It works at least for me, as AP and as STA...
But some people have different issues, looks like, mostly with old kernels.
You can find some of them:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/838016
http://pleph.appspot.com/init/posts/view/2657865

Check:
- PCIe related power managment - ASPM.
- WiFi related PM. "iw dev wlan0 get power_save"
- defect device?

Is it regression? Are there any working kernel version?
