I don't know. But the signal level for managed mode is the path from the access point to the receiver, and for mesh mode will vary instant by instant according to which mesh node is transmitting. Perhaps the data is averaged. The snr for each mesh neighbour can also be found with iwpriv. I suspect that the Linux network interface simplication simply does not hold true for this novel design. > * What does the noise power level indicate in physical terms ?

But in my tests noise level represents the expectation of interference from other radio sources, therefore it goes up with solar flux, temperature and proximity to population clusters. There has to be sufficient difference between the noise level and the signal level before the signal can be used. -- James Cameron mailto:[EMAIL PROTECTED] http://quozl.netrek.org/ _______________________________________________ Devel mailing list [email protected] http://lists.laptop.org/listinfo/devel
