From Mike's picture. it looks more like phone cable than cat5e to me but
that could be because all the twists have been undone - but they don't
look tightly twisted back at the insulation cut - is it really Cat5e
cable?

I'm now sure the pairs are split onto the incorrect pins of the socket.
I can see the "1" by the wh/gr and I can't work out how the opposite
corner connector could be the other half of the pair.

I suggest you get your friend back, asking him to do it properly and
show him http://www.surrey.ac.uk/eng/Intranet...upport/UTP.HTM The
wiring of the socket is at the top. (and you'd think someone at
surrey.ac.uk would spell correctly...) Don't forget to check he cuts off
the tiny piece of each wire at the end that was used in the punch-down
connector, so he is connecting to a fresh piece of wire - and get him to
fit a tie-wrap as a strain relief.
