Can anybody say. On my system linux fedora with xfce, password need to
be changed every week, but, when i change my password, NM need old
password for unlocking keyring. How to remove this problem ?

GNOME Keyring and network manager is a problem for me too..
i don't know if keyring is the problem or network manager..

SIM cards get locked by NM passing the wrong PIN to them. [1]

reconstruction:
1 - insert a mobile broadband stick
2 - set up a mobile broadband connection in wizard, e.g. ISP = "o2 mobile"
3 - now create a mobile broadband connection with our beautiful wizard.
4 - enter the PIN where appropiate
5 - tell the keyring to never ask for PIN again, when it offers you that
6 - insert a different mobile broadband SIM from same ISP
7 - select your previously created connection for this ISP

what will happen is:
NM will try to use the old keyring-memorized PIN for the _old_ SIM to unlock the new SIM..
This is how it will automatically enter the wrong PIN more than twice, hereby activating PUK security level blocking of the SIM..

all this happens without any implementation of "keep the user informed" or any options to tell NM that it's about to create a big problem..

the common root of our problems:
NM binds configured connections to passwords/keys.

to fix this:
make NM bind unique devices to real identities, all by unambiguous names.

the same problem matrix appeared recently on what Dan names "Grandmas neighbour's wireless network"..

* identify the password protected object uniquely by an "unambiguous_identifier"
* ask the responsible key holder to supply the key for the "unambiguous_identifier"

in Wireless, Dan fixed this by using the BSSID in a conditional manner.
in Mobile Broadband we might want to identify the SIM card on a hardware level.
it doesn't make sense to believe that same ISP means same PIN code.
