[system settings] No indication that Wi-Fi is available ("Prompt when not connected")

[Matthew Paul Thomas]

Ubuntu Trusty r188

0. If you haven't already, connect to a Wi-Fi network.
1. In System Settings > Wi-Fi, turn off Wi-Fi.
2. Turn off "Auto-join previous networks".
3. Switch from System Settings to anything else.
4. Turn on Wi-Fi.

What happens: Nothing.

What should happen: You're prompted to join the previously used Wi-Fi network.

<https://wiki.ubuntu.com/Networking#wifi-connecting-prompted>: "A prompt should appear, suggesting that you connect to Wi-Fi, if all of these conditions are true..."

One other issue that I originally thought was covered by this bug is:

If Wi-Fi is enabled on a Touch device, but the device has never been connected to an AP, unlike Bluetooth there's no indication on the panel that Wi-Fi is on. The only way to tell is by opening the network menu. This could lead to severe battery drain.

It's covered by this bug in the sense that if Wi-Fi is on (as it should be by default), you aren't connected, and you're in an environment where APs are available, eventually you'll get the prompt.

That doesn't cover the case where you're *never* in an environment where APs are available, so you only ever use cellular data. But Wi-Fi isn't the only example of something that might be using power unnecessarily. Those things are listed in the Battery screen of System Settings. <https://wiki.ubuntu.com/Power#Settings>

Re: comment #2 - fair enough.

Should this also cover the case where the user has *never* connected to an AP, and open ( ie. no security required ) APs are available?

[Matthew Paul Thomas (mpt)]

Yes it should, and I think that case matches the specced set of conditions. Please let me know if you find a mistake.

need for this prompt has to be reiterated by the design.
