Laptop Wi-Fi System: firmware or regulatory configuration fault. The adapter operates with the wrong capability, region or approved band settings.

The distinguishing clue

Specific channels or modes are unavailable despite correct hardware.

Checks before an assessment

Compare another authorised network and record whether the adapter disappears or merely loses connection. Keep the router, distance and task unchanged when comparing results.

Stop point: Antenna plugs are delicate and the battery should be isolated before handling them.

Workshop confirmation and repair

Device-level check: Compare firmware detection, another network and sustained traffic before replacing hardware.

Targeted check: Check approved firmware, region and access-point configuration. If confirmed: Restore supported settings without bypassing regulatory controls.

Repair boundary: Repair the confirmed driver, antenna, module or board path.

Related cause to rule out

When a connection exists only with one router, cable mode or network type, also consider Laptop Wi-Fi System: network negotiation failure before choosing a repair.

Checks after the work

After repair or replacement, check both Wi-Fi bands, sustained transfer, roaming and sleep.
