[TL-WN721N] No disconnect notification when AP is gone

[TL-WN721N] No disconnect notification when AP is gone

[Christian Gagneraud]

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

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

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?

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 :(
