This guide will show you how to replace the Wi-Fi card in a Lenovo ThinkPad T470 laptop.

A Wi-Fi card, also known as a WLAN card, enables the laptop to connect to a wireless network. If you cannot connect your laptop to Wi-Fi, or if you are experiencing intermittent connectivity, you may have a faulty Wi-Fi card. Be sure to rule out other connectivity issues listed here before replacing your Wi-Fi card.

Make sure to disable the internal battery, power down your device, and disconnect from any external power sources before you begin.
