Explanation

Troubleshooting should always start with the simplest, least invasive check. Many laptops have a physical wireless on/off switch (hardware toggle) or a function key combination (e.g., Fn+F2) that enables or disables the wireless adapter. It is very common for this switch to be inadvertently toggled during a motherboard replacement. Checking the switch first costs no time and requires no disassembly. Only if the switch is confirmed to be in the 'on' position should the technician move to more involved steps like checking antenna connections (B), reinstalling drivers (C), or concluding the motherboard is defective (D). Jumping to disassembly or hardware replacement before checking the switch violates the principle of working from simple to complex.
