I'm looking for clarification, I have Verizon dsl, my internet connection kept dropping off, one of the their techs said to use cat5e or 6 cable from the interface box to the modem/router, he said use the twisted pair wires together just be consistant with colors at each end, another Verizon tech said no, you have to separate the wires and use only one strand of the pair just regular cat3 phone cable, can you tell me which one is correct, thank you
