Discussion about Ethernet issues
You're trying to change your Ethernet adapter settings but aren't getting a stable connection. With a CAT6 cable and an IPS port supporting 1Gbps, the issue might be related to driver compatibility or network configuration. Check if your adapter drivers are up to date and ensure the switch supports the higher speed without conflicts.
Check the laptop or computer motherboard along with the router you're using. Make sure neither supports gigabit; adjusting it won't help. Updated November 30, 2021 by The_russian
Don't recall the motherboard model, but I remember it supports 1GBPS because that was the reason you chose it. You also have a Netgear Mesh Wifi 6 setup that handles up to 1.8GBPS speeds.
That rating refers to WiFi performance and isn't related to Ethernet. The actual number you see in practice is rarely close to what it claims. Even if the router has Gigabit ports, it doesn’t automatically mean it supports true Gigabit internet. The internal hardware must be capable of handling NAT at those speeds. Many routers fall short in this regard. Cable connections can become damaged. I’ll try a different cable. You need all eight wires for speeds above Gigabit.
Your device needs a direct link to the main router to reach 1Gbps. Using a satellite router without Ethernet connection to the core will prevent achieving that speed. Core router refers to the modem-connected device, while satellite router is one of the mesh access points. Even with Cat 6 cable, breaks or termination problems can block 1Gbps performance. Consider testing another cable if needed.
Next steps should verify the modem supports a gigabit connection. As suggested, test with another cable—damage might allow 100Mbps but not higher speeds.
The modem isn't important. The computer is connected to a separate router. The connection speed is determined through that.
