Centrino wireless: good results with kernel 3.4 from experimental repo
Concerning Debian Squeeze/Wheezy wireless:
I have Dell Precision M4600 and have had a lot of trouble connecting
to wireless networks. I was constantly failing to join networks, as
described https://bugzilla.gnome.org/show_bug.cgi?id=676382 and on
other bug trackers. Here's my blog about it
But it appears good now. Following instructions at
http://wiki.debian.org/DebianExperimental, I got a working 3.4
linux-image. And the wireless performance driver is much better! I'm
not able to confirm or deny claims that the speed of transmission is
slower or faster than it ought to be with 3.4, but I can say honestly
that the ability to associate with routers is much much better.
The best part is that the install is easy, it does not require the
changes to any other packages. The new kernel is a boot-time option
(grub), and if you don't like it, you are not stuck with it. But I
bet you will like it.
It is this easy. Create this file.
$ cat /etc/apt/sources.list.d/experimental.list
deb http://ftp.debian.org/debian experimental main
$ sudo apt-get update
>From there I only installed
Linux 3.4 for 64-bit PCs
All header files for Linux 3.4 (meta-package)
Kbuild infrastructure for Linux 3.4
My system has nvidia proprietary drivers and a few other components
set up as kernel modules with dkms. All of those were updated
automatically, everything "just worked".
