ASUS U56 no wifi since 11.10. Known bug. Fix in the works?

Can you give the output of:

sudo lshw -C network; lsb_release -a; uname -a; sudo rfkill list; dmesg | grep -i firm

Thanks

Note that your link is broken..

There is no link, its a command...

I am sorry, try this one.

I am using the 2.6.38 Kernel because it is the last kernel that worked with wifi.

The newest Kernel that I can boot into is 3.015 or something like that.

Thanks,
Ernie

All of the above commands were pasted using the 2.6 kernel. I do not know if this would make a difference, because I am using the 2.6 kernel right now. I can log into the newest kernel and run the commands again if you would like.

Thanks,

See this (I marked your bug as duplicate of this since it has the upstream bug link)
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/876147

I'll save you the reading and give you the "short" version. Use these two commands and your wireless should work:

sudo modprobe -r iwlagn
sudo modprobe iwlagn bt_coex_active=0

If the above worked, then you can make it permanent by adding a file (named iwl.conf) to /etc/modprobe.d/ with the following line as its contents:
options iwlagn bt_coex_active=0

YES!!!!!! It worked!!!!!!!!!!!!!!!

When I log off, do I need to do this command again?

Now, do I need to make this permanent? If so, how do I do that?

Thank you very much. I have been dealing with this problem since I did a clean install and upgraded to 11.10. What confused me was the fact that the wifi worked so well in 11.04!!

Thank you again,
Ernie

It will work until you reboot. To make permanent, use this command to create a new file:
gksu gedit /etc/modprobe.conf/iwl.conf

Copy/Paste this line into the blank file:
options iwlagn bt_coex_active=0

Save. Quit. Enjoy.

Sorry Dave,
I am using Xubuntu, if this helps, but I do not know how to do what you are asking. I am thinking about installing Ubuntu 12.04 over Xubuntu, as the issues that I did not like about 11.10 have been addressed. I rather like 12.04, a lot!!

I have seen gedit before, but never used it. Can you give me a step by step on how to do this. And if I do upgrade to 12.04, it has the newer kernel does the commands change?

Thanks,
Ernie

I can't make it any simpler than this. Run this command (it appears you know how to run commands):

echo "options iwlagn bt_coex_active=0" | sudo tee -a /etc/modprobe.d/iwl.conf

Thank you Dave,
This makes it permanent?

Can I run the same command with I upgrade to 12.04 or do I need to change the iwlagn to something else?

Thank you again!!!!!!!

Thanks Dave Lentz, that solved my question.
