Disable legacy Plug and Play OS in BIOS if present. | | No link light, but driver installed | Cable fault or forced speed/duplex mismatch | Manually set adapter to 100 Mbps Full Duplex, not Auto-Negotiation. | | Driver fails to sign | SHA-1 deprecation in newer Windows 7 updates | Temporarily disable driver signing enforcement: Restart -> F8 -> "Disable Driver Signature Enforcement". | | Cannot find Hardware ID | Chipset drivers not installed first | Install Intel Chipset Software Installation Utility (INF update) for G31 before LAN driver. |

The G31 chipset doesn’t have integrated LAN. Zebronics used different LAN chips depending on production batch. Most common:

Note: Zebronics does not manufacture the chipset or LAN controller — they use off-the-shelf Realtek components. Thus, Realtek’s generic drivers work perfectly. zebronics g31 motherboard lan drivers for windows 7 64-bit

The primary challenge is that Zebronics, as a value-oriented original equipment manufacturer (OEM), did not produce a consistent bill of materials. At least three different LAN controllers have been observed on Zebronics G31 boards:

Conclusion: Before any driver installation, the user must physically inspect the motherboard or query the hardware ID via Windows Device Manager (under "Unknown Device" -> Properties -> Details -> Hardware Ids). The VEN (Vendor) code will reveal the manufacturer: 10EC for Realtek, 1969 for Atheros/Qualcomm, 1106 for VIA.
