Wi-Fi Antenna Connector

Small coaxial connectors (U.FL/IPEX) that attach laptop antenna cables to the wireless card.

Definition

Laptop Wi-Fi antennas usually run through the display hinge and lid to the M.2 wireless card. Disconnected or pinched antenna leads after repairs cause weak signal. Main and auxiliary leads must be connected to the correct terminals.

Example

Poor Wi-Fi after a screen replacement: reconnect the antenna leads to the M.2 card.

Exam tip

Weak Wi-Fi after a display or hinge repair often means an antenna lead problem.
