| 1442605 | 2017-11-26 18:46:00 | We have in the last few days had fibre installed, download speeds have gone from about 4.8 Gbs on ASDL2 to about 101 Gbs. My problem is that the computer, and the modem are in a bedroom/office, and in the adjoining hallway. At the moment they are connected by a Ethernet cable 5 metres long on the floor. I want to connect them via two flush boxes in the walls, and have all the jacks, flushboxes etc. required, but cannot' make it work. The cable that I am using is a cat 5e, and I have been wiring it into the jacks as a cat 6 cable. I have tried connecting both ends as cat 6, and with one end cat 6 and the other cat 6 reversed. I haven't tried cat 5e connections because I cant find a description. Can anyone help? | Brucem (8688) | ||
| 1442606 | 2017-11-26 19:14:00 | For starters, you have the speeds wrong, no way is ADSL2 going to give you 4.8Gbs, and certainly not 101, Mbs maybe. The cabling-- if its not working then you have it wired incorrectly OR there's a break in the cable. Wall jacks will have a colour code sequence on them. The wiring must be correct, all it can take is to have 2 wires wrong ( cant have only one) and it can stop/cause problems. Make sure the wires are pushed in fully as well, and set to straight through. The Ethernet cables in your case should also be straight through as well. Look up the wiring code and make sure you use a straight through option. 568B Standard 8446 Seen countless times that people simply put the wires how they like and while if they are straight through setup, makes is difficult to fault find if not in the standard order. Normally when I hit that I cut off the plugs and rewire the standard way. :) If you are going to be making cables, then it also pays to invest in a cable tester, they are not expensive and will test to make sure the wiring is correct. |

| 1442607 | 2017-11-26 19:23:00 | I have tried connecting both ends as cat 6, and with one end cat 6 and the other cat 6 reversed. I haven't tried cat 5e connections because I cant find a description. Can anyone help? Whether it is cat 6 or 5, makes no difference to how the wires should be. I have my old cat 5 cables still in use, these ran under the house then back up through the floor to modem and pcs, all I did was plug them into the new modem instead. (Wiring them, meh) But as Wainuitech says, get your colour code right.... |

| 1442608 | 2017-11-26 20:16:00 | Wire it like Wainuis' diagram, the pattern is more important than the actual colours though. What I mean is, each set of pins for a pair of wires must be connected to a pair, not split between two pairs. So 1&2 - pair 2 (orange) 4&5 - pair 1 (blue) 3&6 - pair 3 (green) 7&8 - pair 4 (brown) The pair numbers aren't important, that's just my days as a tech coming back, the colour code Blue, Orange, Green, Brown, Slate(grey) is burnt into my memory so to me blue is always the first pair. If you mixed up any of the pairs it doesn't really matter - as long as it's the same at both ends. But if you split a pair by say putting it on pins 3&4 (which would seem logical but is wrong) it will not work. For GigE the data is broken into multiple slower signals and each pair of wires is used in both directions to send a signal. 100M ethernet is much simpler and uses the blue and orange as send and receive and is more likely to work on a partially correct connection, however Gige adapters detect each other and will not automatically step down to 100M. A bit of useless trivia perhaps, but I've used an old 100M switch on the end of a cable that only had 2 pairs to force the connection down to 100M and make it work when it wouldn't with the PC and router connected directly because they were both GigE. |

| 1442610 | 2017-11-26 21:03:00 | How about using the house wiring with power-line adaptors? | mzee (3324) | ||
| 1442611 | 2017-11-26 21:30:00 | If you've got a smartphone put Electrodroid on it. It'll show you nearly every pinout (it has diagrams as well) for whatever cable It's only a few $ to buy it | Speedy Gonzales (78) | ||
| 1442612 | 2017-11-27 01:44:00 | I have removed the jacks from the ends of the Ethernet cable (approx 7 m long) and tested each wire for continuity. I dismantled each jack, and tested that I had continuity between the pins and the wire holders. I tested each wire in each of 3 patch cables for continuity. I could find no problems. I reassembled it all wiring both jacks identically: pin 1: Orange/White, pin 2: Orange, pin3: Green/White, pin 6: Green, pin 4: Blue, pin 5: Blue/White, pin 8: Brown, pin7: Brown/White. These pins are in order of down one side and up the other. It still doesn't work! Where do I go from here? | Brucem (8688) | ||
| 1442613 | 2017-11-27 02:22:00 | How are you pushing in the wires ? They need to be fully seated, some Keystone /Krone connectors can be a bit touchy. Also Krone connectors you can wire in a different layout both 568A & 568B. The picture Below I wired in 568B, notice the A & B on the connector. Should look like this when seated: 8452 To do that the best way is with either a correct punch-down tool which has a inbuilt trimmer, or at least an el cheapo, as pictured, the cheapo is the on on the right: 8453 To test if the wires are connected correctly use best to use a tester, this is mine, when plugged in if all the wiring is correct the lights flash from top to bottom in sequence, if any are dead or incorrect then it goes out of sequence: 8454 Theres instructions / Video on this page HERE (www.thatcable.com) If everything is as the pictures /video then you may have a faulty jack/connector. |

| 1442614 | 2017-11-27 04:24:00 | I am using a thing called "Economy UPT Stripper" purchased from Jaycar. It looks as if I have to buy a tester. | Brucem (8688) | ||
