Problem with connectivity
Problem with connectivity
I have a home server equipped with a quad gigabit network card connected to a gigabit switch. I've verified speeds from a machine with a gigabit port reaching 1 GB/s. Recently, I added another quad gigabit card to my gaming rig aiming for 4 GB/s speeds. However, I'm only seeing about 400 MB/s. I've checked the drivers and BIOS settings, but nothing seems to explain the discrepancy. The switch displays green for 1 GB/s and yellow for 100 MB/s, indicating it's not receiving a true gigabit connection. My server runs Windows 10 and uses an Intel Gigabit ET Quad Port adapter, while the same card works fine on my AMD Threadripper. Please help me understand this issue.
What configuration is in place? Are you employing SMB multichannel? Is LACP included? Do each ports have unique IP addresses?
Without any setup, it behaves as if you possess four separate 1 gbps network cards. Your computer’s applications will rely on a single connection through one card to move files. As the person above mentioned (long name), you must employ methods to merge the ports into one 4 gbps connection. Without advanced tools, you can achieve 4 gbps by assigning each card a distinct local IP address and then setting the other machine to request files via every card. For instance, you could start an FTP server that listens on all four IPs you’ve given to the cards, and then launch four separate FTP clients on the other machine, each connecting to a different IP to download a file. This would allow four transfers happening at once (or multiple transfers through each card if configured properly).
Each port has its own IP address on the LAN. They all use all four simultaneously during file transfers from my server. However, they reach 100MB/s each when the card is set for 1GB/s each. The Intel Pro software refuses to allow configuration, even though the drivers are present.
You're asking about the speed you're observing—100mb/s? We should confirm whether you're actually seeing 100Mbps or 1Gbps. The ports are likely negotiating at 100Mbps when you connect, not 1Gbps. Have you tried using the other cable that you know works? If it doesn't improve things, shut down both the server and workstation and swap the NIC from the working workstation into the known-working server to check what ports negotiate at then.
They don't seem to be CAT6, so the cable might be damaged. Cat5e and higher should work fine for gigabit speeds. You can't expect a Cat6 rated at 100mbps because the standards are set. If a manufacturer isn't following the rules, you shouldn't purchase their products. What do the ports support? For example, with an 8-port gigabit switch, each port should handle gigabit communication.
