Broadcom 4322 extremly slow with wl.ko

[Fridtjof Busse]

I'm using a notebook with a Broadcom BCM4322, which is correctly set up with the non-free wl.ko module on jaunty (2.6.28-14.47-generic).
However, this driver exhibits a very weird behavior: Although the WLAN-link (WPA2 with AES, but TKIP has the same problem) is stable, loading a website sometimes simply stalls, only a reload works. Downloads are, once started, as fast as my downstream.
There is nothing in dmesg or syslog, but it happens with every website. Sometimes they load immediatly, sometimes they simply don't. Via ethernet, there is no problem.
Any way to debug this further?

Forgot to mention: In tcpdump, I see packets going to the webserver, but there is simply no answer.

I experience the same problem with karmic, even with WPA2-PSK disabled.
Is there maybe some sort of power-management that causes this problem? Still nothing in the logs, and as ndiswrapper crashes on karmic, I cannot test the alternative.

'iwconfig eth1 power off' does indeed seem to fix this particular problem.
Is this a known problem with nowadays WLAN cards?

I have the same issue (inspiron mini 10v) and can confirm that 'iwconfig eth1 power off' appears to fix the issue.

This bug was reported against the linux-meta package when it likely should have been reported against the linux package instead. We are automatically transitioning this to the linux kernel package so that the appropriate teams are notified and made aware of this issue.

If this bug really is a bug in the linux-meta package you can move it back to linux-meta and set the Status to Confirmed, or contact us on the #ubuntu-kernel channel on the FreeNode IRC server. Thanks.

Hi Fridtjof,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 412838

Also, if you could 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.

On lucid, I get only very few connetion interrupts, no need for the iwconfig-workaround. Seems to be fixed.
