[Bug 1436427] Re: Turning off WiFi doesn't set a route after the modem connects data

 

@MIchael

When this happened, did you wait and see whether or not the connection
came back on it's own?

If not, the next time you see it happen, can you check periodically for
a few minutes to see if the connection is restored.  There's a 5m
internal timeout in NetworkManager that may be involved.

If the connection comes back on it's own, then the issue is less serious
than if it's stuck in this state.

Bug description:
  I just switched off WiFi in order to test if the device switches
  successfully to a mobile data connection. After disabling WiFi the
  indicator showed "H" in no time. So it would seem all is fine. I
  opened the browser and no data went through.

  Here's the output of "ip route" and "list-contexts":
