I have a VDSL2 connection and of course a modem. I have a Cat5 DSL RJ11 cable and I was wondering how to tweak the performance. Would it be possible to use a Cat6 or Cat7 DSL RJ11 to gain more performance from the connection? I cannot find any RJ11 DSL cables that are Cat6 or Cat6. All of them seem to be Cat5. My ethernet cables are all Cat7, though. The connection is about 100/40Mbits right now. What would be the best way to tweak and enhance the performance? Should I somehow obtain a new faster RJ11 cable, or?
