You're very welcome.
Go to the device manager, click on the unknown device needing the driver.
Click on the driver tab. Click on Update Driver.
Select the Browse my computer for driver software option, and browse to the driver folder that was created when you ran the file.
That folder will be located in C:\SWSetup\sp75506.
Make sure the Include Subfolders box is checked, and see if the driver installs that way.
It definitely is the driver you need for that device.
Here is a partial copy and paste of the driver setup information file which shows driver support for the unknown device hardware ID...
[Manufacturer]
%INTEL% = INTEL, NTamd64.6.1, NTamd64.6.3
[INTEL.NTamd64.6.1]
%INT3400.DeviceDesc% = EsifManager,ACPI\INT3400
Yes, you will not be able to connect via wifi unless you remove the wifi adapter and mask a couple of the contacts.
You didn't want anyone to tell you to reinstall W10, so I didn't, but your notebook was not engineered to run W7.
See this discussion for the contacts to mask so the wifi card will work on W7.
Here is the link to the service manual...

Unfortunately, these are the kind of things you have to do in the name of W7.

Hi:
For the second device and one of the third devices, you need this driver.
Download, unzip and run the setup application, and restart the PC.

For the first device and the remaining third device, you need this driver...
