If your Chromebook’s wireless or cellular connection is patchy, non‑existent, or acting erratically, the culprit may be the internal network card. The Cr‑48 Chromebook shipped with a combined Wi‑Fi and cellular network card that is accessible and replaceable using this guide.
The repair is needed when you notice symptoms such as loss of Wi‑Fi, inability to detect networks, intermittent connectivity, or cellular data failure (if your model supports it). It’s also possible the card has become physically loose or was exposed to moisture, which might degrade its connections.
Before you begin, it’s important to power down the device completely and remove the battery so you avoid any risk of electrical shorting.

The card identified in the pictures is not a combined Wi-Fi / Cellular card. It is just a 3G cellular card; the WiFi card is the other card tucked under the flat ribbon next to the card pictured in this guide
