    Network Manager won't reconnect Broadband Modem after disconnect

    The problem I am having is this. I have a Huawei E173 broadband modem I use for Internet. It is set up with Network Manager, and was working OK.

    Now, if I disconnect (or get disconnected), I can't reconnect. It fails straight away. The only way is to pull out the USB dongle, wait a moment and reconnect it. Obviously, this is not a desirable fix.

    It seems that the USB device 'disappears' after a disconnect. Perhaps upon disconnect, its deactivated, and has to be plugged back in for the kernel to recognise it again. I suspect an update broke it.

    This is from the system log.

    Code:

    pppd[2359]: unrecognized option 'ppp0'
    <warn> pppd pid 2359 exited with error: pppd options error
    The device should be working, but there seems to be some problem with the ppp options?

    Yet it works when I first turn on my computer. It only fails when I've connected the broadband modem and disconnected. After disconnection, the broadband modem simply fails to do anything, untill I unplug it and plug it back in. so its not ppp options, otherwise it would work at all.

    I've also found that on my desktop PC, which is also using Fedora 18, I've run into the same problem, so it MUST be a bug introduced during an update.

    I just hope it gets fixed with the next round of updates. Problem is, I don't know how to report it, as I can't tell what specifically the problem is.

    It seems to have been fixed with the latest Fedora 18 update.
