First of all, double check to see if the Wifi is enabled. To enable the WiFi, go to Settings -> WiFi -> Enable and connect to a wireless connection. Once this is checked and the problem has not been resolved yet, the WiFi adapter may need to be replaced. To replace the WiFi adapter, follow our [[Mid F900 Troubleshooting#Section_WiFi_Disabled|guide]] for replacing the WiFi adapter.
