[Bug 111502] Re: network-manager unreliable with multiple APs

[Kim Toms]

I also have trouble using network manager.  I am updated to 9.04.  I had
apt-get remove'd network-manager a month or two ago, and instead used a
terminal window to manual type the wpa-supplicant commands.  This almost
always works instantly.

The network I'm attaching to is an open-mesh network with 3 nodes (all
visible from my laptop usually).

When I use wpa-supplicant from the command line, it gets connected in a
second or two, then I create another terminal and run the dhclient
command to get a network address.

Today, I installed network-manager using 'apt-get install network-
manager'.

This installed the following packages:
2009-07-22 07:29:29 install dnsmasq-base none 2.47-3
2009-07-22 07:29:29 install libnm-util1 0.7.1~rc4.1.cf199a964-0ubuntu2 
0.7.1~rc4.1.cf199a964-0ubuntu2
2009-07-22 07:29:29 install libnm-glib0 0.7.1~rc4.1.cf199a964-0ubuntu2 
0.7.1~rc4.1.cf199a964-0ubuntu2
2009-07-22 07:29:29 install libudev0 none 141-1.2
2009-07-22 07:29:29 install network-manager 0.7.1~rc4.1.cf199a964-0ubuntu2 
0.7.1~rc4.1.cf199a964-0ubuntu2
2009-07-22 07:29:30 install network-manager-gnome 0.7.1~rc4.1-0ubuntu2 
0.7.1~rc4.1-0ubuntu2

After rebooting, I could no longer get connected to the network using
the network-manager method.

I next removed the network-manager-gnome and network-manager packages
and, after rebooting, tried the wpa-supplicant method but it did not
work.  After a couple of minutes, I located the dpkg.log and removed all
of the other packages listed above.  I rebooted again, and now wpa-
supplicant works to get associated.

Additional information
System is Sony Vaio laptop vgn-sz470n
wifi driver is iwl-3945

There is another symptom, but I have not verified it well enough to
report it reliably.  It appears that after using the network-manager it
has affected something in the hardware, because it (may) be necessary to
shut down and remove the laptop battery for a few seconds before booting
the system and using the wpa-supplicant command-line method to get the
network connected.

[Bug 390274] Re: no wifi network with Intel Wireless 3945ABG under kernel 2.6.28-13

[Kim Toms]

I have sony VAIO w/ iwl3945 driver also.  Using network-manager-gtk I am
only occasionally able to get associated with an AP.  I am using APs
from open-mesh.com.

Looking at the wpa_supplicant.log in /var/log; I saw many timeouts of
attempted authentication.  Also, while attempting to associate I would
have the dialog box pop up several times before it just gave up.

I removed network-manager-gtk and tried to get more debugging info by using 
wpa_supplicant from the command line.
I was able to make associate using wpa_supplicant from the command line.
  
Is there a way to turn debugging up in wpa_supplicant from network-manager-gtk?
