In addition to what the others have said ( incorrect patch cables );
can you unscrew the face-plates, and either take a picture or describe
what wires have been punched down into which terminals?

I'd expect it to be:

1 Orange / White
2 Solid Orange
3 Green / White
4 Solid Blue
5 Blue / White
6 Solid Green
7 Brown / White
8 Solid Brown


Er, well then, you'd be wrong to expect that.

The TIA 568B standard (almost universal for UK structured cabling
installations) for an RJ45 connector is based upon the Western Electric
Colour Code, as follows

1. White/Orange
2. Orange or Orange/White
3. White/Green
4. Blue or Blue/White
5. White/Blue
6. Green or Green/White
7. White/Brown
8. Brown or Brown/White

In all cases where two colours are shown, the first colour is the main
colour and the second colour is the tracer (or stripe) colour.

However the latter differs from the former only in the sense of colors.
As far as the electricals go, it's pairs in the right pairs of
terminals, so will work just as well.

AS I said before' all that matters is a pair on 1 nd 2, a pair on 3 and
6, a pair on 4 and 5 and a pair on 7 and 8. Which way round they are, or
what colors they use, are actually not a problem.

In fact for ethernet up to 100Mbps,only 3 and 6, and 4 and 5 need be
connected at all..
