Wireless Zero Config. profile not saving

In my Wireless Zero Config. tab, after I add a network (with SSID and WEP
key), it doesn't save under "Preferred networks" even though I can immediatly
connect to that network assuming the setup is done correctly.

It would be fine if I have only one network, but I have to connect to two
network daily (at school and at home) so it does get a bit tedious having to
change and add every time I change network.

Anyone know if I may disabled some wrong services or uninstalled some wrong
stuff??
