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 Atheros ar9271 based adapter. Did you tried to use latest
firmware?
https://github.com/qca/open-ath9k-htc-firmware

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