intel 5300agn in Oneric leads Speedport w722v router to crash and reboot

[H.i.M]

While Testing Oneric alpha 3 and connecting via wifi to a router called Speedport w722v Type B the connection leads the router to reboot after sending a few packages. There was no problem in lucid. It is reproducable. The router has the newest firmware 1.18 (12/2010) installed. The router is frequently used in Germany with "Deutsche Telekom"-vdsl-internet-connections.

Could you clarify your report. Oneiric causes the wifi router to crash and reboot ?

[H.i.M (hir-i-mogul-gmail)]

Yes. Crash and then reboot.

[H.i.M (hir-i-mogul-gmail)]

These are similar reports:

There is a kernel patch for fedora 16 available. Could this be migrated to ubuntu?

Thank you for taking the time to file a bug report on this issue.

However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.

We have noted that there is a newer version of the development kernel currently in the release pocket than the one you tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.

If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released.

Thank you for your help.

I cant test this again, cause the router is currently not in my location.

Bug still exists as of Beta 2 of Oneiric. Having similar problem on my ThinkPad x200 with Intel 5300 inside connecting to a Verizon issued Actiontec Wireless N router. Though the router doesn't reboot, just crash -- taking out WiFi, Ethernet, and Internet. Reboot must be performed manually.

Discovered that adding "options iwlagn 11n_disable=1" to /etc/modprobe.d/iwlagn.conf solves the problem.

[Oded Arbel (oded-geek)]

Same here: I'm using Oneiric on ThinkPad T420 with IWL 6205. starting wireless completely crashes my router that runs DD-WRT v24SP2 (it doesn't reboot - it has to be power cycled). After setting "options iwlagn 11n_disable", it works fine.

Currently its not much of an issue as my router is 802.11g, but it would be nice to have this fixed without disabling 802.11n. I'm also trying the kernel patch listed above, but it will take more time for the kernel to finish compiling here :-)

[Oded Arbel (oded-geek)]

After installing the patched kernel and rebooting (without the 11n_disable option), oneiric still crashes my router. Assuming I've built the Ubuntu kernel properly, then the patch is not a solution and the only workaround at the moment is to disable wireless-N.

[Donnie Eldridge (donnieeldridge)]

I'm experiencing the same issue with Ocelot using a Dell Studio 1749 and my Netgear WNDR3700 Router.
I currently have to disable wireless-N. It's a bit disappointing since I had no issues with Natty.

[entonjackson (aj-mysc)]

Same Problem here with dell precisiion m4400 and oneiric 64bit and speedport w 504v

[Vinod (vmukkamala)]

I got a similar problem here. I have a System76 with Intel WiFi Link 5100 AGN. The router is an Actiontec MI424WR-GEN2 version 20.19.8. Upgraded from Natty today afternoon, as soon saw all my network devices disconnected as soon as System76 connected to WiFi router.

[Buster F (evasionoftruth)]

Same issue here with a Intel Ultimate N Wifi Link 5300, worked fine in Natty

[Joseph Salisbury (jsalisbury)]

Do you happen to know if this only happens with wireless protocol N? This may be a duplicate of bug 836250

[make (kaizenceo)]

my solution was, uninstall 'network-manager' and install 'wicd'.

worked great so i never looked back

 will wait for fix somewhere down the line

happy hunting

[Antonio Rivas (antonio-rivas)]

I tried the make (kaizenceo) solution and it doesn't worked to me, so it isn't a general one. I think the reason is in the kernel 3.0, because if I boot using another previous kernel the problem is out.

[MeneM (mark-maas-martin)]

Agreed, I have the same issue with a Lenovo Edge 11, and WNDR3700 v2 with dd-wrt on it.

[Ben (bhubu)]

I can confirm this bug with 11.10 64 bit in conjunction with Speedport W 504v. Router continuously reboots when WLAN is connected.

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . If possible, please test the latest kernel (Not a kernel in the daily directory). Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag(Only that one tag, please leave the others). 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.

If this bug is fixed by the mainline kernel, please add the following tag 'kernel-fixed-upstream-KERNEL-VERSION'. For example, if kernel version 3.1-rc9 fixed and issue, the tag would be: 'kernel-fixed-upstream-v3.1-rc9'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Thanks in advance.

Tested with upstream kernel 3.2 rc1. WLAN driver did not work at all. Additionally graphic driver had major problems (display flickered).

Hardware used: HP EliteBook 2730p

[Ben (bhubu)]

Tested with upstream kernel 3.1.1. WLAN driver did work. Router did not reboot.
For me its still not a solution, because display is still flickering.
But regarding the WLAN 3.1.1 fixes the issue for my router.

[Ben (bhubu)]

Kernel 3.0.0-13 fixed the issue on my notebook. Now WLAN and graphic are working.

[Po-Hsu Lin (cypressyew)]

Closing this bug with Won't fix as this kernel / release is no longer supported.
Please feel free to open a new bug report if you're still experiencing this on a newer release (Bionic 18.04.3 / Disco 19.04)
Thanks!
