Description of problem:
While connected to a very weak WAP signal from another building, the
wireless applet nevertheless indicates signal strength near 100%. 
WinXP reports the same signal as "very weak" and wavemon reports s/n
ratios in the single digits.

Disabling the interface leaves the last measured percentage instead of
switching to "N/A".

What is actually being displayed, anyway?  Signal strength as a
percentage of what?

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Install and enable wireless applet
2. Connect to a WAP at long distance and watch the signal strength meter.
3. Toggle the wireless interface between up and down.

Actual Results:  Signal strength meter indicates "very strong" signal

When the link is disabled, a percentage still shows in the signal
strength field and "WiFi" still shows in the status box, but is not

Expected Results:  Signal strength meter should indicate "very weak
signal" (not quite sure what's appropriate).  Disabling the interface
should change the status to indicated that I'm not connected.

Additional info:

On my home netowork, where I'm within about 30 feet of my WAP, signal
strength is in the 70-90% range.

Okay, this is being figured out upstream, but its not trivial. The
link quality reported by the kernel isn't an absolute metric and very
few cards actually report enough information to normalize the value.

Anyway, lets just track the upstream bug:
