Business Laptop Wi-Fi System: wireless or network module failure. The adapter electronics no longer communicate reliably with the computer.

The distinguishing clue

The device disappears across operating systems or fails a known-good swap.

Checks before an assessment

Record the office network, dock state and authentication message. Compare only authorised networks and leave managed security settings in place.

Stop point: Preserve managed-network and encryption settings during diagnosis.

Workshop confirmation and repair

Device-level check: Compare another approved network, direct and docked use, power state and authentication behaviour.

Targeted check: Check module power, bus detection and approved compatibility. If confirmed: Replace the confirmed module and retest its antennas and drivers.

Repair boundary: Repair the confirmed configuration, antenna, module or driver path without weakening security.

Related cause to rule out

When the adapter shows an error or vanishes after Windows loads, also consider Business Laptop Wi-Fi System: network driver corruption before choosing a repair.

Checks after the work

After repair or replacement, check office network, hotspot, meetings traffic, dock transition and sleep.
