I just found the wiring in my phone lines was causing a problem with my dsl connection.. The centurylink tech rewired the dsl to our 2nd phone line (not in use for several years) and filtered the signal from the main line at the NID. I then went and disconnected the 2nd phone line from all the jacks in the house save for the one the tech set up to run the modem from and now everything fixed but I still have the bare wires from the 2nd line at the other jacks not connected.. I was wondering if I can just simply tape these up with some electrical tape of if there was a certain way I should handle them as to not make any more problems down the road. They run in a series and the modem is on the 3rd jack so can't just disconnect them.
