[gentoo-user] AC WiFi Card

[Ralf <ralf+gentoo@ramses-pyramidenbau.de>]

Hi folks,

I want to get rid of my old Wifi AP. As I already have a gentoo server
in my flat, I'd also like to use a Wifi AP using hostapd.
And, of course, I'd like to use the latest AC standard, as my laptop
supports it. Additionally, I'd also like to use good old 2.4GhZ as
fall-back.

So I was looking for some PCI-E Wifi Card, that supports AC standard. I
was thinking about sth. like this [1]. A friend of mine told me, that I
should take care when buying AC hardware, as there is rare kernel support.

Does anyone of you successfully use AC hardware in AP mode, Dual stack
(5GhZ / 2.4GhZ)?
What kind of hardware would you recommend (and is known to work without
any painful hacks)?

Cheers
  Ralf
