Celine was having terrible problems with her network connection.
Initially I thought it was because Quickbooks couldn’t handle the
cascaded switch configuration, but with packet loss of over 50% and
only two hosts connected to the switch, it didn’t seem to be a
resource problem. The high packet loss meant that Quickbooks was
practically unusable. When I took my laptop down to the lobby for
diagnostics, I couldn’t even ping the server. The tester lit up the
lines in the right order, although one of the cables didn’t have a
working pin 1.

After some poking around, I threw my hands up and crimped one of the
spare cables according to the standards. (Good thing we had spares!)
Lo and behold! It worked! I should leave a wiring diagram in Jun’s
networking toolbox.

Does anyone have a 110 punch tool for terminating wall mounts? I
expected the wall mounts to be self-terminating like the patch panels
in the dorm, but that wasn’t the case. PC Express carries wall mounts,
but not the tool for terminating them—go figure!
