I am running Xubuntu (12.04 LTS) and something is wrong with my network settings (for wireless network using DHCP and WPA). Whenever I reboot, after the access to the network is not working unless I restart the network or at least the wlan0 interface:
sudo ifdown wlan0 sudo ifup wlan0
The configuration in
/etc/network/interfaces seems to be correct, because when I restart networking it is working correctly. Any ideas?
In the panel the network manager shows the wireless networks as 'not managed', before and after restarting the network.
