It is a known problem that the NL is at least 20 dBm too high for bcm43xx. > 15[m] form AP - (seems be on edge of range) > Link Quality=35/100 SL=-78 dBm NL=-73 dBm > pcmia atheros shows here SL=-86 NL=-95, works fine though on 5Mbps > > Is it strange to have lower signal level than noise level ? > Does current version uses only 11MBps with 4318 ? I get higher throughput for 11 Mbs even for 4306. Others find that 54 Mbs works for them. It seems to depend on how much noise there is in your neighborhood. For example, there is a broken device near to me that keeps me from using channel 1, even though the nearby AP's are on channels 6 and 11. > What is interpretation of link quality ?

For bcm43xx, I use the firmware-provided value of rssi with quality = 100 * rssi/rssi(max). The maximum rssi was measured here by putting my computer about 5 cm from the AP.
