Well, CAT5e and CAT5 specify a MINIMUM set of standards, therefore a
well-made CAT5 (not e) cable MIGHT be OK if it's actually made "well
in excess".

It does make a difference, but only really once you get to gigabit
ethernet (and the faster ATM speeds.)

At 100Mb/sec you should be OK with CAT5 most of the time.

The biggest issue, AIUI, is interference on the _untwisted_ part of
the cables where the noise rejection can't happen. This untwisted
part is unfeasibly small for full CAT5e certification (like, you
won't believe how little slack you're allowed - hint: use a good
quality crimping tool.)

Regards,

Mark
