I’ve recently bought a new house and I’m renovating it with my parents. My father organised with electricians to run Ethernet cables to some of the rooms and to move the phone line from the kitchen to the office. They completed the works today and ran everything to one faceplate in my office but the in line is now an Ethernet port. The modem I got from my ISP requires a standard phone line to connect up, and I don’t have any adapter cables. Should I contact the electricianS and get them to redo the cabling? Should I purchase a RJ12 to RJ45 cable?
