The wire sequence should be the same at both ends of the RJ45 connectors.
You need a tester that has a remote that you plug into one end of the wire
and the main unit plugs into the opposite end. The screen will show you if
the wires are correctly connected at each RJ45 terminal. The Home Depot
sells them. Mine is made by Ideal. If you don't want to buy the tester you
can try using an magnifying glass and see if you can trace the color coding
at each end and make sure it matches left to right at each end. Go on the
web and get a diagram of the wire color coding and make sure you follow it.

Good Luck

Subject: [PCBUILD] hard wiring issue

I'm running about 75 feet of cat5 with a standard RJ45 termination block at
each end.  
I'm using the straight-thru wiring, wh-gr, gr, wh-orange, blue, wh-blue,
orange, wh-brown, brown on each box.  Should I be reversing the colors on
one end?    I have both ends wired in the same sequence.
When I plug in a laptop through the new cat5 with a patch cable at each end,
I can't get an internet connection.
I plug the laptop into the existing jack with either patch cable, works
fine.   I checked both patch cables with a cable tester, the tester also
shows 4 good pairs.  Kinda hard to test the 75' run after it's installed
through the walls, etc.
