Re: How difficult is it to wire/crimp my own CAT5?

Seconded.  Incorrectly paired wires will sometimes work but can't be
relied upon for higher datarates.  I have fairly long cable here that
I used to use before I got my wireless network kit.  The pairs are
wired wrongly and whilst it will handle 10Mb/s, it won't work for
100Mb/s.

Some cables have four solid colours and the same four colours with a
white stripe, afair.  In that case they should be:

Pin1 - White/Orange
Pin2 - Orange
Pin3 - White/Green
Pin4 - Blue
Pin5 - White/Blue
Pin6 - Green
Pin7 - White/Brown
Pin8 - Brown
