Hey there, I noticed your new PC is only reaching 100 Mbps on Ethernet, even though the cable supports up to 600 Mbps elsewhere. You tried tweaking settings in Device Manager and changed the negotiation mode, but the port still shows the limit. It seems like the issue might be with the driver or network configuration. Have you checked if your network adapter is properly installed and recognized? Also, consider testing with a different cable or another device to rule out hardware problems. If the problem persists, reaching out to your ISP or contacting support might help.

Do you connect to a 100mbps device? This speed is quite typical for many applications.

The opposite end of the cable connects to a different port, and it can handle gigabit speeds or just high-speed Ethernet depending on the device.

Start by reverting any adjustments you made to Duplex to Autonegotiate. In a properly configured setup with Gigabit devices, performance should default to full speed. The issue probably lies either with a non-Gigabit device in the line or a faulty cable.

The cable connects to a router that is powered by a fiber connection. The router can handle fiber because the same cable used for my laptop delivers 600mbps, whereas the new computer achieves higher speeds.

I thought that was the right conclusion because all the cables, router, and other devices function properly on different machines. It seems the issue might be with the new PC itself. I’m checking if there’s a specific setting or driver I need to install.

Check the model of your network interface card and look for available drivers. It seems Windows isn’t recognizing or installing the correct one automatically.

The router's model should match your gigabit NIC compatibility. If you have a gigabit LAN port, the router should work without problems.

I completely removed the driver, then downloaded the same version from the site on another device and installed it via a flash drive. It worked, apparently. Thanks for all the advice and quick replies! It looks like Windows is just behaving normally now.
