Crimper voodoo. *shudder* Glad you got it workin!
Instead of cutting across cable with a utility knife I cut the
insulation parallel with scissors and then cut the insulation away
without taking a chance with scoring the individual wires. Then I made
sure I did the wires a pair at a time, brown, orange, green and blue.
Really, you shouldn't have to remove any of the insulation. The
point of the crimper is to make the little spikes dig thru the
insulation into the wire, to make a good connection. Alignment is,
of course, critical. It also helps to hold your tongue just right
and mutter an incantation as you squeeze.
How many of the pairs does RJ 45 use?
100Base uses four wires, as two twisted pairs. The twists and the
other wires provide shielding.
1000Base uses all of 'em.
There should be some good wikipedia articles on ethernet over twisted
pair that describes this stuff.
