Wireless issues with an Asus N76VZ / Ubuntu 12.04/Kernel 3.4/Intel Wireless-N 2230
Hi everyone, fairly new to Linux. I've installed Ubuntu 12.04 on my Asus N76VZ, and I'm having issues with the wireless connection dropping every few minutes. I can disconnect and reconnect and it will then work again.
I've already tried disabling IPV6, but that doesn't seem to do anything for me.

Let's try a driver parameter. Please do:
Code:
sudo modprobe -r iwlwifi
sudo modprobe iwlwifi 11n_disable=1
If it helps, we'll write one quick file and make it persistent.

This seems to have helped! How do I make that permanent?

Please do:
Code:
sudo gedit /etc/modprobe.d/iwlwifi.conf
A new, empty file will open. Use kate or leafpad or any text editor if you don't have gedit. Add a single line:
Code:
options iwlwifi 11n_disable=1
Proofread, save and close the text editor. You should be all set.
So the searchers can find the answer, please use thread tools at the top to mark Solved.
Have fun!

Ok scratch that, nope it doesn't seem to work. Connection still drops frequently. Seems to be a random thing, doesn't follow any pattern..
Any other suggestions?
Re: Wireless issues with an Asus N76VZ / Ubuntu 12.04/Kernel 3.4/Intel Wireless-N 223
You might try a different parameter:
Code:
sudo gedit /etc/modprobe.d/iwlwifi.conf
Change the contents to:
Code:
options iwlwifi 11n_disable=1 bt_coex_active=N
Proofread, save and close the text editor. Reboot and let us have your report.

I also just bought an Asus N76VZ V2G today.
Have had it for only 4 hours, and already have the same problem with the wireless network...
REALLY anoying... And I've tried to disable it in the powersafe mode, but nothing makes a difference...
I would give anything for a solution, since the computer is sooooo nice in every other way. But this is kind of important to get fixed... Seems like it might be a problem with this specifik model. But it's gotta be possible to solve it somehow, right ?

What is your experience after the solution I proposed above?
Re: Wireless issues with an Asus N76VZ / Ubuntu 12.04/Kernel 3.4/Intel Wireless-N 223
I havn't tried your solution yet.
I've ready that Intel in generel have major problems with many of their network cards.
I assume that is the same problem in this case.
My network card is an Intel Centrino Wireless-N 2230.
Therefore I will try to look for some driver updates.
If that doesn't work, I might give your solution a try :)

Hmm nope, that isn't working either. Connection still dropping really often.
@Asus User: If you manage to make it work, please post your solution here as well! This problem is making it really hard for me to work with ubuntu.
