Network Manager won't connect Broadband Modem after disconnect
 
Linux is starting to really annoy me know. I'm really thinking of moving to Windows. Every time the devs update something, SOMETHING BREAKS!

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.

What can I do to fix this? I've given up getting Bluetooth to work, but if this continues, I'm going to crack it.

This is from the system log.

Code:

Using NetworkManager Applet...

I am using the Gnome NetworkManager Applet to handle my network connections. It configures and retains information for network devices and sets up the connection. I can hot-plug back and forth between my cable and wireless internet if I want to play with my router and I've used it to manage a USB modem like yours.

I have an openSUSE 12.2 installation with KDE and used this guide.

You should be able to install the Gnome applet(nm-applet) for the desktop you're using, hopefully solving your problem. Look to the Internet for more information.

It's not the applet, is Network Manager. It makes no different if I use the gnome one, or nm-applet or the KDE one. I suspect an recent upgrade broke it.

I've spent too much time web searching to figure out how to get Bluetooth to work (only to achieve nothing), how to get some software to install on the newer fedora which worked on older ones and the like. I was hoping that someone might know an answer, but I'm not prepared to sacrifice more of my evenings to get Linux working.

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