802.11 Default Channel Selection - Noise V Signal Strength

    Total n00b question here. I've googled but didn't really make much sense of what I found.

    From what I picked up on-line, I should be using channel 1, 6 or 11 (the non-overlapping channels) but I can't figure out which of the three to use for max performance. On 6 and 11 I get high noise measures (30 - 46) with 100 signal strength whilst on Channel 1 I get really low noise levels (around 3) with a signal strength ranging from 60 to the high eighties.

    Which is more important, signal strength or noise reduction?

    The Signal to Noise ratio (SNR) is the best indicator. I'm not really sure about the figures you qouted. SNR is measured in dB, but I don't think you mean 100db when you said you signal strength was 100? Netstumbler will give the SNR.
    Signal quality - Most useful expression of this is SNR or signal to noise ratio. This can be monitored by use of software such as Netstumbler. Generally a SNR of 12 or higher is needed for a full speed reliable connection. Lower SNR value can give slower connection speeds, but give less of a safety margin if the signal is weakened somehow. Signal quality can be affected by other 2.4Ghz devices, eg. video senders etc. Microwave ovens also work in the 2.4Ghz range but won't interfere unless the wireless device is very near.
