Laptop Wi-Fi System: disconnected antenna lead. The radio works but receives and transmits with greatly reduced signal.

The distinguishing clue

Performance improves only very close to the access point or device.

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: Inspect delicate coaxial plugs and compare signal per antenna. If confirmed: Reconnect or replace the antenna lead and restore routing.

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

Related cause to rule out

When signal bars may look strong while speed and latency are poor, also consider Laptop Wi-Fi System: severe radio interference before choosing a repair.

Checks after the work

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