iwlagn - Wireless network disconnects and won't reconnect without reboot

[kdawgud]

Binary package hint: network-manager

The wireless connection seems to disconnect about once a day. After this occurs, it won't reconnect to any wireless networks until I reboot. I have been running Jaunty since Alpha 6, but the problem only happened last week (during the release candidate).

Here is the output of events from the syslog. It looks like the wireless network disconnected and tried to reconnect on its own while nobody was using the laptop. I will attach lspci below.

The log starts out with these events:

Apr 22 08:01:52 kleber vmnetBridge: RTM_NEWLINK: name:wlan0 index:4 flags:0x00011043
Apr 22 08:01:52 kleber vmnetBridge: Can't add interface wlan0 4 (does exist).
Apr 22 08:03:51 kleber vmnetBridge: RTM_NEWLINK: name:wlan0 index:4 flags:0x00011043
Apr 22 08:03:51 kleber vmnetBridge: Can't add interface wlan0 4 (does exist).

Seems like the wifi is still working fine while these messages are generated (since they're still being generated now).

Then at 10:30am, I get this event:

[Alexander Sack (asac)]

this is a driver bug. moving to linux package. you could install the linux-backport-modules-jaunty package and see if your problem goes away.

[Martin Emrich (emme)]

I also experience this, and reloading the wireless modules helps usually:

-----
#!/bin/sh

sudo rmmod iwlagn
sudo rmmod iwlcore
sudo rmmod mac80211
sudo rmmod cfg80211

sleep 2

sudo modprobe iwlagn
-----

I just installed the backport modules, and will see if they help with this bug as well as my regular network freezes.

Ciao

With the backport modules, it was even worse, one minute after connecting, the connection stopped working. My syslog is full of these message:

[kdawgud (kleber)]

The backports modules fixed it for me (or I should say it ran for 1 day without seeing the problem - which is more than it had been running).

I will update again in a few days if it still hasn't occurred.

[svaens (svaens)]

I also have this problem.

I am using the cs_orinoco module for my wireless card.

since we are pasting sys logs... mine maybe are interesting

Seeing someone with a fellow problem I felt I must share my findings seeing that I had the same issue, the result for me was to disable VM ware whenever I was not using it. I did this by
sudo /etc/init.d/vmware stop

This instantly reduced my wireless issues with (vmnetBridge) now I have to fix my vmware problem.

For the record I am using -
Ubuntu 9.04 (64bit) Jaunty Jackalope
Wireless card: IPW3945
VMware Workstation 6.5

[jjcobm (jjcobm)]

I also have this problem. My laptop is using an Intel Wifi Link 5100, it disconnects and I cannot reconnect without a reboot. Using Jaunty 32bit.

[svaens (svaens)]

I don't have vmware installed, so it has obviously nothing to do with that.
Just happens in the blue. Or rather, when i have had lots of network
traffic. i.e. using bittorrent.

This bug is currently marked as Incomplete.

As this 'is' a bug, and should be fixed (using backports sounds like a workaround, not a solution), I ask now;

How do i progress this bug, and move it from 'Incomplete' to 'new', and get someone to generally accept it (or even take notice of it) ???

[hatsch (hatsch)]

same problem here on jaunty with Intel Corporation 4965 AGN
network-manager disconnects after some time (lot's of traffic?) most of the time reconnecting works, but sometimes i need to modprobe the driver again....

isn't it just a problem with the firmware?

[svaens (svaens)]

There should be some comment on this bug from the people who would be able to fix it. Please.
I will provide any information they ask for. Please ask.
Seeing as there have been problems with several modules, i wonder if there isn't something else at fault here.

[svaens (svaens)]

by the way, like i think i said before, i'm not using the same modules as the first person who created this bug. And i have similar problems.

more behavioral information:

1. first i start the computer,
2. second, wireless connects
3. use internet, high data usage
4. random amount of time, wireless cuts out
5. attempt to re-connect causes authentication dialog to pop up.
6. re typing the key details results in behavior which seems from outward appearances the same as if i had typed in the wrong authentication key.

No amount of attempts allows me to reconnect. Only a reboot fixes it.

If you could also test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine this issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

If the issue remains with the upstream kernel, please be sure to also run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

Hello all,

I'm using Jaunty on Samsung NC10 and I installed linux-backport-modules-jaunty. Now I've been using Ubuntu for few days w/o major networking problems. WPA2 occassionally fails with some routers, but that's an another issue. I'd like to add that before installing backport modules I had to boot to Win XP in order to get the network adapter functional again. I don't know the actual reason for that, but it seems to be related in some power saving function because it usually occurred after an S3 sleep state. I don't know if the linux-backport-modules-jaunty resolved this issue for me, but it's surely looking good right now .

[José Valecillos (j-valecillos)]

It's the same problem with ath5k and seem that happen with many others wireless cards. Isn't a Ubuntu problem, in Archlinux i have the problem too.

The problem is easily reproducible:
You connect to a network, then disconnect, and finally, try to connecting again. Wicd just say: "Unable to obtain IP Address"

There is a workaround (rough-and-ready) if you reload the kernel module of the wireless interface with rmmod (or modprobe -r, it's the same) and then modprobe. This is the reason because many of you have to reboot the computer, but just need reload the module.

In the bugtracker of Archlinux (http://bugs.archlinux.org/task/18011) they say that is a kernel problem, i don't know. But that i know is that other networks manager don't have this problem just with wicd.

[sahas (napster-it)]

I experience the same problem with my Ubuntu install.
My system specs:
HP dv5t laptop with Intel 5100 network card
Ubuntu Karmic

Rebooting or reloading the network modules does the trick for me but it still is very irritating...
Curiously, hard stop and start of wireless radio receiver (via the touch button on top of the keyboard) does not work. When I swipe that button, instead of the light turning red (which should be the case), it starts to blink! Looking into that, which I will later, should help pinpoint the nature of the problem.

P.S. : I just reloaded my network modules in order to submit this :D

Seems to be the same (or at least same symptoms) that I see on karmic amd64 running 2.6.31-17-generic with "Intel Corporation Wireless WiFi Link 5300" (thinkpad x200s). I can get it unstuck by flipping the wireless hw kill switch to turn wireless off and then on again after a few seconds.

When broken the lines:

Hi!
Can you try this solution:

Add pci=use_crs at the end of the line

linux /boot/vmlinuz-2.6.31-19-generic root=UUID=8a7ca0ae-ec6e-4df9-9661-edccf300d223 ro quiet splash

in the file /boot/grub/grub.cfg and reboot.

I have now this bug with openSUSE 11.2 too. pci=usr-crs don't solve the problem. Any ideas?

I suspect this problem might have some relation to Bug #352228

I would defiantly say it is related every one should comment and post on that bug since it actually has a Kernel person assigned to the bug. There are quiet a few bug reports for this core issue but that one is the first time I have seen someone assigned to it.

My problem is with Intel driver so I think the other bug is the one valid to me. If everyone agrees, then we should mark this as a duplicate of https://bugs.launchpad.net/bugs/352228
