Note that the Intel® Wireless WiFi Link 4965AGN is meant to be professionally installed by Original Equipment Manufacturer (OEM) technicians on certified systems only.
Your system must be compliant with the required FCC certifications in compliance with the International Special Committee for Radio Interference standards for radiated and conducted electromagnetic interference.
It is possible that the computer you have is compatible only with Intel® Wireless WiFi Link 4965AGN that are provided directly from the same company that originally integrated the adapter in your system, therefore only specific versions of the card will work in it.
Try updating the BIOS of your laptop to improve compatibility and if that doesn’t work you might need to contact the computer manufacturer and get a Intel® Wireless WiFi Link 4965AGN directly from them.
Installing an aftermarket wireless adapter in your laptop can cause several issues which may affect usage of the wireless adapter or laptop. Some of these issues may include the following:
- The OEM may have installed the wireless adapter with a lock to prevent installation of another adapter.
- Your adapter may not be electrically compatible with your laptop that may cause the adapter and/or your laptop to no longer function.
- Wireless hardware installation and use is subject to regulatory approval, and the adapter purchased may not support your local regulations.

I found the problem. I still have the new 4695AGN adapter inside. Although, as JorgeR mentioned, some adapter might not work even though they are the same model, in my opinion this is very unlikely and I kept looking for problems elsewhere. I found out that the microchip on the audio jack board where the wireless switch is connected was damaged. I purchased and installed a new audio jack board and the wireless is functioning now.
This is an image of the damaged audio jack board. A replacement part is between $10-$20.
