To solve this bug I had to insert these lines inside /etc/rc.local ifdown wlan0 ifup wlan0
Seems that the settings in /etc/network/interfaces are written after the wireless network card has already be set up. So the settings are accepted after a restart. -- nm-applet does not save the WLAN password when configured manually https://bugs.launchpad.net/bugs/258404 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
