Hi there,
I'm using a TP-LINK TL-WN721N, and experience a strange behaviour, I'm
running Ubuntu 13.04 (3.8.0-27-generic + backports-3.11-rc3-1).
The problem is that if I am connected to my AP and then power it off, I
never receive a disconnect notification.
I first reported the bug to the connman mailing list [1], but it was
suggested there that it could be a bug in the device driver.
At first I was using the Ubuntu kernel modules, but before reporting any
bugs, I switched to backports-3.11-rc3-1, and I still have the problem.
Any thoughts?
Regards,
Chris

I assume it is firmware issue - no idea right now. You can open ticket
on open-ath9k-htc-firmware but do not expect it to be fixed soon :(

Yes, it is.
I have just tried latest firmware from git, it is still not working as
expected. Ubuntu 13.04 comes by default with FW v1.3, I can confirm that
I really used the new one, as now the kernel tells me it is FW v1.4
(before it was 1.3).
Should I open an issue ticket on open-ath9k-htc-firmware? How can I make
sure where the problem comes from?

I assume it is Atheros ar9271 based adapter. Did you tried to use latest
firmware?

If you have some time, i'll suggest you to investigate this issue so far
you can by your self.
