I bought a Gb switch and have connected it to my Comp and my PS3, but it is only working at 100Mb/s. Comp and PS3 have Gb ports and I have traced the problem to the wiring. I have used CAT5e cabling and this seems to be the problem, but I thought that CAT5e would handle this bandwidth. Is there anyway I can get Gb bandwidth from CAT5e or do I have to strip out my cabling and put in CAT6?

Thanks

Hi,
Keep your LAN card speed and duplex settings in auto mode it should work out. CAT5e will support Gb speed.

Cabling could be an issue but not due to CAT5e which supports gigabit.

Was this cabling home done? Does it follow the correct pinouts?

Are you ready for where Microsoft wants you to go today?

Cabling was home done. If you hold the connector with the pins facing you then the order is

O/w, orange, w/g, blue, w/b, green, w/b, brown

This was the way I was shown, and it has works everytime (for 10/100 speeds anyway).

Thanks for your help

Just noticed that wasn't too clear. The middle pair should be

white/green, blue, white/blue, green, white/brown, brown

gig uses all eight wires.
That looks like 586B so you should be fine.

Try setting both the nic and switch port manually to gig. What happens?

Deathlyphil,

Curoius - Are you sure your ISP provisioned GB speed for your intenet? If they have not, you will never attain GB speed no matter what you do with the ethernet cable connector,

If the ISP is doing GB speed, who are they and how much does that cost? I doubt that his ISP gives GB speed, so he must just want GB speed for his LAN.

The significant problems we have cannot be solved at the same level of thinking with which we created them.

I have seen cat 5e that did fail on gig.

Could be autodetect function fails.

Use adapters software if present to set to gig. May have diag with the adapter to tell more. Usually higher end adapters have that.

I read it wrong and answer it wrong too. So get off my case you peanut.

How do I set the auto-detect options? I know it must be the cable because I tried swapping it for a CAT6 cable and it connected at one gigabit.

After pulling/terminating a bunch of cables (or a single) one should always test and certify the cable. I've pulled many miles of cables and terminated and tested them all. We use Cat5e extensively where I work and it all carries 1000 Mbps without any trouble. On cables that have been tested/certified the only time I've ever seen them unable to carry 1000 Mbps was if there was an issue with the interface of whatever device was plugged into the cable. It's never been the cable itself.

Did you have your cable(s) tested and certified before trying to use it?

If you manually set your NIC for 1000 Mbps full duplex, keep in mind, whatever is at the other end has to also be manually set to the same. To set your NIC manually to 1000/full you will want to right click on My Network Places and select Properties. Then, right click on the NIC and select Properties again. In the property window click on the button labelled "Configure" near the top. In the window that opens up, click on the "Advanced" button. Then highlight "Link Speed & Duplex" and use the pulldown ("Value") to the right to set speed/duplex.

Since you say it works with Cat6, I suggest either the cable itself is improperly wired or has issues of some sort which testing/certifying would reveal. If you don't have a tester available, you may want to get yourself a new Cat5e cable and try it out and see if the cable is the issue.

To be exact. I have seen premade cables that were claimed to be 5e that failed gig.

I read it wrong and answer it wrong too. So get off my case you peanut.

That's kind of what I thought you were talking about. The problem with mass manufacturing of anything is that you can't test everything before shipping for sale. So if you're going to have an issue with a cable, it'll likely be a premade (and untested) cable like that.

It's annoying and frustrating and that's why all the cables in my home are one's I've made and tested/certified myself.

Ok, see what you think of this. I saw that someone mentioned the two types of wiring, 586A and 586B. I've wired everything up as per 586B because that was the way I was shown and I haven't had any problems with it before.

Looking at the box for the CAT5e cable, it says on it "568A", so I decided to rewire a cable in that way and behold: it works connects at 1Gb/s. Can anyone explain why this would make any difference at all?

It wouldn't make any difference, if it worked there must have been a bad end or not a good connection on all of the pins. NICs don't care if it's 568A or B or any other standard. They don't know the difference between orange and green. To sum up you fixed the faulty cable, if you would have left the pinout the same it would have worked too.

The significant problems we have cannot be solved at the same level of thinking with which we created them.

What buckethead said!

Your cable mustn't have been wired correctly at the outset. It has nothing to do with using the A or B standard. Both are essentially the same except for the green/orange pairs are reversed. It's handy to know that a crossover cable is wired A at one end and B on the other.

Just one more note on this since I have installed many miles of this cable myself, about 90% of the time cable failure is due to faulty connections in the jacks or plugs due mostly to improper punch down.

Always make sure to get certified cat5e devices and always leave a little slack so It can be re-puched down if necessary.
