This guide will show you how to replace the Wi-Fi card in a Lenovo V15-ADA laptop.
The Wi-Fi card is what lets your laptop connect to wireless networks, so you can get online without using an Ethernet cable. If your laptop isn’t detecting Wi-Fi or keeps disconnecting, the card might be damaged or faulty. Replacing it can often fix those issues.
Before you start, make sure to turn off and unplug your laptop. When working inside the device, handle parts gently and avoid touching any exposed metal to prevent static damage.
