I'm looking to add Wireless-AC capability to my HP Elitebook 9470m. The OE wifi card is an Intel N6235 and it is constantly dropping connections. I want to fix that problem but I'm also upgrading my home network to wireless-AC so I wanted to upgrade my wifi card as well. It looks like there are two options, an Intel 3160 or Intel 7260 card. I'm not sure of the difference between the two, that is what I'm going to dig into now.
I have read that HP locks the BIOS to only work with certain cards, does anyone know if that is machine specific or will any Intel 'Approved Card' work? Meaning, if I figure out what wifi card they use in the newer elitebooks (that supports wireless-ac) and buy that card and install it - will it work as it is not whitelisted/blocked from BIOS?
Thanks for the help guys, this is an amazing resource!
