Hello,
while testing iwlwifi (which works fine now btw) I noticed that the
signal strenght reporting when using mac80211 is broken:
iwconfig only show dBm value....
gnome-netstatus always shows 0%
networkmanager always shows 100%
whats going on? does some has any idea?
is this a known bug or is iwlwifi the culprit?
P.S:
please CC me

A little of both. The wireless statistics code in mac80211 has some strange conventions. I worked
for a while on improving it, but there are multiple opinions regarding the use of terms such as
"level" and "signal". After a few tries, I dropped that part and made bcm43xx-mac80211 conform to
the mac80211 conventions. Now there are lines like "Link Quality=77/100 Signal level=-49 dBm Noise
level=-73 dBm" in the iwconfig output. These values look reasonable.
