Bug Description

Binary package hint: wpasupplicant

I am no longer able to connect to wifi N networks since updates in the last couple of days. Switching the router back into G mode and I can connect fine.

Running Maverick, installed about 1 week ago and completely up to date. Wifi was working fine up until about about 1-2 days ago.

below are the messages from the syslog.

This is actually a kernel bug in linux-image-2.6.35-22-generic

Wifi N works fine, when I boot using older 2.6.32 kernel

Wireless was working OK until I had updated the distro.

I have the same problem with intel 4965 chipset, it appeared within last couple of days. Really annoying, as i cant change the router to G mode and have to use a wired connection on my laptop now

Everything works fine in 10.04. It looks like a regression.

The problem persists with wpasupplicant v0.7.3 from ppa.

I'm also experiencing the same error.

I can use wifi G secured with WPA2 Personal, so I don't know if this has nothing to do with wpasupplicant, unless the algorithm to authenticate the N and the G networks for WPA2 Personal is different.

For me, updating wpasupplicant didn't work. I also updated the kernel version to 2.6.36rc7, no luck.

Now I'm using 2.6.36rc7 with wpasupplicant 0.7.2 and NetworkManager 0.8.1+git.20100810t184654.ab580f4-0ubuntu2.

It is very impressive to see this kind of bugs at this late stage in the release cycle. For sure, the final release will have this bug, bothering a lot of users.

You developers think about it.

looks like it has been disabled on purpose to fix another bug perhaps?

/etc/modprobe.d/intel-5300-iwlagn-disable11n.conf

Some talk about things here suggest there is a intel firmware issue on
2.6.35 causing instability.

just to confirm that after editing that file in my last post and set to
0. can connect to wifi N again.

Now lets see if its stable ;)

Definitely appears to be some underlying issues with the current iwlagn drivers and/or firmware.

While I haven't had any drop-outs, performance is miserable at ~5mbps.

In my case, after editing intel-5300-iwlagn-disable11n.conf the system performs without problems and performance is OK. I have an Intel 5100 WLAN Card.

Hi Tim,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the 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.

Thanks in advance.

It also happens with an Intel Wifi Link 4965abgn, both on Linux and Windows, so maybe the router's firmware is also based on Kernel Linux 2.6.35?

Hi,
I have updated to latest kernel (uname -a => Linux eeepc 2.6.36-020636-generic #201010210905 SMP Thu Oct 21 10:17:53 UTC 2010 i686 GNU/Linux) and it still can't connect to my wifi N network.

Tim Lunn (darkxst) wrote :

I tested with the lastest .35 mainline kernel and it seemed to be ok, a little slow, but definitely usable.

Now just switched back to the normal kernel and it still seems ok.

Getting around 70mbps, although used to get around 100mbps previously on Lucid.

Filiprino see comment #8 above.

Atleast for the intel wifi card, N has been disabled by default.

Filiprino (filiprino) wrote :

Hi Tim,

But it also happens with the Atheros on my netbook, and the Intel wifi card has the same issue on Windows (router denies association) :S

Filiprino (filiprino) wrote :

Hi all,
I finally could connect in Wireless N mode. I had to activate Wi-Fi Multimedia on the router, functionallity which is required for 802.11n.

Changed my AP to N only.
Win7 laptop still connected but not my Ubuntu 12.4 Lenovo laptop with
03:00.0 Network controller: Intel Corporation Centrino Advanced-N 6205 (rev 34)

After searching a bit i found this thread, and the note from Filiprino above sorted me out.
Had to switch "WMM(Wi-Fi Multimedia):" from off to auto. Leaving the ap on N only.

Suddenly ubuntu connected using WPA-PSK without any problems.
Even solved the problem for my Android ICS phone's wifi.
