Public bug reported:

My Huawei E1762 modem is the only method I use to connect to the
internet. If a dropout occurs (sometime frequently in my location), the
modem is no longer recognised by network-manager and I can't reconnect.

I have tried sudo restart network-manager and sudo restart modemmanager,
this works sometimes after several minutes, but is so inconsistent, it's
quicker to simply reboot to get a connect to the web. I have also tried
physically pulling the usb modem and reinserting with a combination of
the above commands -- nothing seems to work consistently in 11.10.

In 11.04, I could run sudo killall modem-manager from a remote desktop
and get my network going again.

I'm not sure what logs would help debug this. Advice would be
appreciated, please.
