The i226-V network card used in the Intel 700 series motherboard is defective

The i226-V code-named “Foxville” is Intel’s latest 2.5Gbps Ethernet network chip. It debuted on the Intel 700 series chipset, replacing the past i225-V, which is a consumer product. Recently, many users have reported that i226-V disconnects frequently, and the duration may last for a few seconds, so some users may not notice it.

According to TechPowerup, since mid-December, many users of Intel 700-series motherboards have reported random dropped calls to its support community, Microsoft, Asus, and Reddit. The short-lived disconnection may not necessarily be noticed by users, but for applications that require a continuous network connection, including online gaming, video conferencing, VPN, and remote desktop control, the impact is obvious. If the user opens the Windows Event Viewer, learn about these exceptions through “Windows Logs” and “System”, or search for “e2fnexpress” event 27 or event 32 to determine whether there is a problem.

At present, using Intel’s latest network card driver or motherboard firmware cannot solve this problem. Even forcing a 1Gbps connection may not completely eliminate the problem. If the motherboard used is configured with dual network cards, and the other Ethernet card is a third-party chip such as Realtek or Marvell, it is recommended to replace the connected interface. Of course, you can also choose to install a PCIe network card or use a Wi-Fi wireless network connection.

In fact, the i225-V in the past has been plagued by various problems. The connection is unstable under the 2.5Gbps network, and data loss or performance degradation may occur. However, it can be solved by forcing the connection at 1Gbps. The i226-V problem seems to be more troublesome this time, and there is no solution available for the time being.
