I see that your BIOS has the whitelist. Sad to say that only certain FRU P/N cards will work with your Gateway. Look at your repair manual for the laptop and it'll have a FRU P/N list of WiFi cards for your laptop. Go to something like "pc hub" where they sell those FRU P/N approved WiFi cards.
There are several OEMs that limited which hardware is compatible with their system.
We recommend contacting the Original Equipment Manufacturer (OEM) to determine which product is approved for use in your computer. Only your system manufacturer is entitled to provide the list of validated and certified adapters that are compatible with your system and the proper means to do the hardware exchange for you.
If the Insyde bios has a whitelist that allow you to enable this adapter you may want to try, but once again, you would need to contact your system manufacture.
In addition, your system is currently certified with the FCC in compliance with the International Special Committee for Radio Interference standards for radiated and conducted electromagnetic interference, installing any other adapter might void this certification.
