Network issue

[GMW]

So I have a home server with a quad gigabit network card. And it is hooked to a gigabit switch. I've tested it from a rig with a gigabit port and got 1gb/s copy speeds. Today I installed another quad gigabit card into my gaming rig hoping to get 4gb/s copy speeds. But I'm only getting 400mb/s.

I've checked drivers, I've checked anything in bios. Nothing is adding up to why I'm not getting 4gb/s. And the switch I have lights up green for 1000mb/s and yellow for 100mb/s. So it isnt getting a gigabit connection. Please help. 

Card is: Intel Gigabit ET Quad Port server adapter. 

I have same card in my server running windows 10. And no issues. Only different is my server is a amd threadripper and this is an intel.

How is it setup? Are you using smb multichannel? Is lacp involved?

 

Do all the ports have different ips?

Without anything configured, it will be like you have 4 independent 1 gbps network cards.  The programs in your computer will use a single connection on a single network card to transfer a file. 

 

Like the guy above me says (too long name)  you need to use technologies to combine the ports into a single 4 gbps link. 

Without anything fancy, you could get 4 gbps by giving each network card a unique local IP and then you'd have to configure the other computer to request files through each network card you have. 

 

For example, a basic simple test would be to set up a FTP server to listen on all four IPs you assigned to the network cards and then open 4 separate ftp clients on the other computer and have each ftp client connect to a different IP and transfer a file.  You'll get 4 simultaneous transfers (or multiple simultaneous transfers through each network card, if you configured each ftp client to use multiple connections)

Each port has it's own ip address on the lan. And it does use all 4 at the same time when transfering files from my server. But they are stuck at 100mb/s each when the card is designed for 1gb/s each. And the intel pro software wont let me configure it. Like the drivers are not installed even though they are.

Where are you seeing this 100mb/s? We need to be sure that you are not seeing MBps rather than Mbps.

So the ports are negotiating at 100Mbps when you connect them rather than 1000Mbps? If so have you tried swapping the cables with the other one that you know works, then if that doesn't change the situation shutdown the server and workstation and put the NIC from the workstation in to the server that is known to work and see what the switch ports negotiate at then.

So funny story. The cables I am using to connect my gaming rig to the switch are only rated for 100mb/s but they are cat6. Switched cables and am getting 1000mb/s total now. Is there a way to get 1000mb/s for each port?

They are not CAT6 then or the cable is damaged. Cat5e and above should have NO issue pulling gigabit. You cant have Cat6 rated at 100mbps because the whole thing is standardized. And if a cable manufacture is not adhering to the standard then you shouldn't be buying their products.

What are the ports rated for? If you have lets say an 8 port gigabit switch then all 8 ports should be able to communicate at Gigabit speeds.
