View Full Version : [SOLVED] 11.04 - wifi causing computer to freeze

I'm writing this all on a phone so hang with me, k.

I'm using an Asus Eee PC and my wireless card is an Atheros AR2427; I have never had any issues with wireless on 10.10, everything worked out of the box. Installing the upgrade was not a problem but when I restarted and my wireless tried to connect it automatically froze. Everything. All of it. Like I've seen plenty of others having trouble with wireless on natty but not to the extent I'm experiencing. Before it crashed I could see a list of networks and I'm p sure that the crash occurs the moment I am connected to the network. It does this regardless of the network I try to connect to, btw.

I went in to BIOS and disabled my wireless, logged back in and as far as I can tell everything else is fine. I assume wired internet would work too, however, my wifi is provided by the building I live in and unless I want to bother my strange, irate landlord wireless (and my phone :B) is the only internet I have access to. Which I now can't use soooo is there anything I can do about this without having to connect to the internet?

Editing to add that I tracked down someone to let me use their ethernet and it works fine. Still the same problem with wireless.

Same Problem here! I have an eee pc r101 with an AR2427 wireless network adapter. After upgrading to 11.04 the system freezes when the wifi connection establishes.

This issue seems to be reported as a bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/735431

Edit: Found another thread that fixed the problem. http://ubuntuforums.org/showthread.php?p=10750214#post10750214

Thanks so much! abelmaio's solution worked like a charm. I actually had found the ppa last night and downloaded it but I was previously clueless as to how to get it working, hahaha.

the problem is with the kernel in 11.04, seems to include all newer asus eeepc's and is solved in latest kernel.
to solve that you can download the latest kernel and install it very easily;
go to
http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/
and download the files;

linux-headers-2.6.39-999_2.6.39-999.201105191210_all.deb
linux-headers-2.6.39-999-generic_2.6.39-999.201105191210_i386.deb
linux-image-2.6.39-999-generic_2.6.39-999.201105191210_i386.deb

(or different versions depending on time) then install them in exactly same order by the command;

sudo dpkg -i filename

one after the other, then restart the netbook. it worked perfectly for me.
