Loss of WiFi after migrating from Windows 10 to Windows 11

This is a driver issue, not a hardware or Windows 11 compatibility problem.

On the Dell XPS 8930, the Wi-Fi adapter is usually Intel, and after upgrading to Windows 11 the driver may fail to load. The iqw64e.sys message points to an Intel wireless driver conflict.

What to do:

• Check Device Manager

Open Device Manager and look under Network adapters.

If Wi-Fi is missing or shows a warning icon, the driver isn’t loaded.

• Install the correct Wi-Fi driver manually

Since you have no internet:

Download the Windows 11 Wi-Fi driver for XPS 8930 from Dell’s support site on another PC

Copy it via USB and install it manually

• Remove old Intel drivers (if needed)

In Device Manager, uninstall the existing wireless adapter and check “Delete the driver software”, then reinstall the Dell driver.

• Restart the PC

After the correct driver is installed, the Wi-Fi toggle and icon should return.

Summary:

You don’t need to go back to Windows 10. This happens because Windows 11 didn’t install a compatible Wi-Fi driver. Installing the proper Dell/Intel wireless driver fixes it.
