Bug Description
Often, after resuming from suspend, NetworkManager no longer recognizes any network interfaces. It logs the following messages when this happens:
Jan 23 04:51:13 localhost NetworkManager: <information>
Jan 23 04:51:13 localhost NetworkManager: <WARNING>^I nm_add_

Hi, Kees,
Actually I thought that I was - I don't remember having to install anything
special, but this has been six months. Can you point me at some info so I
can try the stock NM?
Thanks very much,

I encounter this intermittently (but frequently) on Edgy as well. I'm running Edgy on a Sony VAIO S260 which uses the ipw2200 driver for wireless support. Using network-manager 0.6.3-2ubuntu6. It has happened both after resume from suspend to RAM as well as resume from hibernate.

Restarting NetworkManager fixes this consistently for me, so I don't think it's a kernel issue. So far, the cause is not yet known.

I've experienced it on Feisty with an ipw2200, though I haven't been
successful at reproducing it when I try.

In my laptop system with one wifi card (ipw2200) and one ethernet card (both built in), I think the problem is caused by changing interface names: After system boot, the network devices are named eth2 and eth3, eth0 and eth1 don't exist. Network Manager works.
After a suspend, the devices are called eth0 and eth1, so Network Manager doesn't find them anymore. I can still configure the renamed devices using ifconfig and iwconfig.
Restarting Network Manager doesn't have any effect.

The problem may be related to Udev, I suppose.

Hi,
Just to let you know I'm running Feisty (herd 5) on a Dell D610. Using a wired network I get similar problems (the network often fails to get a IP address from DHCP after resume if the lease has expired).
Restarting the computer causes it to successfully get a IP address.
Also, it is not a problem with kernel modules. When NetworkManager fails to get an address, I can disable it, go to command line and
$ sudo su
$dhclient3 eth0
and my computer will be on the network no worries.
Let me know if you want more info about my system.

Please try to fix this bug, it happens on 2 of my 3 laptops with Feisty. It is easily reproducible here after you sleep/wake-up a laptop about 5-6 times in a row. IMO, this bug should be upgraded to "high" because it seems a lot of people have it.

I have the same problem with a fully updated Ubuntu Feisty on a Desktop (DELL Dimension 4700). I'm trying to use Hibernate or Suspend as they save energy (compared to leaving the computer on) and time (compared to a full shut-down/restart). Not being able to use the network half the time after Resume from Hibernate/Suspend is a serious usability issue for me.
I'm sorry to say that I'd never had this problem with Windows XP Pro or XP Media Center Edition. I also don't remember this problem with Ubuntu Edgy. The network was just re-detected immediately. Feisty risks being perceived as not environmentally
With Feisty, it sometimes helps to use System > Administration > Network > Configure, and change the Wired Connection > Properties from DHCP to Local Zeroconf, and then back to DHCP again. But other times, it does not help.
I have the following WIRED Ethernet card: Intel Corporation, Device: 82562ET/EZ/GT/GZ - PRO/100 VE (LOM). Network device: eth0
Hardware address: 00:13:20:0e:ce:fb. I use DHCP networking via my wired router.
Background: Suspend or Hibernate only work when I use the open-source ati video driver, not the closed-source one that the Update Manager recommended after upgrading to Feisty. I'm not sure if it's related, but I'm mentioning this just in case.
Thanks in advance for your prompt attention to this matter.

In my case I had to:

Without turning of eth0 first running dhclient resulted in successful ip renew from dhcp-server but network was not working.
Turning off/on network in Network Manager wasn't helpful.

philly (phburks) wrote : Beagle was somehow interfering with Network Manager | #30 |
I was having this same problem with Edgy where after 2 or 3 suspend/resume cycles Network Manager would not recognize my network interfaces (using a notebook with built-in intel wireless). I was also using Beagle for my desktop search. I don't know why, but when I killed the beagled process my problems with Network Manager disappeared. Every suspend/resume cycle worked flawlessly, with Network Manager reconnecting on every single resume. Not wanting to lose my desktop search, I removed Beagle and replaced it with Tracker, which also integrates with the Deskbar Applet. I had no more problems with Network Manager not resuming after that.
For whatever that is worth, there it is. I can't explain why it worked, but it did.

This is probably coincidental; plenty of folks are having similar problems
with Network Manager without using Beagle.

I have a Dell Latitude C610 using a Linksys Wireless card (using the ndiswrapper driver). The card would automatically reconnect successfully in Edgy; in Feisty it will occasionally _not_ reconnect after resuming from a suspend to RAM session when closing the lid.

Carl,
I've confirmed that this change fixes the wireless resume problem for both
hibernate and suspend on my Gazelle Pro. Yeah!!!!
I'd say that this is something to be rolled into the next version of the
System76 driver. I don't know if the other laptops need it, but it
certainly appears that the Gazelle Pro does.

