Wireless issues with an Asus N76VZ / Ubuntu 12.04/Kernel 3.4/Intel Wireless-N 2230

[benTheLightman]

Got exactly the same problem with the Asus N56vz with the Intel centrino 2230 wireless card. It seems to only occur on N-networks. Have no problems at all with my home G-network.

The fix didn't work either... still disconnects every few minutes

Let's try a driver parameter. Please do:

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

If it helps, we'll write one quick file and make it persistent.

It worked for me!

That worked for me, too!

Great, thank you!

this seems to be a persistent problem with all intel Centrino variants, i have option of ditching my Centrino and using Killer's Bigfoot Wireless instead, are there similar issues with that particular wifi card?

Additionally after a kernel update sometimes the problem comes back and becomes persistent regardless of what solution may have worked in the past.

The Bigfoot wireless I am familiar with uses the driver ath9k. Search this forum and see if there are ever any disconnects and drops or slow speeds with ath9k. Here, for example: http://ubuntuforums.org/showthread.p...ighlight=ath9k

Have you tried turning N speeds off at the router? My iwlwifi device is about perfect.

Please do:

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:

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!
