Thread: mobile broadband connection fails

    Default mobile broadband connection fails

    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?

    My system:
    opensuse 11.4
    kernel 2.6.39-30-desktop (2.6.38 gives the same error)
    kde 4.6.3
    plasmoid-networkmanagement 0.9.svn1192577-168.6

    if you want to fix this problem in kde just uninstall plasmoid and install knetworkmanager.
