Cable network adapter has disappeared from the Device Manager. No cable connection available.

Hi!

The cable network adapter has disappeared from the Device Manager. I no longer have a cable connection, just Wi-Fi on a separate adapter. Realtek Network Diagnostic application does not detect the network adapter and neither does Dell Support Assist System Information application.

- Ethernet NIC:  Realtek PCIe FE Family Controller.

- Notebook model: Dell Inspiron 15R SE 7520.

- Operating System: Windows 10 Professional - version 1703 Bld 15063.332. (Creators Update ...).

- Overall update status: BIOS version is the latest "A11" and all installed device drivers are those currently recommended by Dell web site.

- Note: Network cable itself is OK and the network provider signal exists as other PC’s do not show connection failures with the same cable when tested individually).

I would appreciate any help to solve this problem. 

Thanks in advance.

Mendes_BR,

Install/reinstall the chipset drivers, reboot the computer and then install the network card drivers.

Hi, Jesse.

Thank you for your prompt reply.

I followed your recommendations but I did not get the expected results. Windows still does not detect the Ethernet network adapter and I still do not have wired connection . I also checked the BIOS and made sure the network is enabled so I do not know what else I could do.

Thank you very much and if you have additional suggestions please let me know.

Regards,

Mendes_BR,

Uninstall the creators update. Reboot the computer and then reinstall chipset drivers and reboot the computer. You can then try installing the network drivers.
