Explanation
A USB to RJ-45 (Ethernet) dongle is an external network adapter that plugs into a USB port and provides a working wired Ethernet connection, bypassing the faulty internal NIC entirely. This is the fastest and least invasive solution. Enabling Bluetooth (B) is a short-range wireless technology not suitable for wired network connectivity. NIC teaming (C) combines multiple NICs for redundancy or throughput but requires multiple working NICs and is not a quick fix. Replacing the motherboard (D) is an extreme, expensive, and time-consuming repair that should only be considered as a last resort.
