Explanation

When replacing a wireless network card in a laptop, the internal Wi-Fi antenna cables (typically two thin wires routed through the display lid) must be reconnected to the new card. If these antenna cables are not properly seated or are left disconnected, the wireless signal will be significantly degraded, resulting in very limited range. This is the most likely cause after a card replacement. Switching frequency bands, changing channels, or updating drivers would not resolve a hardware antenna connection issue and are not the logical next step immediately after a card swap.
