Введение

The Wi-Fi card communicates with your wireless network through the router. If it is in range, your laptop will be able to connect to the internet if it's not password protected. If your Wi-Fi card is failing, follow this guide to replace your Lenovo ThinkPad T480 Wi-Fi Card.

The main symptom of a failing Wi-Fi card is problems with connectivity—more specifically failure to locate wireless connections, intermittent wireless connections and loss of connectivity due to hardware damage.

Prior to beginning this guide, be sure to disable the internal battery, power off the device, and unplug the laptop from the charging cable.
