Set up a local network between PCs using Ethernet so devices can communicate directly.
I play Minecraft on an older PC linked via Wi-Fi to a newer PC connected through Ethernet. I have another Ethernet cable, but I’m avoiding Wi-Fi because it’s too short for reliable performance inside the room. Can I set up a direct connection between two PCs using only Ethernet? I understand it’s feasible, though I suspect it’s mainly useful for file sharing rather than streaming or gaming.
I believe you're referring to two NICs connected via a single cable between the two PCs. Install a network card in each computer (usually already built into the motherboard, so no extra hardware needed). Link them using a Cat 5/6/7 cable. Assign IP addresses on each device, such as 192.168.0.1 and 192.168.0.2, with a suitable subnet mask like 255.255.255.0. You're all set. Beyond latency, skipping a router should have little effect unless the network speed is below gigabit. In a local setup, latency is usually under 1 ms either way.
Each computer should have its own network card, connected via a single cable linking both devices. For older motherboards, the network functionality may be built-in.
You can connect both PCs using your Ethernet cable, but file sharing is the standard method. To set up Minecraft connections, follow the specific steps for each device as needed.
You don’t need any special steps. Because you’re not linked to a router with DHCP, devices won’t get IPs automatically. You must set each PC’s IP and netmask manually, ensuring they’re on the same network. For instance, assign 192.168.0.1 to one machine and 192.168.0.2 to another, using 255.255.255.0 as the mask for both. Launch the Minecraft server on one of these devices, confirm the Windows firewall allows it, then run the client on the other and connect using the server’s IP address.
