- Check Device Manager again for wireless adapter.
- If wireless adapter still does not show in Device Manager, use System Restore to restore to an earlier date when wireless adapter was working.
- If issue still persists, perform a System Recovery to determine whether the wireless card has failed.
NOTE: On some models, Wireless and Ethernet adapters can be disabled in the BIOS.
