I am just smart enough to be dangerous, so it was no surprise when I could not get my computer to talk to my router that I spent 8 hours over a couple
days trying to figure it out.
I have had some problems in the past with Cat-5 cable (I make up my own to save $$), but nothing like this. Usually if I have a bad connection, it is
because the end was not crimped properly or I might have a wire crossed on accident.
This was not the case.
The router had worked fine for a couple years, and although I am on a new network and modem, I have the configuration down to a fast procedure so I
can browse the net with my caffeine fix in hand in no time. The fact is, I had the network up and running for a week or so, and then the moment I
installed my permanent ethernet line, it quit working.
Usually, I can disconnect a cable, and reconnect it and the computer will reacquire the signal and settings, but not this time.
I made up several cables to try them out with no luck. Finally, I brought my whole rig down a flight of stairs and set it up next to the router and
modem and other computer using factory made cables, and it worked perfectly. Then I switched it with my cable and it still worked great.
I thought I was done. I next ran my 'tested' cable back upstairs, through walls and floors, you name it - all 60 ft. of it. Then it still won't
connect, but it just did before an hour of installing a permanent line.
Now I am frustrated and about to buy a wireless router.
After a couple days of thinking about this, I finally went online on the working computer and did some research.
I have always made my cables for the router as "straight through" cables. Each pin/color is the same on each end. To my mind, it made no
difference of which color went where as long as the ends were the same, much like a telephone line - but that is where I was wrong.
Since the wires are twisted pairs, you must split one set of wires between pins 3 and 6 in order to stop interference in the signal over long
On a short cable it probably won't matter, but over 60 ft, like I have you will definitely have problems.
Well, I learned something today. I still don't know it all, but I did learn one more thing than I did yesterday.
