There was a problem when I tried to download drivers from Intel Download Center (images at the bottom). It was sort of a mission to find them other way around.
If anyone is googling for a direct link for drivers here it is:

Problem with download center
BEGINING OF PROBLEM DESCRIPTION
step 0 open a web-browser (in my case Google Chrome)
step 1 visit https://downloadcenter.intel.com
step 2 search for: N 6235
step 3 from product category box select "Wireless Networking"
step 4 from product line box select "Intel Wi-Fi Products"
step 5 from product name box select: "Intel Centrino Advanced-N 6235 (22)"
you will end up on page saying "Page Not Found"
END OF PROBLEM DESCRIPTION
Update:
Several weeks ago I reported this issue to Intel customer service, from the attitude of how they keep on sending me same auto-generated emails, this issue won't be solved so easily :)
