Centrino Wireless-N + WiMAX 6150 recognizes Wifi but doesn't connect

[42th]

So I've installed Ubuntu 12.04 LTS on my laptop that uses a Centrino Wireless-N + WiMAX 6150. I try to connect to my college campus wifi, which it recognizes, but whenever I put in my login information, it attempts to connect for a while before it spits out the "Wireless Network Authentication Required" screen before it finally disconnects from the wireless. It does this ad nauseum. I am able to get a wired connection, which is what I am currently using right now.

I did try to do my homework on this, which ultimately lead me here. I've been to http://intellinuxwireless.org/?n=Info to make sure my drivers up to date, and then I found out that since I'm using 12.04, all the drivers should have been up to date anyway. I also found out that kernels later than 2.6.38 are broken with the Centrino Wireless-N + WiMAX 6150 wireless cards, but since this was a fresh install of Ubuntu and not an upgrade, I didn't think this was a feasible option and that it really apply to me. So, I'm currently at a loss.

Also, after poking around the forums for a bit, here are my outputs of the following:

cat /etc/lsb-release; uname -a 
lspci -nnk | grep -iA2 net 
lsusb 
iwconfig 
rfkill list all 
lsmod

Bump. I need some help please and thanks.

[chili555]

Just to humor an old driver dawg, please try:

sudo modprobe -r iwlwifi
sudo modprobe iwlwifi 11n_disable=1

Any improvement? If so, we'll write a quick file to make it persistent.

[wildmanne39]

Hi, I can tell you things that usually keeps that driver from connecting but it gets harder to fix certain issues when a college comes into play, because it may require changing router settings and such but we will start with the basics.

Does it connect at home?
Please do:

echo "blacklist asus_wmi" | sudo tee -a /etc/modprobe.d/blacklist.conf

echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
sudo modprobe -rfv iwlwifi
sudo modprobe -v iwlwifi

does it connect know? if not post the output of:

nm-tool
sudo cat /var/log/syslog | grep -e iwl -e firmware -e wpa -e wlan -e etork | tail -n55

Thanks

I'm apologize, I forgot to mention that I can't connect to any wireless. I've tried with my home wifi, my friend's wifi, and my campus's wifi and had no such luck.

Please do:

echo "blacklist asus_wmi" | sudo tee -a /etc/modprobe.d/blacklist.conf

echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
sudo modprobe -rfv iwlwifi
sudo modprobe -v iwlwifi

When I did this:

sudo modprobe -v iwlwifi

I got this error message:

Hi, I did not see chili555 there when I posted we must have been posting at the same time, I will let him handle this since he was here first and he is the best at these issues.

[chili555]

Haha! I'm not at all sure I know any more than the Wild Man. Please post:

cat /etc/modprobe.d/iwlwifi.conf

If it says anything different than:

options iwlwifi 11n_disable=1

...then you'll net to edit the file to make it so:

sudo gedit /etc/modprobe.d/iwlwifi.conf

Amend, proofread and save. Close gedit. Now do:

sudo modprobe -r iwlwifi
sudo modprobe iwlwifi

Any errors, warnings, smoke or sparks? Thanks.

When I did this:

[chili555]

Unknown symbol in module, or unknown parameter (see dmesg)

Let's see dmesg then:

sudo modprobe iwlwifi
dmesg | grep iwl

Thanks.

[42th]

My iwlwifi.conf is correct now; '1' and 'l' look similar enough that I didn't notice any difference. Sorry about that...

but I was able to successfully do:

sudo modprobe iwlwifi

without any errors.

I'm currently testing on my home wifi now. It recognizes my home wifi and attempts to connect.
After the Wireless Network Authentication Required screen pops, I enter in my password and it tries to connect for a few minutes before the authentication screen pops up again.
