Re: restarting mobile broadband

Hi,

I asked this question on the network manager
mailing list but didn't get answer, so I thought
I'd try here.

I'm a newbie to NetworkManager and have a few
questions.  I have a verizon wireless pcmcia
card.  It is working with NetworkManager, but the
connection drops from time to time and doesn't
restart.  I have the "connect automatically"
configuration option set, and that seems to work
on startup.  But is doesn't reconnect automatically
when the connection dies.  So, here are my
questions:

1) Is there an option that I'm missing to tell it
to reconnect automatically?

On the rare occasions when I have had drops, it seems to reconnect by itself but not instantly. There seems to be a delay before reconnect is attempted.

2) Is there a command-line method to start
the connection so I can roll my own
reconnection script?
3) Is there a way to reconnect a VPN
connection when the mobile broadband
connection is restarted?

Not that I ever found.

4) Is there a way to keep track of total bytes
transferred through a mobile broadband
connection over multiple sessions?  I'd
like to keep track of how close I'm getting
to the Verizon 5GB monthly limit.

Maybe, there is a statistics directory for the device in /sys, with a name like
  /sys/devices/pci0000:00/0000:00:03.0/net/eth0/statistics/
and a file called rx_bytes which may or may not run boot to boot rather than resetting with the connect. Do let me know if that's what you need, and good luck with the VPN. I find that if there are multiple access points NM doesn't even reliably remember which one I was using, so reconnect is reliable as long as the number of available APs is no more than one. That may only happen after suspend, rather than drop...

Keep us posted. ;-)
