[Bug 602649] Re: wireless hangup for iwlagn kernel module, if 802.11n enabled

[Gustave Salut]

Dear all,

I would like to report a bug happening with the Wlan connection of my
laptop hanging up sporadically, be it out of the blue, or after resuming
from hibernate.

I suppose it is the same bug nevergone reported.

It happens with my laptop, a Lenovo X61t (Intel 802.11agn) running
LinuxMint9(64bit) as well as with my partners T60 (Intel 802.11abg
wireless) running LinuxMint9(32bit) and a friends T61 running Debian
Lenny. This friend (who is administrating computers at my work) gave me
a workaround skript which simply reloads the concerned kernel-modules.

#!/bin/bash

if [ "$UID" != 0 ]; then         #get necessary rights
  exec sudo "$0" "$@" || exit 1
fi

ifdown wlan0                     #usually not necessary, as it is already down
sleep 1
rmmod iwlagn iwlcore             #on the Debian Lenny, it is rather "rmmod iwl4965 iwlcore rfkill"
#s2ram                           #my friend pretetends he sometimes has to suspend again to get it to work, but this may be a myth
#read -p "Suspend now." a
sleep 1
#pm-suspend
#sleep 5
modprobe iwlagn
sleep 1
restart network-manager         #so that the connection comes up again automatically 


This works fine, but remains annoying. 

Today, the hang-up happened out of the blue again, and I thought this
might be the time for my first bug-report. Please be indulgent if this
is not the same bug. etc.

I attached all logs with entries from these few minutes. There are

messages
syslog
daemon.log
debug
kern.log
mail.info
mail.log,

all in one file.

What happened: 
At 18:21, I got this pop-up message that I was deconnected. Before, a download was underway. 
At 18:22, I was asked for the password of the connection, which I denied to enter, knowing that it would not work.

Meanwhile, my partner continued surfing unbothered.
