Do you still have a config file to remove "N" from card.
gksudo gedit /etc/modprobe.d/iwlagn.conf
Comment the one line out "#" sign in front of line. (without quotes)
and reboot will put "N" back in card functions.
3.0 and up works with iwlagn driver by intel in N.
Do not know if that will fix your problem but should fix the config file anyway.
Re: Can't connect to wireless after 11.10 upgrade
Hi garvinrick4, is this what you are talking about?
Code:
sudo ifconfig wlan0 down
sudo rmmod -f iwlagn
sudo modprobe iwlagn 11n_disable=1
sudo ifconfig wlan0 up
To the client please try this code one line at a time and if it works we will need to make it permanent.
Thank you

I believe he has a the N disabled and does not need to be with "iwlagn" driver with
kernel 3.0 and up.
Going around for a while was to just make a config file and place the line
options iwlagn 11n_disable50=1 11n_disable=1
In the config file /etc/modprobe.d/iwlagn.conf that user made. (I noticed the his card said 802.11 bg) And it is an N card.
#You take over this thread wildmanne39 you are better with Network cards and their drives than I. I can do a little bcm cards and iwlagn driver for intel's.
Re: Can't connect to wireless after 11.10 upgrade
Hi, you are correct that is the way to make it permanent,and it has been needed since upgrading to kernel 3.0.
You are doing fine.
I too struggle with some issues.
Re: Can't connect to wireless after 11.10 upgrade
yes thank you. i did fix the config file and have not changed the post. Still doesn't affect wireless connectivity but good catch

I got this message for the last command
jupiter@jupiter-U56E:~$ sudo ifconfig iwlagn up
iwlagn: ERROR while getting interface flags: No such device
how do I re-enable n?
Re: Can't connect to wireless after 11.10 upgrade
Hi, did you run this command one line at a time? Make sure you disconnect your wired connection first and do not restart your computer after you run the commands.
Code:
sudo ifconfig wlan0 down
sudo rmmod -f iwlagn
sudo modprobe iwlagn 11n_disable=1
sudo ifconfig wlan0 up
If this does not work let us know and we will go from there.
Thank you
Re: Can't connect to wireless after 11.10 upgrade
Hi, I had a typo in the last command, I fixed it, now run the commands again please.
Thank you

Typo post 5, should be:
it has not been needed since upgrading to kernel 3.0
"N" in 'iwlagn" will work in 3.0 and up kernels.
If you owned a "g'' router never new was a problem with "iwlagn",
If you owned a "N" router had to remove "N" with config file from card. "iwlagn" driver would depreciate to not working at all without config file. (11.04 and down)
Or install a kernel of 3.0 and up. (maverick and Natty) with upgrade in module-init-tools both links below to .deb files.
http://kernel.ubuntu.com/~kernel-ppa/mainline/
https://launchpad.net/ubuntu/+source.../3.13-1ubuntu1
It is my driver, you get to no em like the back of your hand.
Some users that upgraded still have config file in /etc/modprobe.d/iwlagn.conf and should be removed to work with N in 3.0 and up.
