Hi there,
I have a Huawei E173u-2 mobile broadband usb stick. It is recognised as a gsm-modem and shows up as such in the networkManager-plasmoid. I have set up the connection details for my ISP (O2), but I can’t connect. When I click on the connection, “signal strength” is shown as well as “operator” (o2 - de). The “connection state” changes to “Preparing to connect”, then “Setting network address”. Then the modem vanishes and comes up again a few seconds later.
Here is the log (/var/log/messages):

It seems like there is a connection for about 5 seconds, then the modem hangs up and restarts :(.
The stick works fine with our windows netbook, so I don’t think it is a hardware failure.
How do I get this working?
