All-in-One Computer 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

Record distance from the access point and time since startup. Compare another device at the same location before attributing weak reception to the computer.

Stop point: All-in-one housings may contain mains-power sections and should be opened safely.

Workshop confirmation and repair

Device-level check: Compare distance, bands, temperature, driver state and a known external adapter.

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

Repair boundary: Repair the module, antenna, software or board path confirmed by comparison.

Related cause to rule out

When a connection exists only with one router, cable mode or network type, also consider All-in-One Computer 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, restart and warm operation.
