Where do I find wireless drivers the Haswell/Ubuntu XPS 13?
I have one the new Haswell XPS 13's with Ubuntu pre-installed.
Everything seemed to work out of the box, but I wanted a dedicated /home partition. I tried to simply re-partition the pre-installed system, but couldn't boot after that, so I started over with the Sputnik ISO.
That worked, except wireless doesn't work now.
I had remembered that the original kernel was 3.8.0, so I updated the kernel to a 3.8.0 kernel that was available for Precise. Still not luck with wireless.
The original install also had a "Dell Drivers" application, which was not present on the Sputnik install.
What driver do I need for the Haswell XPS 13 wireless card, and where do I find it?
( I did preserve the sda2 recovery partition, but I can't find a "Dell Drivers" application on it. )
Thanks,
Mark

I found this page, which details the hardware in the system:
http://www.ubuntu.com/certification/hardware/201309-14238/components/
It says that the wireless in the system is "Intel Wireless 7260".
This bug report says it's a known issue that the wireless card doesn't work with 12.04.3, and that the recommended fix is to upgrade to 3.11 kernel:
https://bugs.launchpad.net/ubuntu/+source/linux-lts-raring/+bug/1251558
However, I upgraded my kernel from 3.8 to 3.11.10, rebooted, checked "uname -a" to verify, but wireless still don't work.
What further changes do I need to make to get this to work?

I got the wireless working, although it seemed far harder that it should be be for a laptop that's supposed to have great Linux support.
The summary is that for the 3.11 kernel, I needed to acquire "iwlwifi-7260-7.ucode" and copy it to /lib/firmware/
I found the file here: http://wireless.kernel.org/en/users/Drivers/iwlwifi
Direct link to tar.gz file which contains the file was: http://wireless.kernel.org/en/users/Drivers/iwlwifi?action=AttachFile&do=get&target=iwlwifi-7260-ucode-22.1.7.0.tgz
After rebooting, I still had to Disable Networking, then re-enable Networking, then I could enable wireless.

Another option is to use the built-in tool to create official Dell Recovery Media, and use the start-from-scratch approach. The installation from the official recovery media will restore working wireless drivers.
