Bug Description

Action Taken:
Power on device and establish wifi network connection. Verify that IP network connectivity exists.
Wait for network (IP) connectivity issue (or induce one).
Ping remote service (host) to ensure there is indeed a loss of network connectivity, yet wifi (802.11) is still connected.

Observed Result:
No indication is provided to device owner that network (IP layer) has become unreachable (except for silent failure of networked apps).

Expected Result:
Network indicator should provide visual cue of a loss of connectivity.
(Attached an example from a competing platform.)

Environment information
Ubuntu 15.04 (r334)
Nexus 7 (2013) flo
rc-proposed channel

I disagree with the notion that Ubuntu (legacy, desktop) should be the model for what makes sense for mobile/device use cases.

In the stationary case (desktop), networks are typically stable. In the mobile case networks are transient and often unreliable. Having no visual cue of network loss diminishes the overall experience.

By the logic in comment #2, Ubuntu for devices should also not support accelerometers. I think that would be a mistake.

I am interpreting #2 as saying that the desktop also has a bug in this case. Laptops also rely on wifi connections frequently.

A lot of applications rely on the network connection, so it would be appropriate to indicate that the network is failing, and not the application.
