The above command failed on my (stock) Dell XPS 13 Developer Edition, due to unmet dependencies.
However, after some great help from the folks on the #ubuntu-uk IRC channel, here's a solution that worked from my LX322x machine (fitted with the Atheros wireless card:
Open a terminal (press CTRL+ALT+T) and type: sudo apt-get install linux-generic-lts-quantal
Then reboot your laptop.
This command installs a newer Linux kernel, with better drivers for the wifi card. I can confirm that all the other features (hotkeys, two finger scrolling etc.) all continue to work on this kernel.
After months of attempting to fix this issue, installing this backport worked for me using the provided instructions.
The new drivers should then be in use, but note you will need to do the steps 4-7 again if a Linux kernel update comes as a security update or otherwise.
I just had time to use my new XPS 13 and found out also the disconnecting WiFi issue 😞
I updated to the new kernel as mentioned previously in this topic (quantal) and hope that will help. I have not tried it yet.
The machine cost me 1200 euro's which I paid to get a full functioning device. The Wifi issue is quite old now and people are able to fix it using some sort of update.
@Barton_George what will be the solution from Dell on this? If I reinstall my system again, I just want to update it and then work.
What support is there fore 13.04 / 13.10 / 14.04 ?
I also have this issue (my logs look exactly what poster #1 posts) and am also disappointed that this product (which is marketed as an out-of-the-box functional, tested product) has such a critical problem that I think should have been spotted and addressed in QA. I would like to have an answer from a Dell representative about the steps to address this issue. I have seen at least:
- have ProSupport replace Atheros network card by Intel.
- downgrade some server module to an older version
- upgrade to a kernel module
Since the product is sold with Dell ProSupport, I called them in my country (Netherlands) and asked them for an answer. Disappointingly, they say the only support for this product is via this Forum as they have no Linux expertise. I told them that this product is sold with Linux and claims to include support with no success. (They are willing to send someone to replace the network card).
Please anyone from Dell, please tell me the recommended/support way to solve this problem without creating new/other ones !?
Also, if there is a ProSupport channel other than Netherlands local Dell that IS capable of handling and answering Ubuntu questions for XPS 13 developer edition, please let me know. I don't mind calling telephone numbers in other geographies and/or timezones.
There are several solutions that seem to resolve the issue. The solutions depend on which card you have and which version of Ubuntu you are running. If you are running 12.04 LTS and have the Centrino card, it's a simple kernel upgrade:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install linux-generic-lts-quantal
My workmate and I have been documenting configuration/issues with these Sputnik laptops at the following site. The WIFI issues are here:
