Since I've just finished rewiring my under-stairs cupboard for phone & broadband and installed my new VDSL router/modem, I'm wondering if there's any point worrying about the relatively short 1 metre modem cable that looks too flat to have any twisted wires within it. Should I worry or would any gains be insignificant? Currently on FTTC with Plusnet and I have the newest master socket with adsl modem socket & built in filters. Tim
