"The JMC25x/JMC26x is a single-chip PCI-E..."The JMC25x/JMC26x is a single-chip PCI-Express Gigabit Ethernet Controller. The Ethernet function is compliant to IEEE 802.3 Media Access Controller, and IEEE 802.3u 1000BASE-T/100BASE-TX/ 10BASE-T. The MAC supports IPV4, IPV6, TCP, UDP checksum, segmentation task-offload, priority encoding and IEEE802.1Q VLAN features. It also supports Receive Side Scaling (RSS) to balance the loading for multiple CPUs. The Ethernet function supports remote wakeup (including AMD Magic Packet? and Microsoft? Wake-up frame) in both ACPI and APM (Advanced Power Management).

Before installing version 0.0.33.3 of JMicron JMC25x/JMC26x Ethernet Controller Driver for Windows make sure this is the latest version available and that it works with your current operating system and device model. If the driver contains release notes ("readme" files) proceed with reading them first. Second recommended step is creating a restore point to help you later on in case you install the wrong device driver. Note that some drivers will work instantly after installing them, but others will require a system restart in order to function properly.
As an alternative, you can simplify the process of installing the latest versions for your drivers by using a program to scan all your drivers and compare them with the latest available versions from the manufacturers. We recommend Driver Scanner from Uniblue for such a task. Download it and run a free driver scan here.
