Overview

The StarTech.com PR22GI-NETWORK-CARD is a dual-port 2.5Gbps PCI Express 2.0 x2 network adapter powered by the Intel I225-V controller. It leverages existing Cat5e/Cat6 cabling to deliver 2.5× the bandwidth of standard Gigabit Ethernet, with NBASE-T (802.3bz) support for automatic speed negotiation across 2.5G/1G/100M/10M. This card is ideal for desktop users who need faster wired networking for NAS, file servers, or virtualization without upgrading their cable infrastructure.

Connectivity & Compatibility

The card fits into any PCIe x2, x4, x8, or x16 slot (PCIe 2.0 or later). Two independent RJ45 ports each have their own Intel I225-V controller, enabling link aggregation, failover, or separate network segments. It supports Windows, Windows Server, VMware, and Linux. A low-profile bracket is included for compact chassis. The card also features WoL (Wake-on-LAN), VLAN tagging, PXE boot, and 9K jumbo frames.

Product Info

Released around 2023, the PR22GI-NETWORK-CARD sits in the mid-to-high tier of consumer/prosumer network adapters. It offers dual 2.5G ports at a competitive price point compared to 10G solutions. StarTech.com backs it with a lifetime warranty and free technical support. The package includes the full-height bracket (pre-installed), low-profile bracket, and a quick-install guide.
