Introduction

The WWAN (wireless wide area network) card allows you to connect to the internet without relying on a local Wi-Fi connection. If your computer has a WWAN card installed and you are having trouble using the internet without Wi-Fi, you may have a faulty WWAN card or antenna.

If you are having trouble accessing a local Wi-Fi connection, you may need to troubleshoot or replace the Wi-Fi card or WLAN antennas.

Before attempting a replacement, make sure to disable the internal battery, power down your device, and disconnect from any external power sources.

              Bottom Cover
  • Disable the battery, power down the device, and unplug the power adapter from your device before proceeding/beginning the guide.
