I can confirm this bug. It seems it's a duplicate of bug 12074 and of bug 11976 but those bug are quite old : they were reported during January 2005... (and fixed)
I alos noticed network-admin added an "s:" in front of my WEP key wich made it ascii and not hexadecimal but maybe those two bugs are totally unlinked.. ** Summary changed: - [Feisty] network-admin forget static in interfaces + [Feisty] network-admin forgets static in interfaces ** Description changed: Binary package hint: gnome-system-tools When I configure a static connection, network-admin forget "static" in the configuration /etc/network/interfaces : # This file describes the network interfaces available on your system # and how to activate them.
