I'm surprised how long this bug has been around. It has been affecting
me since I installed 12.04 on a T410si ThinkPad with an RTL8191SEvB (pci

I also get a very unstable WiFi connection on enterprise networks that

Installing wicd makes this problem go away. Here's my story.
I have a wireless network with a 802.11g dlink router and WEP key. I use
two machines, a MacbookPro revision 4 with a Atheros Communications Inc.
AR5008 Wireless Network Adapter (rev 01) and a mac mini.
The macbook pro runs ubuntu 9.04
FWIW, several months ago I got fed up and hacked around this by just
commenting out a key schedule_scan call in NetworkManager. I no

Regardless of whether I am connected or not, when I open the NM menu to see
broadcast networks, it is going to have to scan then, right?
No. Opening the menu only shows you the results of the last scan,
whenever that was. It doesn't initiate a scan.
So if that scan causes me to temporarily lose
Hi, unfortunately, this patch does not entirely fix my problem. I'm
seeing roaming to (none) ((none)) less frequently, but it is still
happening. Likewise I still have between 10 and 45% packet loss due to

Alex - this patch turns off scans while an A/B/G card is associated to
an AP. That means whatever was in the scan list when the connection was
started is all that the nm-applet (or the nm=-ool) will show you, for
the duration of that association - it won't update by itself. Of course,
a superuser
So despite the broad cross-section of drivers being affected, Dan
Williams on the networkmanager team still thinks this is a driver bug,
and still thinks that periodic scanning is a good thing (completely
ignoring the network lag it causes whenever a scan is done). See his
followup:
I would suggest that people may also want to complain here:
