[maverick] 3G: doesn't connect when SIM is PIN-protected

[alleluia20]

Binary package hint: plasma-widget-networkmanagement

I use a modem huawei e1550 in kubuntu maverick, and (unsuccessfully) try to connect using the Network Manager plasma widget. The SIM card is PIN-protected. Then, the widget connects, prompts "obtaining network address", and then disconnects prompting "not managed". After that, the notifier of peripherals prompts again the disk integrated in the huawei modem, then I try to connect, and back to be beginning, like this forever and ever.

Nevertheless, if I connect in Windows with Mobile Partner (after unlocking the PIN, of course), and reboot into kubuntu, then the plasma widget connects at the first time. The same if I connect in Ubuntu via umtsmon (after unlocking the PIN, of course) and reboot. Here we have an (inconvenient) workaround: connect in Windows or via umtsmon (but umtsmon is not reliable, the connection is often lost), reboot without disconnecting the modem, and connect with Network Manager plasma widget.

The second (and more convenient) workaround is to use nm-applet, after having removed the instance of networkmanager used by kde. nm-applet first asks for the PIN before opening in the panel, and then we can connect without problems. Also, while nm-applet is connecting, the Network Manager plasma widget displays as though it were connecting itself, and finally displays a successful connection (what a cheek it's got :-) ).

Here the shell output:

$ nm-applet
An instance of nm-applet is already running

$ qdbus org.kde.kded /kded unloadModule networkmanagement
true

$ nm-applet

Same on Samsung NC10 with built in 3G-modem. This is a regression from Lucid, where it worked flawlessly. Will probably downgrade, since the function is needed.

I confirm this with a Huawei E620 modem (T-Mobile HU).

Workaround: take the SIM into a handy and remove the PIN.

This was working perfectly in lucid. It even allows you to enter the pin, why doesn't it just use it!? Maverick is becoming pain, first the bluetooth mouse, now this.....
