According to research conducted by the team at TechPowerUp, the issue is attributed to the I226-V controller when running in its default 2.5 GbE state. The short.
Why it matters: A suspected design flaw in Intel’s I226-V Ethernet controller is causing connectivity interruptions on some Intel z700-series motherboards. The break, which has been reported on multiple forums since late last year, typically lasts several seconds and occurs without warning. The issue is specific to Intel’s 2.5GbE controller on the impacted boards and does not affect Realtek, Marvell, or other types of onboard controllers.
According to research conducted by the team at TechPowerUp, the issue is attributed to the I226-V controller when running in its default 2.5 GbE state. The short duration connectivity drops occur at random and may not be noticeable by some users depending on their specific activity level. It does, however, create a noticeable impact to any users engaged in tasks or activities requiring a steady, reliable connection such as gaming, streaming, or using any PC-based communication tools.
