Description of problem: At seemingly random intervals, my wireless connection stops working (though NetworkManager shows I am still connected). % lspci | grep Centrino 03:00.0 Network controller: Intel Corporation Centrino Ultimate-N 6300 (rev 3e) This is what I see in dmesg when the problem happens: [ 4072.821675] iwlwifi 0000:03:00.0: Queue 2 stuck for 2000 ms.

Version-Release number of selected component (if applicable): kernel-3.2.10-3.fc16.x86_64 How reproducible: Generally within fifteen minutes of booting. Steps to Reproduce: 1. Connect to the wireless network. 2. Do anything which causes traffic. Actual results: Wireless flakes out. Expected results: Wireless should keep working. Additional info: This bug is presumably not the same as the one solved when Bug 785239 was closed, as many commenters there still have a problem. I've opened this bug so that there is an open bug to catch those problem reports.
Thanks for opening a new bug. Hopefully that will isolate attention to the specific problem you are experiencing.
Currently firmware restart is broken, perhaps firmware will recover itself without restart, try wd_disable=1 module option. If it will not help, please check if this is 11n issue, by run driver with 11n_disable=1 option
I tried wd_disable=1 on the current boot. It makes no difference that I can see. I'll try 11n_disable=1 the next time I boot.
Apparently there should be no "Queue stuck" messages with wd_disable=1, device can still malfunction of course.
From dmesg: [ 0.000000] Command line: BOOT_IMAGE=/vmlinuz-3.2.10-3.fc16.x86_64 root=/dev/mapper/vg_scylla-lv_root ro quiet rhgb SYSFONT=latarcyrheb-sun16 LANG=en_US.UTF-8 KEYTABLE=us wd_disable=1 When the connection went bad: [ 480.454781] iwlwifi 0000:03:00.0: Queue 2 stuck for 2000 ms.

If you want pass module parameter through kernel command line, module name should be specified i.e: iwlwifi.wd_disable=1 Note: you do not have to reboot to test module parameter, it can be done on run-time, like in example: modprobe -r iwlwifi modprobe iwlwifi wd_disable=1

I was experiencing bug 785239 before, but it was much more severe. This bug only manifest itself after uptime of hours while the old one was allowing the wlan connection to last mere minutes. I have a Wireless-N 6320 card here.
(In reply to comment #6) > If you want pass module parameter through kernel command line, module name > should be specified i.e: iwlwifi.wd_disable=1 Aha, I thought it was a kernel parameter, not a module parameter. Thanks. > Note: you do not have to reboot to test module parameter, it can be done on > run-time, like in example: > > modprobe -r iwlwifi > modprobe iwlwifi wd_disable=1 When I do this, it causes a different problem: It appears to crash the NetworkManager applet, and then when I restart the NM applet, the interface won't come back up: [22467.238996] udevd[29403]: renamed network interface wlan0 to wlan1 [22543.139892] iwlwifi 0000:03:00.0: L1 Enabled; Disabling L0S [22543.140098] iwlwifi 0000:03:00.0: Radio type=0x0-0x3-0x1 [22543.378661] iwlwifi 0000:03:00.0: L1 Enabled; Disabling L0S [22543.378866] iwlwifi 0000:03:00.0: Radio type=0x0-0x3-0x1 [22543.497744] ADDRCONF(NETDEV_UP): wlan1: link is not ready It seems like specifying the parameter it at boot time is a more reliable way for me to test, for the moment. I've been running for an hour and a half now with iwlwifi.wd_disable=1 without any connection problems, so this is promising.
I've now run for 6:30 using iwlwifi.wd_disable=1 without issue.
[mass update] kernel-3.3.0-4.fc16 has been pushed to the Fedora 16 stable repository. Please retest with this update.

Looks like I spoke too soon. After approx. 2 and a half hours of uptime problem has hit again: [ 8776.800424] iwlwifi 0000:04:00.0: Queue 12 stuck for 10000 ms.

I still get stuck queues with kernel-3.3.0-4.fc16.x86_64 when not using iwlwifi.wd_disable=1. [ 966.188053] iwlwifi 0000:03:00.0: Queue 2 stuck for 2000 ms.

That is firmware problem or driver do not talk nicely to firmware. Driver internal watchdog check for that issues, and reset firmware if error occurs, but since currently firmware reset is broken we are not able to recover.
Does this mean you have the information you asked for or should we run more tests?
No new information is needed from You. I reported problem to Intel, I'm waiting for they fix.

Yet another bug, seems 3.2 -> 3.3 regression on mac80211, please open a different report for it. Regulatory domain is set based on timezone, do you have correct zone in /etc/sysconfig/clock ?

I am in the United States and am having the same original issue. Wireless shows connected and ok and no errors. It just crashes Network Manager. Can't hit any ips including my router its connected to. I simply disable the wireless and reenable and this resolves the issue for a while. Really need to get a quick fix on this and it should be a sev 1 ticket as this is major bug that causes me to loose my virtual box connections. Below is my snippit from the messages log when this issue occurs.

I did't get any answer about that for long time. Finally I opened a bug report on their bugzilla to track the problem: http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2359 They confirm there, that the bug is reproducible and they will debug it.
There is a proposed patch at http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2359 I tried applying it, but it doesn't match the sources in kernel-3.4.0-1.fc17.src.rpm and frankly the source in http://git.kernel.org/?p=linux/kernel/git/iwlwifi is sufficiently different to mine that I'm not sure how I would go ahead. But if someone with more kernel patching knowledge than me could give the patch a spin, that would be great!

I also get this, though with fedora 17.
I seem to be experiencing right the same issue, although only on some networks, and wd_disable=1 and 11n_disable=1 seem to help getting rid of it...
# Mass update to all open bugs. Kernel 3.6.2-1.fc16 has just been pushed to updates. This update is a significant rebase from the previous version.

I haven't been having this problem with 3.6.3-1.fc17.x86_64, which is a bit newer than the kernel asked about above.
