True link quality is a measure of SNR (signal to noise ratio). Signal
strength alone is not meaningful when there is a lot of interference
(noise).

However, Windows NDIS Wireless drivers do not have SNR or Noise available
to do the proper calculation. I think Windows is taking certain tresholds
of Signal power and translating it to arbitrary poor/good/excellent.

Ndiswrapper is reporting Noise power as -256dBm. Instead a more realistic
noise value could be assumed (such as say -90dBm) and SNR and Link Quality
can be calculated based on this assumed value so that these applets could
display something meaningful tracking the signal strength alone.
