2.5Gbps 2230 NGFF A+E-Key adapter

The Vszerda UT-028-AE-NG adds a 2.5Gbps Ethernet port to desktops or laptops that have a 2230 NGFF A+E-Key slot. It uses a Realtek RTL8125B controller and auto-negotiates down to 1Gbps, 100Mbps or 10Mbps. The card supports PXE boot, IEEE 802.1Q VLAN tagging, IEEE 802.3x flow control and IEEE 802.1P priority encoding. A low-profile bracket is included for slim chassis.

Upgrade from 1Gbps onboard LAN

This card replaces a standard Gigabit connection when the motherboard only offers 1000Mbps and the user has a 2.5Gbps switch or router. The jump is worth it when transferring large files between local machines, streaming high-bitrate video or reducing latency in competitive gaming. It will not increase speed beyond the 2.5Gbps link or improve internet throughput above the ISP provisioned rate.

2.5Gbps over Cat5e at 100 metres

The adapter handles 2500Mbps full-duplex traffic over standard Cat5e or better UTP cable up to 100 metres. It runs out of headroom when the network infrastructure is limited to 1Gbps ports or when the cabling exceeds the 100-metre specification. It is not for systems lacking a 2230 NGFF A+E-Key slot, for B-Key or M-Key only slots, or for users needing fibre connectivity.

Questions about this item

Does the 2230 NGFF A+E-Key card fit a standard low-profile bracket?

Yes, it ships with a low-profile bracket that fits slim desktop cases and standard full-height slots.

What is the common mistake when inserting the card into the 2230 NGFF A+E-Key slot?

Users often confuse A+E-Key with B-Key or M-Key slots; this card only works in A+E-Key sockets.

Will the Realtek RTL8125B controller need a firmware update after installation?

No firmware update is required; the driver for Windows 10, Windows 11 or Linux handles all features.
