According to a report from
TechPowerUp, Intel's latest I226-V 2.5GbE Ethernet controller, which debuted on 700-series motherboards, may have a design flaw. User reports from the
Intel,
Microsoft,
Asus, and
Reddit (opens in new tab) communities allege that the I226-V controller causes frequent connection drops at random times, suggesting a potential design flaw.
The I226-V controller, codenamed Foxville, is the successor to the I225-V controller launched in 2019. Unfortunately, the I225-V wasn't perfect and was plagued by many network connection problems that led to connectivity loss and performance deterioration. Since the issues could only be fixed at the hardware level, Intel eventually released the I225-V2 controller. Sadly, motherboards manufactured before the new revision continue to suffer from the issues, leading to workarounds such as gimping the controller to 1GbE mode instead of 2.5GbE.

Raptor Lake processors leverage the I226-V Ethernet controller. Luckily, the connection drops are brief; you probably wouldn't perceive them in daily usage. However, you'd notice the drops in other workloads, such as downloading a big file, online gaming, or in a video call via Zoom. It's easy to see whether connection drops are occurring on your system if you look inside Windows Event Viewer under the "Windows Logs" section and, subsequently, "System." In addition, TechPowerUp recommends searching for "e2fnexpress" and scouring for Event 27 or Event 32 errors.
Unfortunately, neither the latest Ethernet drivers from Intel nor the newest firmware for the motherboards solve the intermittent connection drops. TechPowerUp tried forcing the I226-V controller to operate at 1 Gbps, but that didn't completely solve the problem.
