Intel’s 700-series motherboards for 12th & 13th Gen CPUs are rumored to feature a faulty I226-V Ethernet LAN controller. Reports from TechPowerUp, Intel, Microsoft, ASUS, and Reddit communities suggest random drops in connection, leading users and designers to wonder if the controller has a design flaw. Intel has yet to make an official statement.

The I225-V controller, the predecessor to the I226-V, was also found to have issues such as network connection drops and losses in performance. The spots were hardware-related, meaning the hardware would need replacement instead of updating the firmware. Intel released the I225-V2 controller to update the hardware and alleviate the issues.

The I226-V drops in connections do not last long and are quick to be solved, but they can be noticeable when gaming, large file downloads, and some conference calls. Users can look at the “Windows Logs” in the “Windows Event Viewer” and click on “System” to witness the connection drops in real-time.

Intel has not released any driver updates to fix the issue, and the workaround of lowering the connection to 1GbE has been unsuccessful in completely resolving the issue. Some motherboards have dual Ethernet controllers and can change to third-party controller options from Realtek and Marvell or use the Wi-Fi integration on the board. Less expensive motherboards will need to purchase a wireless adapter or a PCIe network adapter.
