Do you have a really long cat.5 cable laying around with no ends well if you do I can show you an easy way to use that long cable for a really long high speed ethernet cable.
Step 1: Get the Stuff!!
you will need the following
One standard lenghth cat. 5 ethernet cable
The stock cat. 5 cable of your desired length
Pin nose pliers
knife of some sort.
Step 2: Cut the Standard One in Half Cleanly
Just fold the short cable in half and cut it with clips or a knife.
Then cut off about an inch of the insulation off both cut ends.
Step 3: Clean Off the Ends
Expose each individual wire on every end of all your wire ends.
Just enough to twist each together
Do the same to your stock wire
Step 4: Now for the Splicing
You have to match the colors on each wire and twist them individually. ( if you want you could solder each wire but that would take a lot of work)
There is a chart of the colors at the bottom of this site.
There is a couple wires that are hard to tell what they are.
When you twist one together use electrical tape to shut it off or you could fry something maybe....
Step 5: After Doing Each Side
now rap the whole but off your twisties together with a good amount of tightly wound electrical tape
Step 6: Test It
Test it on something that isn`t as important so it doesn`t mess something up.
I am not responsible for any shorts that probably has to do with matching the colors wrong...
