The NETGEAR FA310TX is an auto-sensing, 100BASE-TX Fast Ethernet PCI adapter designed to support multimedia power-applications. The NETGEAR adapter is like 2 products in 1 while it supports the 100BASE-TX 100 Mbps high-speed standard, it also runs in the pervasive 10BASE-T 10 Mbps mode. Install the adapter once, and it will operate with either 10 Mbps 10BASE-T or 100 Mbps 100BASE-TX hubs or switches. Single network connection works at either speed - the FA310TX can be introduced in a 10 Mbps environment and later upgraded to 100 Mbps with no changes to the desktop. A graphical interface guides the user through the installation of software drivers and support files for all popular network operating systems.
