I am doing some rewiring of our internal phone lines (almost entirely removal of unused lines). The issues we have run into is the router will every now and then simply not connect from the house to our provider.
The wire from the NID to the router is an old, very thin 4 wire phone cable (GRBY wires). I am going to replace it whether it is the culprit or not. The outer sheath is getting brittle.
The plan is to use an outdoor UV gel filled Cat5e to go from the NID to inside the house, then Cat5e from a box there to the router (or maybe just gel filled all the way, it's a fairly wet basement). This is an old house and the cable will run near and across many power cables.
Given the possible interference would it be worth it to double up cables from the NID to the router (i.e. use blue/blwh together for ring and orange/orwh together for tip)?
I'm not exactly clear how the twists work with data communication so maybe it would be better to use blue/orange and blwh/orwh instead?
Would this even help with possible interference or signal strength?
