Einleitung
Sometimes a faulty wireless card causes network connection issues, and replacing the card should alleviate them. You’ll need to remove the keyboard as a prerequisite, requiring a PH0-head screwdriver, a rigid pry-tool, and some gentle care needed when opening the ZIF connector. The rest of the process is fairly simple.
