Intel Ethernet Controller I225-V
Intel identifies I225-V as a single-port controller in the I225 series, and the I225/I226 product brief describes operation through 2.5 Gbps. Host boards and controller revisions can have different driver or NVM guidance. Check the cable, switch, settings, driver, and exact host advisories rather than prescribing a generic firmware alignment or Energy Efficient Ethernet change.

This coverage label describes releases discussed by this publication, not certified compatibility. Confirm the exact device or PC model, hardware revision, current Windows release, and current package requirements on the publisher source before making a change. Windows 10 Home and Pro reached end of support on October 14, 2025. Extended security updates and other editions have separate lifecycle terms; a driver listing does not extend Windows support.

Device Driver Guide does not host driver files or bundle an updater. This page documents the Intel Ethernet Controller I225-Vfamily; its citations are selected from the package-source policy recorded for this family.
Device Driver Guide hosts no executables or updater tools. External citations are limited to official publisher documentation pages and are labeled before you leave this site.

The family record names Exact board or Intel package that lists the controller revision as the package source. Use Varies by exact controller, hardware revision, system or board package, and Windows release; verify the official support page only as reference coverage, then check the current publisher requirements for the exact model, hardware revision, Windows release, and PC configuration. A family name alone does not establish compatibility.
Shared identification, preparation, installation, verification, and rollback procedures are maintained on the full ethernet & lan guide, rather than repeated on every family page. The citations below follow this family’s declared vendor, system-update, PC-maker, or motherboard-maker source policy.
Official sources and citations
These links serve two different purposes. A manufacturer support selector helps you find an exact model, but does not prove that a package or feature exists for every product in a family. Claim-specific documents explain the cited technology, requirement, lifecycle, or bounded package example. In either case, check the publisher domain, exact model and hardware revision, operating-system release, supported-products list, and package notes before making a change.

Device Driver Guide is an independent reference, not a repair or technical-support service. It does not host or mirror installers and receives no payment for these links. A named-model package example applies only to the systems and operating systems on that publisher page; it is not a recommendation to install the package across a family.
