 8 cable wasn't connected no connection would be detected neither by the PC nor the modem.
My question: is it indeed possible to pass Internet connection over 4 wires, and if so, how?
Thank you

Unfortunately, legacy residential telephone wiring is wrong for Ethernet in copper grade (voice grade Cat3 or worse, often untwisted), wiring topology (multi-tapped bus, not star), and often the number of wire pairs available.
A group called the Home Phoneline Networking Alliance (HomePNA) created a technology for doing residential LAN networking over residential telephone wiring, but it could never keep up with Ethernet because it had to deal with the unfortunate reality of preexisting residential telephone wiring. I believe the HomePNA efforts got merged into the ITU's G.Hn, and so HomePNA lives on as an optional physical layer for G.Hn.
