Hi Hossein,
Sorry for taking so long coming back to you. I was able to reproduce
this issue (got a laptop with similar wireless card), and I believe I
found the commit that fixes it:

Aparentely, the issue is caused by an ove
I have attached full syslog and kern.log files as well as the
errors/warnings generated after switching wifi speed to 11 Mbps. Please
let me know if there is anything I can do to help.

OK, I think I have narrowed it down. It seems that the problem exists in
"v3.3.8-quantal" while it is fixed in "v3.4-rc1-precise" and "v3.4-precise". So
I think any commit that fixed it should have been bewteen these two versions.
Even in the fixed kernels there are some messages(warnings/errors)
Hi Hossein, so the next step is to try to find out the last "bad" kernel
and the first "good" kernel. To do this, please go:
http://kernel.ubuntu.com/~kernel-ppa/mainline/
(don't forget to uninstall tested kernels, otherwise you'll fill up your
disk :) )
You can start v3.5-quantal, v3.5-rc7-qua
Thank you Luis. I just tried your kernel. The problem still exists and
changing too 11Mbps causes a system freeze in seconds. If there is
anything else I can do, just let me know.
Thanks for your support.

I took a look at recent modifications to the iwlwifi driver and there
was one commit that caught my attention:

Thanks for the instructions. I tried kernel 3.6-rc1-quantal and it DOES
fix the problem. At least for the 4-5 times that I tried, it did not
cause any system freezes, while the normal kernel 3.2.0-29 freezes
within a few seconds. If there is anything I can do, let me know.

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v3.5kernel[0] (Not a kernel in the daily directory) and install both the
linux-image and linux-image-extra .deb packages.
Once you've tested the upstream
I opened a terminal running "tail -f /var/log/kern.log" while switching
to 11Mbps speed. I received the following message before going into

the first one, I could not record all of them):
