One other question...  when this happens, does the indicator show that
you're connected to 3G, or does it show a WiFi connection with minimal
signal strength ( eg. one bar...which looks like a dot )?

When the device is at the extreme extent of an access point's range, it
can get into a situation where data cannot be transfered, yet the phone
still appears to be associated with the access point.  In my testing,
this happens with Android and iOS as well.  It's only after the WiFi
disconnects that mobile data should take over.

Title:
  [krillin] Data connection doesn't switch from Wifi to Cellular

Status in the base for Ubuntu mobile products:
  New
Status in network-manager package in Ubuntu:
  Confirmed
Status in network-manager package in Ubuntu RTM:
  New

Bug description:
  Conditions to reproduce are not clear.
  *Sometimes* when going out of Wifi range, data doesn't switch to 3G. I waited 45min and the connection never established. When I'm back within Wifi range, the device reconnects to the AP and data is working.

  I didn't play with airplane mode.
