Intel® Ethernet Controller I225-V Unable to Reach More than 200Mbps


Windows® 10, 64-bit*


Troubleshooting recommendations or suggestions for I225-V not reaching more than 200Mbps

  • Intel I225-V ethernet controller on Asus ROG Strix B550-F Gaming cannot reach more than 200Mbps.
  • Ran several speedtests and the speed never crossed 200Mpbs.
  • Tested the connection on different computer and Ubuntu* live boot on the same system where the issue occurs and is able to reach more than 200Mbps.
  • Double-check if the established connection speed in the settings can reach 1Gbps. To confirm this, go to Network and Internet Settings. View your Network Properties and scroll down to Link speed (Receive/Transmit).
  • Ensure that the Model/Access-point/Switch or device on the other side comes with full Gigabit support.
  • Test the speed on another system to ensure that it is not an issue regarding cable, operating system, Internet, and hardware itself.
  • Update the driver to latest version. If Intel® Ethernet Controller is embedded on Original Equipment Manufacturer (OEM) system, it's best to check with the manufacturer as the software drivers linked from Intel page are generic versions, and can be used for general purposes. To avoid any potential installation incompatibilities on OEM system, Intel recommends checking with the OEM and use the software provided via system manufacturer.
  • Ensure that Speed & Duplex settings on Advanced tab property of the Intel Ethernet Controller is set to Auto Negotiation.
  • Try reinstalling the Operating system to fix the issue.
  • If issue still occurs, contact System Manufacturer for further assistance.
