Speed limit set to 100mb/s following motherboard upgrade
Hi, Your ISP recently added a fiber connection offering up to 1gb/s download speeds. After setting up the new router and connecting via fiber, you achieved around 800mb/s download and 200mb/s upload. Two days ago, you swapped your motherboard for an Asus ROG STRIX Z370-H GAMING model (with OC CPU and RAM). It booted fine without formatting, just needed driver installation. From a software standpoint, your PC remained the same except for the hardware change. However, your LAN speed is now limited to 100mb/s, and you’re unable to adjust it. If anyone can assist in unlocking full 1gb speeds on your motherboard, that would be greatly appreciated.
Verify the connection rate in the control interface. Likely it operates at 100 Mbps, so you may need to increase it to gigabit.
Open the "Local Area Connection" in the Control Panel, click on it, go to Properties, then adjust the settings. Look for the "Speed & Duplex" option and choose either Auto negotiate or set it to 1.0Gbps. The display will show the current configuration.
verify the correct drivers are in use, experiment with another port on your router, test with a different cable. attempt to force it to 1Gbps; a faulty cable would likely cause the network to drop if you set its speed and duplex incorrectly, as the cable may not handle that speed.
The issue started after updating my computer specifications. I installed the proper drivers and even reinstalled them. The connection cable seems fine because I used it before the changes and it functioned well. Additionally, when I try to set the speed to 1Gbps, the tray icon shows a disconnected cable warning and there’s no internet access. Could you suggest other possibilities?
forcing to 1gbps causing a disconnect brings up a few points. First, neither of these options can reach 1gbps; possibly the router settings are set to auto-negotiate at 100mbps instead. Second, the drivers installed for the new network interface might be incorrect—Intel I219-V NIC appears on the motherboard info, so uninstall the network adapter in Device Manager and reinstall the drivers you downloaded. Be sure to remove any other network software you may have installed. It could be using a partially compatible Intel driver that doesn’t fully support your chipset. I’d also suggest testing with a different cable or port on the router just to eliminate a possible hardware issue.
I removed the device from Device Manager and reinstalled it using the 1219-V NIC intel driver, but the problem persisted. It seems the router doesn’t have any settings to fix this issue, as other computers in the house are also getting a 1GB speed connection. I switched to a different port and cable, though results were less effective. I’ve been working on this for hours and it’s becoming increasingly frustrating.
That's unusual, isn't it? Could the bios contain any information that might affect this? As long as the driver is correct and the cable/port didn’t change, I’m still puzzled. There’s no explanation for why it should be negotiating at 100Mbps unless the port is faulty and can only handle half the pairs.
After purchasing a new Ethernet cable out of frustration, the issue was resolved. It turns out both cables I tried were defective—both were CAT 5, which I didn’t realize I had on hand. The one I received is CAT 6 and functions perfectly. Thank you for your assistance and support; it made a big difference.
