I have traded the Intel(R) Centrino(R) Advanced-N 6200 AGN and the Intel® Centrino® Advanced-N 6235 adapter. I had to install the drivers from Intel's website, but had no problems.
You can try going to the Intel Download Center for the drivers you need.
Thank you very much for your post,
On regards to your question, please note that the Intel® Centrino® Advanced-N 6235 wireless adapter is meant to be professionally installed by Original Equipment Manufacturer (OEM) technicians on certified systems only.
Please also note that these adapters are not meant to be sold separately, 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.
In this case what we recommend and encourage you to first contact the Original Equipment Manufacturer (OEM) to determine if the product is approved for use in your computer.