I've tried the fix suggested by Matt Zimmerman on 2007-05-23 (see https:/
Moreover, when resuming from Suspend (not Hibernate), my computer just hangs sometimes, with a blinking white cursor at the top left of a black screen. Restarting with Ctrl-Alt-Del only gets me as far as the GNOME "Loading Desktop" splash screen before there is another freeze-up. Everything finally clears up after I restart X by doing Ctrl-Alt-Backspace. (The networking also seems to start working at that point.)
Note: restarting X does not seem to help restore networking after resuming from Hibernate. It does sometimes help to use System > Administration > Network > Configure, and change the Wired Connection > Properties from DHCP to Local Zeroconf, and then back to DHCP again. This seems to work more consistently now than before I had tried the fix.
To recap, I am using Ubuntu Feisty (fully updated) on a Desktop (DELL Dimension 4700). I have the following WIRED Ethernet card: Intel Corporation, Device: 82562ET/EZ/GT/GZ - PRO/100 VE (LOM). Network device: eth0. Hardware address: 00:13:20:0e:ce:fb. I use DHCP networking via my wired router.

I just found out that it seems to work better if you remember to disable
networking before you do the suspend. I.e. right click on the applet and
deselect 'enable networking'. It automatically reconnects when you wake
up the system.

I'm having the same problem with Network Manager at Gutsy as Olivier. I always get the "no network adapter" message at Network Manager applet, even when I restart the laptop. I can only get NM working if I use the commands Olivier explained before:
sudo /etc/dbus-
sudo /etc/dbus-
[hangs ; i must "sudo killall -9 NetworkManager", kill -15 doesn't work]
sudo /etc/dbus-

When I resume from suspend2ram, WiFi connectivity is always lost and sometime networkmanager crashes.
I up the interface eth1(my wifi device) from ifconfig And try "iwlist scan" but it claims eth1 does not support scanning.
I have wifi device Intel Corporation PRO/Wireless 3945ABG Network Connection.
I haven't tested wired network yet.

So restarting network manager helps? Isn't NetworkManager restarted for you when resuming from suspend?

I don't know how to restart Networkmanager propably, but i tried a
/etc/init.
I don't think it's restarted. But anyways Andy Baxter sent me a workaround
that actually works. If you disable Networking from nm-applet before
suspend, and re-enable it on resume, all connectivity is resumed.
I do

Hi,
just to confirm that disabling networking in NM-applet before suspend, and re-enabling it after resume does perfectly the job and completely solves the problem for me (tested 3 times), wired or not. Still annoying to have to do this, and other machines (thinking of my old IBM T40p) worked without this. Isn't there a way (a /etc/power or /etc/acpi script) to do this automatically on suspend/resume ?

we have seen improvements in this area. I know that some chipsets still have this issue, so If you still see it, please open a _new_ bug, note your chipset and refer to this bug in your bugreport.
Thanks,

I'm marking this as 'Invalid' against the linux-source-2.6.20 package as this bug really applies to the network-manager package and has been marked 'Fix Released' accordingly. Thanks!

Thanks to everyone for all the info. I'm a bit confused about this issue being marked "Fix Released" though. Alexander Sack wrote (https:/
I still have this problem, too, occasionally, with the same chipset, WIRED Ethernet card: Intel Corporation, Device: 82562ET/EZ/GT/GZ - PRO/100 VE (LOM). Network device: eth0, Hardware address: 00:13:20:0e:ce:fb. I use DHCP networking via my wired router. I still have the same version of Ubuntu (Feisty) as before. Update Manager has so far failed in to upgrade to Gutsy, but that's -- hopefully -- a different issue.
Getting back to network manager, should I open a new bug for the same problem? --Or is Feisty not supported anymore at all now that Gutsy is out, regardless of people who have not been able to upgrade? Thanks in advance for clarifying the process.

Hi Ohb01,
As detailed in the activity log:
https:/
This bug was marked 'Fixed Released' by Alexander back on Oct 4, 2007. As he mentioned, if you are still seeing issues, please open a new bug noting your chipset and reference this bug.
Feisty is still supported, however I'm not sure a fix for this bug would meet the criteria for a stable release update. To find out more information regarding the stable release update process please refer to:

Since the 7.10 Gutsy Gibbon has been released it would be good to know if this is still an issue in the new release. This can be done with the live environment of the Desktop CD. If you could download and try the new version of Ubuntu from http://

I installed Gutsy today on my Dell Inspiron 6400 with the broadcom wireless ethernet. I suspended the session and on resuming the session all interfaces had been lost. This is the first time I have attempted this in Gutsy and I had to use the work around as Olivier. Thanks for the advice Olivier btw.
Details for my card are:
BCM94311MCG wlan mini-PCI
On a full reboot all works ok but not when coming back from suspend.
Guys, we really need some action on this. This is one of the few things that really makes this difficult to 'sell' the average user. I mean I can't see my Dad running some command line code to fix this.
Other than the odd error here and there I am totally sold on this update.
Keep up the good work...
Thanks for your report. Based on the path you list, it doesn't sound like you were running the Ubuntu network-manager. Can you confirm the problems with the stock network-manager?
