My new dell xps 13 haswell developer edition ( with ubuntu 12.04) began to have problems with the wifi.
Everything worked just fine till yesyerday when I connected my computer to wifi at work (it worked just fine) and come back home and connected to the usual wifi.
It seemed connected, but the internet didn't work. I have tryied a lot of solutions proposed on this site as, modifying the ilwifi.conf file by adding the command: options iwlwifi 11n_disable=1
.
It works just fine using the cable, and not at all usin wifi. I have installed wicd and the interface tells me that there are no wireless network found.
I have also desactivated the proxy in Mozilla, but still no success. I have also reinstalled the drivers for my wifi card, and again, no success.
Here are the results of some commands when the cable is not connected, that can be helpful:

I also call Dell support for more information and they made me change the channel for the access point to wifi from automatic to 11, because they said it's more compatible with their wifi card. Now it's working. But sometimes it becomes really slow. On the other hand, when I connect it to wifi at work it works great.
