That's a good reference, but it appears to be old. The color code I
detailed in my last post was the "B" standard. Either one works equally
well, but you will find that people tend to use B more, so you are
better off learning it. That article also says that the unused 4 wires
aren't important and can be left out. Which technically true for 10/100
connections you will need to make sure they are wired and correct for
both gigabit connections as well as power over ethernet (POE).
I've had to deal with a handful of places that just wired everything
with the same colors on both ends. The installations were usually done
by electricians who were never trained in low voltage data cables.
While the colors and size (as long as it's as big or bigger) don't
matter in electrical work from a technical standpoint, they are there
for a safety reasons so you don't electrocute yourself or start a fire
the next time someone works on your house, but other than that it could
work it's entire life wired with the wrong colors. With networking the
type of cable and the color pairs you use within that cable matter quite
a bit. With the installations that I have delt with all sorts of
problems come up. The cables will appear to work OK, although you won't
ever get top speed with them, but they are throwing so many errors that
a lot of (cheap) switches will have to work overtime having to deal with
your bad cable and just lockup and need to be reset, or in some cases
burn themselves out. You will also find yourself trying to fix things
that leave you scratching your head and wondering why it isn't working
right, or why it sometimes works and other times doesn't, or even works
for a while and then fails.
Bad cables cause the worst type and most frustrating of failures. It's
much easier to fix something that is just plain broken rathar than
something that sorta works.

you forgot the link but I guess it is the cable. I had a long
enough cable to just connect it without it looking pretty and it
worked. I don't know though. My connections are good (I think) so
maybe it is the cable itself. That is all I can think of.

I would take a gander at this link, and look at the various
diagrams. especially the notes at the end.

okay, I thought I did it correctly.... I mean the modem is
lights when I plug the new cable in but my brother tells me
that he still isn't connected and his box (windows) won't
ping google. You just need to make the pairs alike on each
end, right? I answered that question by looking at a known
good cable. I just replaced the rj45s and same thing. I just
restarted the ms box and after it started the front network
computer icons lit up. Then I tried to renew the IP but it
failed. Then I left and came back to the computer and there
was a bubble message that said it was connected but still
couldn't get any pages to load. Then I disabled the
connection and reenabled and it said it connected. What's
going on?

No, Just crimp it the conductors on the RJ45 jack
will pierce the insulation. If you have stripped
it, it will probably short inside the plug.

I feel retarded..... I can't remember if you are
supposed to strip cat 5
to the copper before you crimp it. I'm thinking
no but I need to make sure.
