Bug Description
This can be observed both through iwlist and NM.
A wireless network's signal strength is the difference between the signal level and the noise level in dBm.
This is one of the current networks listed through use of 'iwlist ath0 scanning':
Cell 03 - Address: 00:19:2F:A0:53:50
The quality is being reported as 195/70, but in reality should effectively be 0.
In cases where the signal strength is one less than the noise level (ex. signal=-96dBm, noise=-95dBm), the signal is reported as 255/70 and the Network Manager will indicate full signal strength for the access point. Methinks the 255 is a dead giveaway...
