Does all your cables have 2 pairs of wires or 4 pairs of wires, and are
they properly pinned out ?

Even in purchased cables, I have seen such faults (especially cheap/no
name) cables, where the pins for 100Mb are correctly pinned out, but the
other 4x wires are not.

Are they hand terminated, did the pins crimp down properly etc ?
It's not uncommon to have faulty raw plugs, or crimp tools (eg that scar
the edges of the plastic channels - making the copper fingers be unable
to make contact).
