• Connecting a desktop PC to a local area network (LAN)
• Replacing a failed or outdated onboard Ethernet port
• Stable wired connections for office workstations and point-of-sale systems
• Network access for systems where Wi‑Fi is restricted or unavailable

Key specifications

• Maximum data transfer rate: 100 Mbit/s
• Connectivity type: wired Ethernet
• Interface: standard Ethernet port (RJ‑45)
• Form factor: internal expansion card for desktop systems
• Compatibility: desktop PCs and systems with compatible expansion slot

How to use

Install the card into a compatible internal expansion slot following your computer manufacturer’s safety guidelines: power down the system, open the case, secure the card in the appropriate slot, and reassemble the chassis. Connect an Ethernet cable between the card’s Ethernet port and a network device such as a router or switch. After powering on, allow the operating system to detect and, if necessary, install drivers for the network adapter. Verify network settings in the operating system to ensure proper IP configuration and connectivity.

Recommendations

For reliable performance, use quality shielded Ethernet cabling and connect to network equipment configured for 100 Mbit/s operation or auto-negotiation. Ensure the system BIOS and operating system are up to date and install manufacturer-provided drivers if automatic detection does not provide full functionality. If used in business environments, verify network security settings and physical access to the device.
