| 1346651 | 2013-06-22 05:50:00 | Can someone tell me if cat5 works at 1,000 or is that just cat5e? I have some cables from the 1998 days from my PCMCIA Xircom/USR/3Com cards and they work at 1Gbps. But I have a newer cable that came with an ADSL2+ modem router - it would work at 1Gbps with the laptop but with the base unit (docking station) it only connects at 100Mbps. My other cabls incl those from 1998 connects fine at 1Gbps without/without the dock. | Nomad (952) | ||
| 1346652 | 2013-06-22 06:27:00 | Everything needs to be 1gb (the nics), for it to connect @ 1gb. So, if the dock is only 10/100 it will only connect @ 100 | Speedy Gonzales (78) | ||
| 1346653 | 2013-06-22 06:30:00 | As far as I know Cat5 can operate at 1Gbit/s, but not very well - you'd be better off going with Cat5e or Cat6. | pcuser42 (130) | ||
| 1346654 | 2013-06-22 07:20:00 | That is the thing. If i use a older cable from 1998 on the same laptop, same dock, same network switch i get 1Gbit, same if i undock. If i use a cable given to me by one of my ex isp i get 1Gbps but then when i dock i get 100. Laptop, dock and my 8 port switch is gigabit versions. I have just installed cat6 solid cables behind walls and wallplates. Every other cable even older does 1Gbps on laptop or with the dock. |

| 1346656 | 2013-06-22 08:14:00 | As far as I know Cat5 can operate at 1Gbit/s, but not very well - you'd be better off going with Cat5e or Cat6. Common misconception, CAT5 works just fine at 1Gb/s. On longer runs or if you have a lot of cabling close together, or a noisy environment with a lot of EM interference, then sure CAT5e and CAT6 work better. Gigabit ethernet was developed to work on CAT5, then the cabling was improved to help it perform better. However in a normal household situation where cable runs are typically < 20M and there are usually only a handful of them at most you'd have a hard time proving any difference. By design ethernet cables between equipment can go up to 100M, when you start getting close to that the cable type matters a lot more. All I can suggest to the OP is the dock must be limiting you somehow. If you put a cable that can only do 100M between hardware that can do Gb speeds it simply doesn't work because both ends detect each other as being capable of Gb and use that speed which then fails. If you put a 100M device in the circuit however, the other end typically detects the 100M signal and drops itself down to match and it works. In other words a cable won't force you to 100M only hardware will, a cable will just either work properly or not at whatever speeds the hardware negotiates. |

You need all 8 wires to get 1gb. CAT5 cables will do 1gbps but probably not for a very long distance. |

| 1346658 | 2013-06-22 09:09:00 | The cable in question - same width, looking at the plug it has 8 wires. I do have another cable that is thinner, 4 wires, came with yet another ISP, this one goes at 100Mbps without the dock. For that original cable (8 wires), I know it was 1Gbit without dock and 100Mbps with dock. I am now gonna connect it to the laptop alone and test a file copy. But just now it reported 100Mbps connection, I reinsert the cable and got back 1Gbps. Maybe lesser workmanship? For a 1GB single video file, Windows reported speeds avg of 70MB/sec. I tried another cable and got faster speeds average of 100MB/sec and then slowing to about 80MB near the end. Maybe with the dock if I reinsert the cable it would hit 1Gbps too ........ |

| 1346660 | 2013-06-25 02:34:00 | Wow, lot of misconceptions here! Cat 5 cable and connector is designed to operate at 100MHz. So technically you can only get 400Mbps when using all 4 pairs Cat 5e cable and connector is designed to operate at 150 MHz. So can reach 600Mbps when using all pairs Cat 6 cable and connector is designed to operate at 250MHz. So will operate at true 1Gbps Yes you can use old Cat5 cable on Gigabit port. The port will negotiate 1Gbps but can only operate at 400Mbps sustained error free throughput. |
