V.TOP USB 3.0 to Gigabit Ethernet NIC 10/100/1000 Mbps Network Adapter with 2 RJ45 Lan Ports Supports Windows and MacOS

-lets you add two Gigabit Ethernet ports to your laptop or UltrabookTM computer through a single USB 3.0 port, and features an integrated USB 3.0 pass-through port that keeps your USB port available for use with external storage or other peripherals. Each RJ45 port supports 10/100/1000 Mbps Ethernet and is fully compatible with IEEE 802.3i/u/ab standards.

This 2-port USB LAN adapter is a versatile solution for connecting to two separate physical networks simultaneously, leveraging the 5Gbps speed of USB 3.0 to provide dedicated gigabit bandwidth to each port. The dual USB NIC is also ideal for providing dedicated physical network interfaces to virtual machine configurations. Great for IT administrators that require dual-homed or multi-homed host systems. The USB 3.0 NIC supports IPv4/IPv6 packet Checksum Offload Engine (COE) and TCP large send offload to reduce the load on your CPU, as well as Jumbo Frames, full-duplex operation with 802.3x flow control, and VLAN tagging for an efficient and full-featured USB network adapter.
