wireless networking disappears in Hardy Heron Beta after waking up from suspend or hiberante

[Farhad]

I had Ubuntu 7.10 on my Toshiba laptop for a while and everything was fine. I installed the Hardy Heron Beta the first day it came out. The suspend was working fine until last week when after installing an update (I don't know which one!!), my wireless networking completely disappears after waking up from suspend or hibernate. If I right click on the network manager tray icon, I can only see wired networking!! I searched a lot on the web and tried lots of different things (like restarting iwl3945, restarting /etc/init.d/networking,......), but nothing worked except the following:
sudo /etc/init.d/dbus restart

then running nm-applet again.
However, in this way my system usually dies after few minutes and also if I suspend again it does not wake up. The only way I found is after running nm-applet, pressing ctrl-alt-bkspace and logging in again. I would appreciate it if someone could fix this bug.

thanks

Please attach the output of lspci -vv. Thanks.

Here is the lspci -vv before and after suspend.

thanks.

I just realized that VLC has no sound after waking up from suspend, but Totem still has.

Please attach your dmesg output too. Before and after suspend, maybe it's helpful.

After last updates to Hardy, Wireless Network is unreachable after resume from suspend to ram.

IBM Thinkpad X41 Tablet.
Hardy Uptodate.

This is a core problem, it is not dependent on Gnome or other graphics apps (I use wicd).
I tryed in console:

/etc/init.d/network restart
ifdown and ifup eth1
rmmod and lsmod ipw2200

Physically off and on laptop wireless.

Without results. I need to reboot system.

I am having this problem with my Inspiron 1420n laptop. I can confirm that restarting dbus and re-running the network applet works. Reloading modules or restarting the network service have not worked for me.

Also happens on Dell D630 using iwl3945.

Same thing here for me on a Lenovo R61, though I've been restarting hal to get it back (/etc/init.d/hal restart). It worked when I first upgraded to Hardy, but broke last week sometime. Within a few seconds of restarting hal, nm-applet finds my wireless network and automatically connects to it.

This is with an Intel Corporation PRO/Wireless 3945ABG Network Connection (rev 02)

Farhad, your dmesg output shows that your machine is trying to use an interface called wlan0_rename. This means that this bug is a duplicate of bug 183968. You can find a permanent workaround for the problem at that bug page: https://bugs.launchpad.net/bugs/183968

If anyone has a problem after applying the bug 183968 workaround, please file a new bug, and explain that you already tried the bug 183968 workaround. You may want to attach /etc/udev/rules.d/70-persistent-net.rules to the new bug, as well as the output of dmesg and "lspci -vvnn".

If your problem is gone after applying the bug 183968 workaround, you do not need to do anything more. Bug 183968 is well understood and developers are working on it.

Note also that any problems with sound or non-networking things are also a separate bug.

I think this is not a duplicate bug, because is new, i have been months with hardy without this problem, and before that, with gutsy. It appears after updates to hardy in these last weeks. And it requires a long time suspension/resume to manifest. In my previous message is my lspci. I dont have dmesg log but I dont belive is related to any wlan0_rename stuff, my system uses eth1 for wireless.

Thx.

Or maybe my bug requires another new thread.

For most users the suspend problems for bug 183968 have only shown up in the last few weeks (what happened was that an upgrade to pm-utils meant that the wireless drivers were being reloaded on upgrade, this made bug 183968 start affecting resumes).

Since Farhad filed the bug and his/her dmesg DOES show a wlan0_rename interface, this particular bug does seem to be a duplicate and you probably should search for or file a different bug, especially since you seem to be using ipw2200.
