Laptop Wi-Fi System: severe radio interference. Another transmitter or congested channel overwhelms the intended wireless link.

The distinguishing clue

Signal bars may look strong while speed and latency are poor.

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: Compare bands, channels and a wired link in the same location. If confirmed: Change the radio environment or configuration rather than replacing good hardware.

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

Related cause to rule out

When performance improves only very close to the access point or device, also consider Laptop Wi-Fi System: disconnected antenna lead before choosing a repair.

Checks after the work

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