My house is prewired for ethernet in multiple rooms of the house. I had a tech come out to move my modem down to the central panel to connect into the modem and make each of the drops in each room hot. He connected the modem and got internet at the modem but could never get the drops in any of the rooms to work. He said he could only get one of the rooms/drops to work at one time but each of them works individually when the other two are not connected. Something like 2 pairs work but the 3 pairs will not and might be unbalanced, etc. He and I both agree it was strange and said I needed to get an electrician out. Has anyone had this issue??
