RJ45

You should be using 568B, not many people will use 568A and its annoying when you run into a case that it is used in (in my experience AT&T techs will do it all the time)

Do those work interchangeably? The only ones I've made are A and that works but another cable from my dish is B.

As long as both ends are the same it doesn't matter much, unless you go completely off the rails and do a random order, then it could reduce range/speed of ethernet over longer distances.

 

If one end is A and the other is B which you have made is a cross-over cable and most modern routers/switches will use it anyways. But its generally for connecting two computers directly together.

Cat6 cable, RJ45 connectors.

 

What connector type should I be using to make gigabit patch cables?

 

Thank you all very much! Very helpful! :D

Make sure to get RJ45 connectors with the load bar.

Is it possible that some modems wont work with 568B, because I've tried to make about 5 cables, using CAT6 cable, using the correct wire order, and none of them seem to be working.

 

Can you think of anything that I might be doing wrong?

 

Thanks.
