Morning all!

I need a little help with my newly installed gigabit network. I have 3 machines hooked up to a 5 port Netgear switch. I've got Cat5 installed from my old 100MBit installation and was hoping to get away without having to upgrade it. Currently only two machines on the LAN have gigabit capabilities, but neither of them light up green (indicating a Gb connection).

Has anyone got any ideas? I've read conflicting reports of whether Cat5 will support Gb connections...
 
Do you need special connectors for Cat5e or can I use the same as the ones used for my 100MBit LAN? I have some left over from the previous install.

No, you can use normal ethernet 8 pin connectors. I'm taking your making your own cable?

Are you sure you cable is cat5e or is it something else?

EDIT: Make sure your operating speed on the lan is set to 10/100/1000 in the settings for the nic. Sometimes this may be turned off and manually needed to be selected from my experience with some cards.

Correct

I was convinced it was Cat5 not Cat5e, but looking back at my order, it would appear to be 5e!

I had a look through the settings on my machine (I'm using the onboard Gbit connection of my Lanparty Ultra-d motherboard) and couldn't find anything that looked like it was disabling Gb operation. Having just googled for my motherboard I've realised that the other port (I'm currently using the marvel chipset one) also supports gigabit connections so I'll try using that port tonight and see if it makes a difference.

Cheers for the advice :)

Good point; It's been a long time since I posted on these boards :eek:

I looked through all the settings I could find, and nothing made any difference. I might try bringing the new switch closer and try some shorter patch cables... If anyone else has some more straws to clutch at, I'd love to hear them :(

Finally found the problem - it was the way I'd connected up the wires. I'd done this:

Code: 
= white / brown
= brown
= white / blue
= blue
= white/green
= green
= white/orange
= orange

...but I needed:


Code: 
= brown
= white / brown
= green
= white / blue
= blue
= white/green
= orange
= white/orange

...with the cable pointing out to the right on those ASCII diagrams. Changing that over fixed it right away! :D

Just re-compiling the kernel on my server with support for the gigabit card I've got now. Hopefully that'll work alright and I'll finally have the gigabit connection to the server I've been after!
