I have one 4 pair cable. The brown pair is being used for a telephone (that is working). I took the green & orange pairs and punched those down to a CAT6 block and added a CAT6 connector at the wall alongside the existing phone.
My new (confirmed working) network tester is showing that pins 2 & 6 are connected. Pins 1 & 3 do not show continuity. If I move the solid G or O wire to different pins those show as continuous.
So, from wall to basement I have this:
Cat6 punch down adapter (T568A confirmed) using G/O pairs. That runs to the basement (toned out the correct cable) and the G/O pairs are punched down (T568A confirmed). From punch down block it runs to the back of an Airport Extreme Base Station (AEBS).
I understand this connection will only be 10/100Mb and that is fine; this is just for a roaming wifi network setup. Also of note; my Mac does recognize the cable and reports that it is 10Mb.
Also of note; I have used this wiring scheme with success in the same env. The only difference is that that line is using all 4 pairs (1000Mb)
My Mac shows that it is sending but not receiving any packets.
I've tried different (pre-made) cables and different punch down ports / adapters.
I have tried connecting the Blue pair as well with no change. Halp.
