Bug Description

When resuming from suspend or hibernation I'm not able to associate with an access point. I can see all available AP's but it refuses to connect to them. That goes for both wide open and WPA protected AP's.

I've tried putting ipw3945 into /etc/default/acpi-support module list but that didn't help, also tried the whitelist just for the sake of it.

I've tried to unload all ipw3945 related and NetworkManager before going into suspend but that didn't make any difference.

I've tried to disable network through the nm-applet and enable it again to no avail.

I'm running Feisty on a Thinkpad T60 with latest updates (2.6.20-15-generic).

The syslog report the following (and it just goes on and on like this, eth1 is the wireless interface):

I am running Feisty on an Acer Aspire 5650 with latest updates (2.6.20-16-generic) and I am experiencing the same problem. This stops me from using Hibernate mode. Currently I don't have an opportunity to use any power safe modus, because Suspend To Ram is completely broken (this is not related to ipw3945).

My computer with Xubuntu feisty had a problem with getting an ip-adress after waking from hibernation. I´ve solved this problem by changing /etc/default/acpi-support

Editing this file, look for the line below, where to add [networking] after that no problems anymore:

# Add services to this list to stop them before suspend and restart them in
# the resume process.
STOP_SERVICES="networking"

Hope this will work for you to,
Thomas.

Thanks Thomas!

I've tried it out and it seems to work out just okay. Not that it is perfect, I still have to disable/enable networking through network-manager before it re-associates to my AP, after resume from suspend or hibernation.
But now at least I have a way to make it work without rebooting (just too much Windows over that solution ;ø) )

Sorry Thomas (de Graaff). Your suggestion does not work on my Acer Aspire. I also tried Thomas (Dahlmanns) suggestion and disabled/enabled networking through the network-manager, but no success at all. Seems I have to stick with my (sad) situation a little bit longer. Thanks anyway, it was worth a try.

rapequ, have you tried the "modprobe" trick (modprobe -r ipw3945; sleep 1;modprobe ipw3945)?

rapequ (ralfq) wrote on 2007-06-18:

Thanks for the hint Thomas. Yes I tried it and had no success. After my machine woke up from hibernate the network manager tried to establish a connection. Note: I cannot disable/enable the network before the network-manager tries to re-associate with an AP because the network-manager already tries to establish a connection when resuming after hibernate.
I tried your "trick" after the network-manager failed to establish a connection.

Anyway, thanks for your suggestion!

I also have this problem (only noticed it in Gutsy, but FGLRX hasn't let me suspend since Dapper or Edgy)... I can sometimes fix it with:

sudo killall `ps aux | grep ipw3945d | grep -v grep | awk '{print $11}'`
sudo rm /var/run/ipw3945*.pid
sudo rm /var/run/dhclient.eth1.pid
sudo rmmod ipw3945

sleep 2

sudo modprobe ipw3945
sudo /etc/init.d/dbus restart

If that doesn't work, I try rmmod ipw3945, /etc/init.d/dbus stop, hit the wireless kill switch (Fn+F2 on my Inspiron), then bring ipw3945 and dbus back up.

It's pretty annoying... a proper fix would be nice.

I second ThomasDahlmann's questions: It is very annoying and stops me from using hibernation. Please fix this issue. All of the suggestions provided here don't work in my particular case.

I am using feisty and have been experiencing the same bug since some month ago (may be an upgrade). I can't even associate using iwconfig, however I found the following workaround: when I use iwconfig to associate to the AP, I also specify the channel as follows

iwconfig eth1 ESSID <MY_ESSID> mode Managed channel <MY_CHANNEL>

Channels can be listed by issuing the command "iwlist scan".

This suffices to associate to the AP, and makes the subsequent "dhclient eth1" work and obtain an address.
