This is a driver issue after the Windows 11 25H2 upgrade, not a hardware problem.

The missing Wi-Fi toggle/icon means Windows has no working Wi-Fi driver. The iqvw64e.sys error is related to Intel PROSet / wireless components failing to load after the upgrade.

Fix (no rollback needed):

  1. Get temporary internet (Ethernet or phone USB tethering).
  2. Install the Windows 11 Wi-Fi driver for Dell XPS 8930 from Dell Support (do not rely on Windows Update alone).
  3. Reboot.
  4. If needed, uninstall Intel PROSet / Wireless Software, then reinstall the Dell driver.

Wi-Fi should reappear immediately after the correct driver is installed.
