Hi EddieHacks,
As per the above image, WLAN card is detected in Device manager, and as Ethernet card is not detected in device manager I would like you to check in BIOS if the “Onboard LAN controller is enabled or disabled. To check please follow the below mentioned steps:
- Restart the system by tapping F2 at Dell screen.
- Select “Advanced” tab in the BIOS page.
- Select “System Configuration” and check the option besides “Onboard LAN controller”, if it is “Disabled” please “Enable” it.
- Press F10 to save the changes made and Exit the BIOS screen.
Check if the Ethernet controller is detected in Device manger, if it is detected try to plug in an Ethernet cable and check for network connection.
Please reply for further help.
