We moved router today. Before it was moved it was working. this is the second router which connects to another one, which I will just call the first router. Once everything was set up and plugged in, they were not talking to each other, I went into my D-link's menu at the FAST ETHERNET VIRTUAL CABLE TESTER menu. It said TX pair 63M and TX receive 63M. Does this mean that the cable is broken at 63 meters? We had two cables, first is 200 feet connected to a 100 foot cable. I know that 300 feet is the max length so maybe it was just a bad overall connection. 63M works out to 189 feet which would put the break at the end of the brand new 200foot cable. Which as i said was working fine before. the 100foot cable, I don’t know where it came from, has electrical tape covering cracks and has been bent in every which way. so I would assume that if something was broken, it would be that one. Its working now, we tested both cables, both work. put the system back together and it all works now. So the way I see it, its either a length issue, or there is a break in the cable somewhere and moving it has somehow gotten contact back at the moment.
I say, replace the cable... or at least splice a new cable into the section that is worn out / used. And I do believe there is a ethernet cable tester device that tells you the status of all the twisted pairs in the cable. And I doubt its reporting to the area that is messed up.
It might be able to tell you that a cable is messed up, and it might be able to determine the length at which the problem is; although it's very unlikely imo, because we're talking about accuracy of 10ths of microseconds for a measuring device, and although you do have a very accurate clock in any computer, calibrated measuring devices like that are pretty expensive. And it certainly won't be able to tell you anything if the cable has snapped, other than it's snapped.
thanks guys thats kind of what I figured. doesn't matter now anyway as one of our amazing helicopter engineers drilled into the cable.... Now we need a new one regardless.
There is a special tool... Happened to me when we renovated, my internet would not work so my friend came over and brought a small box machine thing. Basically you plug the ethernet cable into a wireless receiver thing, and then go to the other end of the cable and plug it into the main box, then press the "test" button and it sends a signal, if the wireless receiver gets the message, the box beeps or has lights that go on, which let you know the cable is transfering data. Not sure what its called, but at least such tools exist.
I think you mean a LAN cable tester, which isn't wireless It runs a signal down the cable to ensure a) the cable is intact, b) to tell you what type it is i.e. Patch or Crossover
I used to use one of these. They rock! They'll tell you how far down a cable the break is. They do dhcp, so you can tell if the port you plug into is hot or not, and will do the normal cable testing.
