When moving away from wireless signal, the signal strength indicators in WiFi settings do not reflect the signal strength fluctuations.
Repro Steps:

Prerequisites: *WiFi turned ON  *WiFi networks available  *Launch Settings

1) Update a Flame device to BuildID: 20141203040207
2) Open WiFi settings
3) Check available networks list
4) Connect to a network and than move away from the wireless signal source
5) View WiFI indicators in Settings while moving away from wireless signal source

Wifi Icon in both the status bar, and in settings menu do not update dynamically to inform the user of the wifi strength. Basic wifi indicator is broken. Nominating to block 2.2

Hi Vincent, 
Not sure who is the right wifi owner, might need your help to dispatch this.

Hi Arthur, I don't observe getNetworks or getKnownNetworks APIs been called in gecko. Can you help to check it?
Flags: needinfo?(vchang)
Flags: needinfo?(arthur.chen)
We call to getKnownNetworks only when scanning. When signal strength changes, does gaia get notified via the status change event?
Flags: needinfo?(arthur.chen) → needinfo?(vchang)
The signal strength change is reported via connectioninfoupdate event for connected AP which works fine. But I think this bug is related to "Not updated AP lists dynamically" when moving.
Flags: needinfo?(vchang)
From the description, it is about WiFi signal strength indicators. At least we should fix the signal strength indicator of the connected AP. Depending on resources, we can then fix the ones of the other APs.

Arthur, could you take a look at this first approach when you get a chance?

With the current resources, I think we can only update the current connected network, but I'm not an expert of the WifiManager api so, if I'm wrong, please tell me.

After your review, if everything its ok, I will add unit tests to cover this case.

Adding myself and Sam to the loop, as FTU is also affected (kudos Manuel for the heads up).

It would be nice to have the same on FTU, but not a priority for me, as is nog highly probable that the user plays with the app while on the move.

Triage: blocking.
blocking-b2g: 2.2? → 2.2+
Do we need to fix this in branch 2.0 and 2.1?
Keywords: checkin-needed
We need approval for uplifting to 2.1 and 2.0. I think we can leave it until the bug is considered critical and approved.

Resolution: --- → FIXED
Target Milestone: --- → 2.2 S2 (19dec)
Verification is failed due the following issues.

1. WiFi signal indicator in Settings dynamically updates, when moving away from signal,but after tapping "Search Again", the signal icon shows the whole signal bar for a couple seconds.
2. When the device is out of range WiFi signal, the WiFi bar still shows a low signal and never update it
