Noise, more negative is better right?

[armand]

I am experimenting with a bit with the tx power, SNR always seem to show 0, but in general I want as low (more negative) noise number as possible, right?

Noise level and SNR are two different things BTW. SNR = Signal To Noise Ratio.

SNR will show 0 because it doesn't have any signal to compare against the noise level. That value will probably only be of use when connected directly to another router (as a repeater, for example).

The current wireless driver cannot read out the effective (background) noise level from the wireless chipset.
