Your local network performance isn't meeting expectations.
You just received your new motherboard, a Z390 gaming pro carbon AC. You hoped for speeds over 10 MB/s, but it’s still stuck at 10 MB/s on Ethernet. The manual says it’s a gigabit LAN port, and you have fiber internet with gigabit speeds. Your Xbox downloads at 100 MB/s, while your PC connects to the network at 883 Mbps or 83 MB/s. When you plug in the WiFi adapter for the motherboard, it works much faster—checking ‘network and sharing’ shows a speed of 83 MB/s. Your Ethernet cable is giving 10 MB/s, which is lower than what your PC sees. It seems the issue might be with the Ethernet cable or connection quality. You’ve tried switching cords and even moved devices around, but the PC still can’t match the router’s full capacity. Could it be the cable isn’t sufficient? If so, how can you test it further?
Check if your PC is linked directly to the router or via a switch. Use a different cable connected straight to the router. If it only gets 100Mbps, that’s why it can’t reach 10MBps. Also, try configuring speed and duplex as 1Gbps Full Duplex instead of auto-negotiation to see if the connection works.
The setup passes through a few wall ports, and the Xbox cable works fine. To adjust the speed and duplex settings, you can change them in the device settings or via the manufacturer's app.
There could be a faulty link on one of those wall ports. I've experienced problems before with gigabit connections dropping and resetting it usually resolves most issues. Start by using a cable directly connected to the router first, then check the port through which the Xbox connects. If that works better, the problem likely lies in the connection between the PC and the router. Without knowing the exact cabling layout, it's difficult to pinpoint the issue. Replacing all cables between the PC and router should be the initial troubleshooting step, not just the one linking the PC to the wall port. Network settings > Right click > Properties > Configure > Advanced > Link Speed/Speed & Duplex.
ok so i dont have link speed in that list for some reason. I also just checked the office computer and it goes straight to the router and it says it has a 1 gbps speed. so it seems all signs would point to a bad wire or connection, but is there any reason why link speed inst showing up in those setting?
I checked the speed and duplex settings, chose 1G, and now it shows Ethernet not connected. Still, I updated all the drivers after completing the motherboard installation.
It seems there might be an issue with the connection or a device restricting bandwidth. I'd begin by checking the cables first, testing if switching them improves the link. For 1G testing, if it works, you've likely fixed the problem. If not, try re-terminating the wall ports—unless another port is available. If needed, replace the cables or connect the Xbox to a switch and then your PC.
Often the problem lies with low-cost or inferior ports. It usually needed several restarts to make a link function with budget euro boards. Trying to connect straight from the router using a cable is the initial check to ensure the router or computer isn’t the cause. I assumed it would work, but it’s still good to verify so you don’t waste time and effort on faulty hardware.
