Setting up a network to reach 1000mbps in a LAN involves optimizing hardware and configuration.
Hi there,
I'm trying to reach 1000mbps between my two computers. My configuration looks like this: Machine 1 is a Lenovo Y540 connected directly via Ethernet, which supports up to 1000mbps. Machine 2 is an older desktop with an i3 processor and has a built-in network card (2NIC) from the motherboard, but it only handles 100mbps max. I've got the Intel 9301CT Gigabit CT Adapter (link provided), which claims to support 1000mbps. The IPs are set up, but the Wi-Fi router uses DHCP. My network gear includes an AC750 wireless dual-band router and a TP-Link TL-SG108S 8-port gigabit switch, which supports 1000mbps. I followed the suggestions and connected everything to the switch, but when transferring files via SCP, speeds are around 12MB/s on both sides. The adapter seems capable of higher speeds, maybe over 20MB/s? Could you help me understand why it's not reaching that? Thanks, Bhargav
Windows might default to using the 100 mbps network card instead of the 1 gbps card. The simplest solution is to open the Control Panel, navigate to Network Connections, and turn off the 100 mbps card so only the 1 gbps remains active. Another option is to access Device Manager, disable the network card, or adjust the BIOS settings to remove the built-in network adapter. Ensure both gigabit cards are connected to the same switch and that all eight wires are correctly matched in the connectors on both ends. If you crafted the cables yourself, they should follow one of the two standard arrangements shown below.
