Hi everybody !
I've got exactly the same trouble:
HP-14-TS:~$ apt policy network-manager
network-manager:
Installé : 1.36.4-2ubuntu1
Candidat : 1.36.4-2ubuntu1
Table de version :
*** 1.36.4-2ubuntu1 500
500 http://fr.archive.ubuntu.com/ubuntu jammy/main amd64 Packages
100
Same problem on Ubuntu 22.04
corrado@corrado-n3-jj-0103:~$ apt policy network-manager
network-manager:
Installed: 1.32.12-0ubuntu2
Candidate: 1.32.12-0ubuntu2
Version table:
*** 1.32.12-0ubuntu2 500

I'm going to bump this, as the last report was years ago. I'm now
experiencing this issue on a Qualcomm Atheros AR938x device I've had for
years now. Same issue with constant disconnects as well as a new issue
that might involve iommu?
[ 680.361521] ath9k :21:00.0: AMD-Vi: Event logged
Good Morning,
I'm recording in this report that I am also being affected by the bug
described above. Remembering , reported 4 years ago .
Thanks.

The networkmanager connects at my place to BSSID none. None does not
exists, so the connection is lost and restarted again, and again and
again.
The relevant log is:
info (wlan0): roamed from BSSID (none) ((none)) to 7C: (Zadel6)

I added a registration to iw:
sudo iw reg set US
This seems to have solved many of the problems that I have been having
with random disconnect

FWIW, still broken on 14.04, the workaround of manually fiddling with
the NetworkManager config still helps.

I apologize if this is the wrong bug.
I do have the same problem. On my machine the Networkmanager links up
with a SSID that is the strongest access point (of my neighbors) , but
that access point is not configured. Hence, the link dies, takes some
time to recover and then the sequence starts
I think there is a second bug connected with comment 51. That is that
Networkmanager THINKS that an access point is stronger. I checked my comment an
other machine. On that machine the wrong SSID 'linksys' was NOT stronger. On my
machine it was.
After a rescan the strength of the connection
Adding to comment 52. The frequencies of the access point are the same.
In this example Channel 11. Is the networkmanager getting confused and
makes it a connection to the incorrect access point? All evidence points
in this direction. It explains also the wild changing of the signal
strength.
A
I switched to channel 13. Less problems but if the Internet connection
is (shorter) blocked I get:
Or:
sudo iwlist wlan0 scan
wlan0 Interface doesn't support scanning : Device or resource busy
Or:
wlan0 Scan completed :
Cell 01 - Address: B0:B2:DC:10:33:6C
How this bug can still be going today amazes me. I experience this type
of unstability on my ASUS UX31E as well. Wireless card is an Ahteros
AR9485.

All the above attachments are uploaded after the bug occured and I reset
the router to have internet access. Right now, a few minutes later, I
have it again. It's not a great computer experience... :(
I can provide with any log and other information one would need to fix
this, even remote control
The last set of attachments are after the second router reset and sudo
apport-collect 495981. Maybe some other way of collecting local data
while the bug is active would be better? In this version, I can only run
this command if I reset the router and I reconnect on the wifi
connection

I just subscribed you to this report, so now I hope apport-collect will
work. Please reboot, reproduce the malfunction, then open a terminal
and run sudo apport-collect 495981.

I tried that, but (of course) it does not work as when the bug occurs, I
do not have an active internet connection.
Restarted the wifi router and ran again the command. This is the output:

@florin: Can you please attach a new syslog covering one of the

deauth by local choice (reason = 3); most likely because the background
scans are causing this particular driver to deauth from the AP for
scanning.
Is this still the case in 12.04?

I have always blamed the driver for this (and nothing happend from that
side), but seeing this might change my mind. It is very frustrating to
use ath9k (even the latest version, manually installed) and not to have
a reliable internet connection.
It is not every 2 minutes, it is once a day or
And as a completion: this is very old, at least since Natty (the time I
switched to linux). I now use Ubuntu Precise (12.04).
