Is there something we can do besides taking this Gateway laptop back for a refund ?

My niece purchased a Gateway laptop with Windows 8.
While cleaning the keyboard, she pressed all the keys at once,disabling the Wi-Fi but when she tried to re-activate it by pressing F3, she was not able to do, then she tried pressing Fn + F3….. nothing !

Device manager Network adapter states: Qualcomm Atheros AR5B125 Network Adapter—- device working properly and software up to date.

Network & Sharing—Change adapter settings——states; Wi-Fi not connected but when connect is clicked nothing happens.

Every diagnostic check states the same:
Problem found : Wireless capability is turned off.
Turn on wireless capability (use the switch on the front or side of the computer) but pressing F3 just toggles the on/off airplane mode and Wi-Fi (off) remains unaffected and no available Wi-Fi networks are visible.
We have tried rebooting the laptop then restoring back to factory condition and re-installing the driver as well as the wireless card itself to no avail.

Most people advice is to informed us how to activate the Wi-Fi adapter (We know how to do so ) or to install BIOS version 2.06 from the Gateway support website ??
The laptop is not able to get online,that’s like telling someone on the side of the road with a completely disabled vehicle that they need to drive to the nearest garage and have the problem fixed.

The laptop is an expensive doorstop !! We’d rather not take it back to the store for a refund.
What else can be done ?
