[Bug 67152] Re: [network-admin] WEP doesn't work when setting key using network-admin

[Stephen G]

Andreas reports that he makes the changes in the "interface properties"
dialog box, then clicks OK but does not see the changes made in the
/etc/network/interfaces config file.

However after that Interface Properties dialog box closes, focus is
returned to network-admin dialog box (titled "Network settings") at that
point, I too see that the config file has not yet been written to.  It
is not until the OK button in network-admin also is pressed that
network-admin writes the changes to the config file.

If instead you click cancel in network-admin, any changes made in
Interface Properties are discarded and never written to the config file.

Additionally, I am experiencing a similar problem in connecting where after making the change (even if network-admin writes the changes to the config file), I still need to manually re-issue the iwconfig to get a connection, or else I can simply reboot:
