Cat5e Computers & Internet - Recent Questions, Troubleshooting & Support

Look at the above left. There should be a plastic lever (with a little nose to hold the plug in) reaching a few millimeters out of the front panel of your hub. Press it to the body of the plug and pull it out. If the lever is broken, use a small screwdriver, a needle or a paper-clip. hth, Karl

Hey, you are dealing with high frequency - what a strange idea is this? Do you have a 100Mb/s- or 1Gb/s-network? What do you want to achieve?

Not sure if I understand your question. Cat 5 (and higher) cables consist of four twisted pairs. The idea is, that disturbances by magnetic fields compensate each other this way. I suppose that the arrangement of the wire on the plugs and jack come from good ols analogue days, where the telephone-call was only on two wires (=one pair). To keep it as undisturbed as possible, the center of the plug (pins 4 and 5 on a rj45) was used. The next pair was spread over them and therefore used pins 3 and 6. Pair three was put on pin 1 and 2, and pai four on pins 7 and 8. hth, Karl

Two equipments of the same type - two computers, two routers, two switches - should be connected with a crossover cable.

There are 2 main wiring schemes 568A and 568B the sockets should be marked somewhere with this information. You need to make sure that you use one scheme through out the network.




The pairs and pins should be noted on the sockets and you should be able to match them up using the pictures above.

Thanks

To use 8 wires cable for 100BaseTX connection only four wires are used, pin 1,2,3 and 6. You can find defective wires by using wirescope which can detect which wire has problems. If these two wires are not one of these I had mentioned according to standards 568A or B (it depends of the rest of the network) then you can use it if not then take care wher to put these bad wires but not on pins 1,2,3 or 6. Take care to document this. The best solution is to replace this bad cable with good one and do everything according to standard procedure.

These WEB sites give the wiring details of a face plate.

You have to join (connect) each color wire to wire with the same color.
Probably you need one spe?ial tool (knife) for fixing these wires into connector box.

make a cross cable find the colour code on google

how to make cross cable

My preference is to use the T-568b if there is not already a standard where you are doing the installation at. The A and B are just different standards to terminate an ethernet cable.
TIA/EIA-568-A, T-568B RJ45 Wiring Standards

To answer your question..If you want a straight through connection you would use T-568B (or T-568A) at both ends of the cable.

get a new one

I have tried this, and my suggestion is to go back and get the proper wall jack. How much are headaches worth to you? If they are worth more than the wall plate, just **** it up and get the correct one.

I'd go with CAT-6, if your building a new home. While CAT-5 would probably be fine for the near future, CAT-6 has a much higher bandwidth rating, and would be able to pass more data at higher speeds, and would in effect, "future-proof" you home network.

The future is all about high-speed data transmissions, and as more and more things are getting connected to a person's home network (Blu-Ray players, etc.) you're going to be glad that you did...

Everything is getting "smart" these days, there are even internet enabled refrigerators; while not common-place today, who knows what the next 20- to 30-years will bring...

Do it now, or re-do it in the future. The price is a little higher, but thin kabout how much more it will cost you to have the CAT-5 ripped out to be replaced with CAT-6 (or whatever) down the road...

They make some special spicer to extend your net work. But for the life of me I cannot thin of the name of them. I have plenty of them, If you want you can email me with an address and I will send you some.

Radio shack or electronics store has a tool that will crimp the modular plugs onto the network wire. Usually under 30 bucks.

Good luck!

Hi

Try a replacement or try it on someone elses PC

RJ -45 is a type of connector used on cat5, cat5e....etc cables to connect networked devices...the RJ stands for registered jack but there is really not much you really need to know about it....a RJ 45 JACK is a little bigger than a telephone jack, you'll notice the female type of input on your computer or laptop and the male end will be on the end of the cable that goes into this jack....hope this helps

I suggest soldering them, it is real easy and I could walk you through how but it would still work if you twist the together and elecrtical tape them off. Also were at on the cat 5 is it exsposed? If it is near the end you could just put a new plug on it.
