Business Laptop Wi-Fi System: heat-sensitive network hardware. The adapter becomes unstable as its controller warms.

The distinguishing clue

Traffic starts normally and disconnects after sustained transfer.

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: Monitor temperature and reproduce with controlled network load. If confirmed: Replace the heat-sensitive module or correct nearby cooling.

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

Related cause to rule out

When the device disappears across operating systems or fails a known-good swap, also consider Business Laptop Wi-Fi System: wireless or network module failure before choosing a repair.

Checks after the work

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