Optimal Ethernet configuration for 1GB internet speed
Optimal Ethernet configuration for 1GB internet speed
Auto Negotiation isn't necessarily the optimal choice for your setup. Your configuration uses a high-speed Intel card with a dedicated port, but the router's port is limited to 2.5GB. This could restrict bandwidth if you need more than that. Consider checking your internet speed limits and whether auto-negotiation might actually reduce performance in your case.
Essentially, auto negotiation should stay on unless you have specific needs. Changing it manually is mainly for old systems, troubleshooting, or when using outdated hardware that doesn’t handle speed talks well. Your router only has one 2.5G port and the others are gigabit, so connecting a modem to the 2.5G WAN and a computer to another port will only result in 1G speeds. If you’re having connection problems, try a different cable. Be cautious with Amazon purchases—many low-quality cables exist, especially for Cat 7. Even decent CAT 5e can support 2.5G Ethernet, so don’t rush into expensive cabling unless necessary. I’m using a Cat 5e patch cable from a 2002 spool for my proxmox/NAS setup and it works fine at 2.5G.
Agreed on all sides. Unless you're aiming to configure a very old NIC that only functions at 10/half, keep everything on Auto and allow devices to handle link speed and duplex. Most gear from the past 25 years should work out of the box.
