>Another thing you may want to experiment with is if the Intel 7260AC wifi card works in that model.
Wow, this card is supported by Intel and driver version is 21, so if it would work with my card, then I am lucky.
This driver (as any Windows driver probably) has .inf file with list of PCI ID of all cards it supports, it could be that it has my card ID.
>There is a possibility your notebook does not have a BIOS whitelist. I can't say for 100% sure, but it is possible.
I read about it somewhere on this forum: there were a guy who said 4540s has whitelist.
Some people on the Internet even created hacked versions of BIOS with whitelist removed (something I really do not want to try, because it can brick my laptop and I do not have hardware programmer to fix it).
Unfortunately, I do not have 11ac card to try, and even if I were, almost all 11ac are M.2 and my laptop only has Mini PCI-E. There are adapters for that, but I am not sure it they would work correctly..
Anyway, I will try both: driver from the Catalog (which Windows should install automatically I suppose) and 7260AC driver.
