No driver is required on Windows10; drivers for other operating systems can be downloaded from the Realtek official website. Dual-port expansion: Installs into a PCI Express x1 slot to add an extra RJ45 port to your desktop, ideal for systems with limited network ports or when a network port has failed. Slot and bracket support: The card fits PCI Express x1, x4, x8 or x16 sockets. An additional 8cm low-profile bracket is included for compact HTPC or small form-factor cases. NOTE: Only work with PCI-E slot, Not for PCI Slot. Installation options: Package contains both low-profile and full-height brackets so you can choose the bracket that matches your chassis.
