I have a CAT6 ethernet patch cable running about 65m. I can't get connectivity and I think it's because the cable might be too long. I know the LIMIT is 100m long, but I can't figure out what else might be the problem. I tried two different machines to test the cable and neither got connectivity, so I got a switch and hooked that up and the little green connection light didn't go on. I made sure the cable was not broken by sending power down it with a power supply and reading the voltages on the other end and everything was ok. This leads me to think that the problem is either with the cable termination or the length. I tried changing the connectors for both A and B standard. They are really hard to put on, so it's possible I'm not doing it right, but I tried a billion times and Im getting really tired of this. Any suggestions?You got the ends wrong. Make both ends type A.
Do coypu have the right tools to do the cable ends?
Where you BOUGHT it sou hso have the tester for testing all 8 wires.
Something like this:

Or this:

Those on on eBay listed under :
Computers/Tablets & Networking > Cables & Connectors > Cabling Tools
About $150 plus shipping. The tester is worth havering. Save you hours of work.
Well originally I had both ends type B and tried changing one to A. It's hard for me to undo to other one because the connector wasn't working so I just soldered the wires together. Do you really think that's the problem? And no, I don't have any tools except the connectors and a wire stripper.Without the right tools it is hard to do.
So you soldered the wires into the devices?
Do you have a picture of what yon did?
Reading your response post, Yes soldering the wires together will cause no communication to happen.

Also, as you said you did not have any tools other than the connectors and wire stripper; The connectors require a "CRIMPING tool" which crimps the connector to the wires, and connects the internal cores of the wires to the plug connectors. There is no need to strip the wires from the cores themselves. This crimper tool is the tool shown in the image posted by Geek-9pm with the green handles. A local JayCar store will have these.

The only bit that needs to be stripped is the outer jacket by an inch or so, then trim the end of the cores so they are all identical length. The length the cores need to extend past the outer jacket is about the length of your thumbnail.

Unfortunately in your case you will need to cut the end connector off if you cannot get the connector to come off.Yeah, I don't have one of those tools, I thought I could do it without. Also these are probably not the type of connectors you are talking about. I am talking about the female connectors that you use in a wall plate, not the kind you plug directly into your comp.

No, I'm not that dumb. I meant I soldered the wires to the wall plate connector (In the proper configuration (or so I thought), not just a random mass of wires).

So I'm going to try getting the normal connector that you plug into a comp instead of this wall plate connector and then use the tool that you talked about. I don't think that tool will work the same with the wall plate connector. I'll just have to ignore that I have a cable through a hole in the wall instead of a proper plate.
