Realtek 8191S WLAN Adapter Driver

I have an Acer Aspire e5-575g-53vg laptop with Centos 7 and an up-to-date kernel 4.7.3-1.el7.elrepo.x86_64. Acer says my wireless adapter is an Intel Wireless-AC 7265 (any way to verify this without having to take the laptop apart?) but lspci is not showing this device. I downloaded the linux drivers and put them in /lib/firmware as it says on the site, however I don't know what to do next.
