I'm using Debian/sid with a custom-built kernel (version 2.6.25.4) and

included with the
kernel.
Setting up the internet connection using nm-applet to my
wireless network
with WPA encryption works seamlessly. Instead of shutting down
my laptop I
am normally just sending it to sleep in order to quickly have it
back up
when I need it. The only problem comes up right after waking up:
Reconnecting to my wireless network takes usually more than one
minute - a
really annoying issue. Checking /var/log/syslog the output of NM
shows the
following:
[...log messages deleted...]
..and so on. After this, a connection is successfully
established. Note that
between "Jul 18 19:32:29 Kati-PC NetworkManager: <info>
Deactivating device
eth0." and the next message "Jul 18 19:33:39 Kati-PC
NetworkManager: <info>
SWITCH: no current connection, found better connection 'eth1'."
1 minute and
10 seconds have passed (though this time period varies). Btw.,
when trying
to scan for wireless networks within this time period using
"iwlist eth1
scan", it shows me all available networks correctly. Trying to
manually
reconnect using the nm-applet is not possible as it does not
show any
wireless networks until it reconnects.
I have another laptop, though with an Intel 2200 wireless card,
but the same
kernel version and OS, and there this time period is usually
down to only 10
seconds or so, making it reconnect much faster.
Is there any way, any setting to speed up reconnecting? This is
really the
only issue I encounter, otherwise NM works just great.
I often see the same behavior in Fedora 8 (currently
NetworkManager-0.7.0-0.6.9.svn3675.fc8.x86_64 and also the iwl3945
driver). (Didn't look at the log messages, but the rest of the
description is accurate for me as well.)
