two story house, dsl router is upstairs. needing to get internet downstairs. entire house is wired with cat5 cables using old phone jacks, i get that i have to wire rj45 ends to replace the phone jack ones. but when it comes to wiring the NID im so lost. opened up the NID box and it has two wires from street to NID ( blu and blu/whte and from there it has two wires (same colors) going into the house (my master room phone jack to dsl router)...how would i be able to make this happen if at all possible. the NID box is the newer ones that have a closed lid where both blu and blu/whte wires meet inside it. wireless router wouldnt be an option since materials used to build the house kills the wifi signal throughout the house.
