[Steps to reproduce]
1. Power On system and boot into OS.
2. Validate the Wi-Fi interface is works via below steps.
  - Launch Gnome Wi-Fi Settings page to make sure the Wi-Fi interface works.
  - Launch Terminal, check Wi-Fi interface works through ifconfig command.
(If the Wi-Fi interface works, continue below steps)
3. Power cycle the system and check Wi-Fi interface again.

[Expected result]
The WiFi interface is listed in Gnome Settings page.

[Actual result]
No WiFi interface in Gnome Settings page.

[Failure rate]
3/74
