Intel PRO/1000 MT PCI adapter

The Intel PWLA8390MT is a 32-bit PCI 2.2 network card built around the Intel 82540EM Gigabit Controller. It delivers 10, 100 or 1000Mbps Ethernet through a single RJ45 port and supports Wake On LAN, PXE boot and ACPI power management.

Desktop owners with legacy PCI slots

This card suits systems that still offer a 32-bit PCI slot and need a reliable wired gigabit link. Builders working with PCI Express only motherboards or anyone requiring multiple ports, fibre connectivity or Wi-Fi should look elsewhere.

Gigabit throughput on Category-5 cabling

The adapter meets IEEE 802.3ab and runs at full line rate on standard Category-5 cable up to 1000Mbps. Performance drops to 100Mbps or 10Mbps when connected to slower switches, and the single port limits aggregate bandwidth to one gigabit link.

Questions about this item

Does my motherboard need a 32-bit PCI 2.2 slot for the PWLA8390MT?

Yes, the card installs in a 32-bit PCI 2.2 slot and will not work in PCIe slots.

Will the Intel 82540EM controller negotiate 100 Mbps with my older Fast Ethernet switch?

Yes, it supports 10BASE-T, 100BASE-TX and 1000BASE-T so it will link at 100 Mbps with that switch.

How do I confirm the PWLA8390MT is operating at 1000 Mbps after installing the driver?

Check the link speed in the adapter properties or OS network status; it should show 1 Gbps when connected to a gigabit port with Category-5 cabling.
