I've got a problem about the detection of my WiFi card on other Linux kernel versions. When I run ifconfig, the card won't be listed in the network interfaces. The command line sudo ifup ra0 shows the following:
ifup: failed to open statefile /run/network/ifstate: Permission denied
I currently use the "3.8.0-25-generic x86_64" kernel version in order for me to be able to connect to WiFi. All other kernel versions simply won't allow it.
I want to solve this issue before upgrading on 13.10 (I don't think upgrading will solve it at all, or will it?).
Here are all the informations needed:

Thank you very much for your help.
