Come to your new pen drive or hard disk and create a new folder named USB and copy all the files from the driver folder.   Once you are ready with the two storage devices, a bootable pen drive with software and another storage device with Intel Rapid Storage Technology (IRST) Driver, go to your broken laptop.

Given you have completely wiped your PC, there is a high possibility that your PC might not have Wi-Fi drivers.
