1000Base-T specification supports the use of Cat 5, enhanced Cat 5 cable, for gigabit transmission. Cat 5 unshielded twisted pair cable contains four twisted wire pairs. Fast Ethernet 100Base-T and 10Base-T use only two of these pairs, leaving two pairs unused. Gigabit Ethernet 1000Base-T uses all four pairs. |

reply to trparky Should do, if it's in good shape end-to-end. |

reply to trparky IIRC, CAT5 cannot, but CAT5E cabling can do GigE speeds. Check the labeling on the cable / box to be sure what you're getting. Regards |

reply to trparky Correct, gigabit was designed so Cat 5 can meet the specs, but Cat 5e was designed for gigabit. Mind you, no new Cat 5 equipment has been made since 2001, so most of what you find is Cat 5e. -- I tried to remain child-like, all I achieved was childish. |

Yeah, I know but I have a 50 foot CAT5 cable running down the middle of my house that links the attic to the basement. I could replace it but if I can get away with not replacing it, it would be easier on me. I'm only running 100 Mbps right now but with all of the files that we throw about the network, 100 Mbps just isn't cutting it anymore. -- Tom Boycott AT&T uVerse! | Tom's Android Blog | AOKP (The Android Open Kang Project) |

No reason to replace it. /tom |

Then I may have to redo the connectors on the end of the cable. one of the connectors has been through hell so I'll redo the connector. I have the connectors here and other tools to make the ends and the test equipment to test it with. -- Tom Boycott AT&T uVerse! | Tom's Android Blog | AOKP (The Android Open Kang Project) |

reply to trparky How much would you have to rip up to replace the cable trparky  ?If you need the reliability and peace of mind, I'd replace with cat5e / 6. Less headache / heartache that way... My 00000010bits Regards |

reply to HELLFIRE I'd have to rip out a couple of staples, cut a connector off the end, electric tape a new wire to the end of it, and then pull it up through the same hole clean through the middle of the house that's in the house from the basement to the attic. The hole in the middle of the house is where the water pipes for the restroom up there goes through. That and a lot of electrical wires too. -- Tom Boycott AT&T uVerse! | Tom's Android Blog | AOKP (The Android Open Kang Project) |

For 50' run, I'd not worry about it. The update of the original requirement for CAT5 up to CAT5e was added as it was found the S/N was marginal on 100M runs (328'). And, that was biz apps with lots of equipment. In a residential setting, I'd expect regular CAT5 to be good at 150'. However, you mentioned staples, improper use of those can degrade the cable significantly. -- Scott Henion Embedded Systems Consultant, SHDesigns home - DIY Welder |

Well... I guess I'll try running Gigabit on the current wire and if the cable doesn't work, then I'll replace it. |

I do have a line tester but it doesn't do any kind of really fancy testing. It just tells you whether or not the cable passes which includes testing to tell you if you have the wires mapped correctly at both ends. All I have is this...

In my case, it's a home network that I'm just trying to upgrade to modern standards. I'm trying to do this with as little expenses as I can. I know you can't cheap out but at least this stuff has come down in price since it was years ago. Gigabit switches, even those for home use, were nearly $100 years ago. Now you can find one for under $40 on Amazon.com. NETGEAR GS105 ProSafe 5-Port Gigabit Ethernet Desktop Switch - 10/100/1000 Mbps If I get Gigabit running on the existing wire, great. If not, I have CAT5e wire ready for use. All I have to do is cut it to length, puts connectors at both ends and I'll be done. I'd just rather not do it if I don't need to. -- Tom Boycott AT&T uVerse! | Tom's Android Blog | AOKP (The Android Open Kang Project) |

I'm getting about 800 Mbps across the CAT5 wire. Run "netstat -e" from a command line after your computer has been running a while. Does it report a high number of send or receive errors? Some errors are to be expected, but a high number can indicate a cabling issue even with the 800mbps that you're getting. |

I used to be only able to copy files between my computers using Windows File and Printer Sharing with the aide of TeraCopy at a maximum of 10 MB/s. Now, I can reach speeds of 90 MB/s.

It auto-dropped to 100 Mbps. I guess that the link isn't stable enough to maintain 1 Gbps and that it auto-dropped to maintain link status. |

Also, when I plug in the wire that leads from the basement it takes five to ten seconds for the link to be negotiated and established by the two switches at each end. |

The extended negotiation time indicates a wiring issue. Did you put new ends on the cable? I would put RJ45 Jacks on each end so you can keep the twists tight and close, then just use a patch cable at each end to connect to the switch. Check for damage to the existing cable, especially near the connector. |

OK, I replaced the connectors on both ends of the cable. Before I only replaced it on one end of the cable. I looked at the connector that I had before on it which was a pre-made molded connector and I just didn't like the way that it had too much untwisted wire in the connector. So I remade the connector. I have those special EZ-RJ45 connectors, the ones that you can shove the wire through to the other side of the connector, crimp down, and snip off the rest of the wire on the other side. I know, that's cheating. But it works great. So I spread out the wires according to the T-568B specifications and shoved the wires into the connector as far in as it would allow me to. I checked the wire mapping on the other end of the connector and crimped down. I then tested the wire with my tester and it passed. So I then proceeded to connect it to the switch. The link came up in about a second, maybe even less then a second. That's far better than the five or ten seconds that it took for the link to come up before. -- Tom |
