Microconnect MC-M.2-B+M-8111H-Q - Network Interface Card

The MICROCONNECT MC-M.2-B+M-8111H-Q is a PCIe M.2 B+M quad-port RJ45 network card for desktop PCs. It connects via an M.2 B+M key slot using the PCI Express interface. Designed exclusively for wired networking, the card omits wireless functionality to focus on physical routing. It supports data transfer rates of up to 1000 Mbit/s, making it suitable for embedded systems, firewalls, and custom network appliances that require reliable wired connectivity.

Four independent Realtek RTL8111H controllers manage data streams to ensure stable performance across all connections. The card is compatible with Windows 7 through 11, as well as FreeBSD and Linux kernels 3.x and later. Weighing 120 grams, it installs into small-form-factor chassis without straining the motherboard slot.

• Four Gigabit Ethernet (RJ45) ports for multi-network routing
• VLAN tagging for traffic isolation and management
• Wake-on-LAN for remote system activation
• Compliant with IEEE 802.3, 802.3u, and 802.3ab standards
• Backward-compatible with 10 and 100 Mbit/s data rates for legacy equipment
